BALL VALVES
Standards and Specifications
Ball valves are mainly designed to conform API 6D (Specification for pipeline valves) and ANSI B16.34 (Valves Flanged, Threaded and Welding End) or API 6A (Specification for Wellhead and Christmas Tree Equipment) in case of upstream applications. Other related standards such as ANSI B16.5 (Pipe Flanges and Flanged Fittings), ANSI B16.25 (Buttwelding Ends), ANSI B16.10 (Face to Face and End-to-End Dimensions of Valves) are also used for the design of ball valves. Also our ball valves are designed to meet FIRE SAFE requirements to BS6755, API 6FA and API 607. Final testing is done to conform API 598 (Valve Inspection and Testing) MSS-SP-61 (Pressure Testing of Steel Valves) API 6D (Specification for Pipeline Valves) or API 6A (Specification for Wellhead and Christmas Tree Equipment) requirements. Materials are selected mainly to ASTM standards and when sour service is specified to meet NACE MR-01-75 (Sulfide Stress Cracking resistant Metallic Materials for Oilfield Equipment).Gas-Over-Oil Actuated Valves
This valve is used in gas pipelines and the actuator is powered directly from the line gas pressure. Valves actuator may be provided with line break detection system which closes the valve in case that the gradient of pressure drop in the line is greater than a preset value.Emergency Assisted Ball Valves
This valve is intended for protection of turbine/pump in hydroelectric power stations. Valve is assembled in horizontal position and provided with a hydraulic piston to open the valve. In case of reverse flow which may damage the turbine/pump, this is detected by a pressure transducer which sends a signal to the valve releasing the pressure in the hydraulic piston and allowing the valve counterweight to close the valve in few seconds avoiding line counterflow to reach the turbine/pump.Fully Welded Ball Valves
ully Welded ball valves are available for those cases when leakage throughout atmosphere must be absolutely avoided such as in gas transmission pipelines. Valve is built in three pieces fully welded constructions.Top-entry Ball Valves
The Top-entry valve types have a major application when a frequent maintenance must be carried out and the valve can not be easily removed from the pipe. In this valve model, all the internals can be easily dismounted by loosening the bonnet of the valve and removing the ball, the seat-holders and the shaft. When mounting the valve again, the seat-holders have a system to regulate the compression of these to the ball.In-Line Serviceable Ball valves
For sizes up to 6”, this type of valve can be used giving the same possibility of maintenance as top entry ball valve but being a construction much more economical.API6A Ball valves
For upstream applications, three pieces side entry ball valve is used in accordance with the requirements of API 6A. Valve classes from class 2000 to class 20000 In sizes from 2-1/16” to 7-1/16” are available. Material selection is done in full compliance with API 6A requirements. Valve designs are available to meet Pressure Product Requirement levels PSL-1, PSL-2, PSL-3 / PSL-3G and PSL-4.



Non contact top entry ball valve
Non contact top entry ball valve
Description
Ringo Válvulas NCBV non contact top entry ball valves series are designed and produced according to API 6D/ ISO 14313, API 6A, API 6DSS / ISO 14723, BS5351, ASME B16.34 and other international standards as well as customer specifications on request.
These valves are built of a single piece body with a bolted bonnet. This design is a robust construction that provides a good performance, smooth operation, minimum pressure loss, high Cv values and also allows bonnet disassembly on site to perform inspection, maintenance or repair without removing the valve body from the pipeline.

The Top-entry valve types have a major application when a frequent maintenance must be carried out and the valve cannot be easily removed from the pipe. In this valve series, all the internals can be easily dismounted by loosening the bonnet of the valve and removing the ball, the seat-holder and the shaft.
Valves can be supplied manual operated or with any kind of operator for ESDV, SDV, BDV, MOV, GOV or LBV functions (electric drive, pneumatic, hydraulic, electro hydraulic or pneumo-hydraulic actuator).
Valve Size-pressure rating

Design characteristics range

Working Principle
NCBV Ball Valves have a ball which is supported by a bottom trunnion. When the bore is oriented to the pipeline direction, valve is in the open position, allowing the fluid pass through. The stem start moving down and due to the channels machined on it in spiral it turns 90o forcing the ball to turn the same. Then the channels are machined straight and the stem cannot turn moving only down.
In this situation due to an angled surface, the stem pushes the ball that pivots on the bottom trunnion and contacts the seat. Ball only contacts the seat in this position then there is not friction during the rest of the stroke.
Ringo Válvulas can supply NCBV ball valves in two configurations:
- Full Bore: Size of the trim is the same of the pipeline. In this case valve is suitable for pigging. Special large bores for particular PIG dimensions are available on request.
- Reduced bore: Size of the trim is smaller than the pipeline size. Number of reduced sizes is according to API 6D unless otherwise is agreed for the particular job.

A) Soft seats
The seat assembly consists in an outer metallic seat carrier with a soft seat insert. The soft insert is located into a groove in the metallic seat carrier.

B) Metal seats:
When there is presence of solid particles in the fluid that could damage the soft seat insert or for either high temperature services or high pressures, where soft insert cannot withstand it. Seats consist of a metallic ring where surface in contact with the ball is hardfaced with Tungsten Carbide, Chromium Carbide, Stellite etc., achieving a hardness up to 74 HRC (Tungsten Carbide). This makes the design long durable and reliable and able to achieve classes C & D leakage class metal seated.

