Description
Features and Specifications
- ENVIRO-SEAL™ packing systems provide an improved stem seal to help prevent the loss of process fluid.
- The stainless steel materials, specialized seals, and extension bonnet are designed to meet cryogenic temperature requirements.
- The metal-to-metal seat is designed and manufactured to provide long-lasting, reliable, tight shutoff at both ambient and cryogenic temperatures, without the need for periodic lapping.
- Rugged cage guiding for the ET-C and EWT-C provides high valve plug stability, which reduces vibration and mechanical noise.
- ET-C and EWT-C balanced valve plugs permit the use of smaller, lower-cost Fisher actuators.
- Low flow requirements can be satisfied with standard restricted-capacity trim or with Micro-Form, Micro-Flute, or Micro-Flow valve plugs.
- Extensive cryogenic testing during the development of the valve design reduces the need for expensive cold testing for most applications, which results in quicker delivery and greater value.