Axial Nozzle Check Valve
Axial Nozzle Check Valve
Description
Check valves are used in numerous installations for various purposes and it is always a challenge for the planning engineer to find suitable return flow preventers. Often it does not become evident until a plant is being run on test that the selected non return valves slam heavily and produce high pressure peaks which exceed the permissible pressure to such an extent that the installation and the surroundings are endangered. A further important factor in the present and future is economy (the savings of energy). A feature of the Samson Ringo Axial Flow Check Valves is its inherent non slam characteristic. This is achieved because the valve reacts so quickly to flow changes. This causes that the valve change the point of closure without letting any possible reverse flow. This avoid water hammer effect for liquid service and ensures no chance of reverse flow into the compressor for gas service. Additional benefits of the Samson Ringo Axial Flow Check Valves design are:- Low pressure drop and turbulence due to the streamlined flow path.
- Extremely long service life because the moving parts are not subjected to the shocks associated with typical asymmetric valve designs.
- The valve has no soft parts to wear, cause misalignment, or need replacing.

Body design
A streamlined body with constant sectional area, offers a very reduced coefficient resistance and gives larger Cv values for the same sizes. Fluid is channeled into an annular path between the inner and outer bodies until it reaches the characterized cage. Smooth changes in flow direction and no turbulences contribute to lower noise levels. The high capacity, combined with the large rangeability, make our axial valve to be acknowledged as the ideal design to control over the full range of process conditions with a single valve. As an option extended body neck is offered for cryogenic operations. Low emission is guaranteed by the O-ring seals combined with back-up packing. Distance between flanges is in accordance with ISA 75.03 when data are available or API 6D for larger sizes. Actuator flanges are machined according to ISO 5211 or other standards. All types of quarter turn actuator are easily mounted. Casted range from 4” to 48” and ratings from 150# to 2500#. Forged three pieces for sizes below 4” and pressures above 2500#. Constant flow passage area ensures the maximum possible capacity for on-off application due to reduction of the K resistance coefficient.Trim design
Advantages of stem guided plug:- Can be used for on-off application without cage in order to achieve high capacity.
- Control is performed by hole pattern.
- Possibility of using multi-cage designs to perform multistage pressure reduction of high noise/cavitation conditions.
- Availability of balanced plugs, to reduce the required actuator torque.
- The inner chamber, wich includes the transmission system is pressure balanced, due to that no fluid movement is occurring inside this area.
- Bearings of transmission mechanism are protected against particles by a cover.
Drive Mechanism Design
- Multiplier effect reduces force torque and actuator size.
- It is not affected by dirt, impurities or fluid conditions.
- No gap, low friction bushings in crank and rod junctions assure a smooth, no backlash movement of the plug.
- The drive mechanism is designed to multiply the actuator force applied to the plug when it is needed. This feature makes it possible to select lower torque, smaller size actuator and reduce operating times.
- КрAdditionally it improves the valve inherent rangeability. At the beginning of the opening a large angle of rotation means a small change in the stroke of the plug. Good for start-up conditions with small cv values.
- All together it combines to give smooth, accurate fast operation of the valve with smaller size actuator and enhanced ran- geability.
- Low friction sealing of rotating shaft.
- Low friction bearings in the transmission of movement, from shaft to plug stem.
- Plug, guided by the stem is fully balanced in both axial and radial directions and gives no friction to cage.
- Multiplier effect that reduces the required actuation force.
- Maximum force is delivered when it is most needed at opening and closing.
- All the above combine to greatly reduce the torque, the size of the actuator and the operating time.

HIPPS
HIPPS
SAMSON RINGO HIPPS IS PROVIDED
Initiators (pressure transmitters)
HIPPS are typically supplied with three pressure transmitters that monitor the pressure in the line and provide the information to the next element. This three elements can be selected from the same supplier or three different ones; supplying the pressure transmitters of three different brand avoid what it is call a “common fail”, for instance a quality problem in a lot of Pressure Transmitters produced by the same manufacturer that could affect to the proper performance of the HIPPS. HIPPS is designed to be able work only with two Pressure Transmitters for a while. This is to allow to make some checking or to replace any of them with the HIPPS under operation. In such case, system is working in “degraded mode” and logic solver receives that information.
Logic Solvers
Logic solver is the device in charge of processing the input signals received from the initiators and it is configured to send the signal to operate the final elements, when the received input is above the preconfigured pressure value. Ringo can supply HIPPS with different types of logic solvers:
Final Elements
Final elements have the function of isolating the downstream part of the installation from the overpressure. Typically, final elements consist of two valves with their related actuators installed in serial to be closed when the signal is received from the logic solver. Actuators may be pneumatic or hydraulic and are supplied with their own control panel, including the solenoid valves to govern their operation. Actuators are sized to provide a very fast operation time (less than 2 seconds). Samson Ringo offers two type of valves for HIPPS: Ball and Axial.

Axial Valves
Design:
A stream lined body with constant sectional area, offers a very reduced coefficient resistance and gives larger Cv values for the same sizes.
Fluid is channeled into an annular path between the inner and outer bodies until it reaches the characterized cage. Smooth changes in flow direction and no turbulences contribute to lower noise levels. The high capacity, combined with the large range ability, make our axial valve to be acknowledged as the ideal design to control over the full range of process conditions with a single valve.
As an option extended body neck is offered for cryogenic operations, with a variety
of sealing wafer. Zero emission is guaranteed by the O-ring seals combined with back- up packing. Distance between flanges is in accordance with ISA 75.03 when data are available or API 6D for larger sizes. All types of quarter turn actuator are easily mounted. Our model RAX Cv features:
