FISHER YD and YS three-way cage-guided valves are designed for throttling or on/off service, and are available in balanced and unbalanced constructions. The YD valve is used in general converging and diverging service. The YS valve is used in general converging service
Economy: Balanced valve plug construction in the YD permits use of smaller, lower-cost actuators. A single one-piece valve accommodates both trim designs and uses FISHER easy-e™ bonnets, gaskets, and packing, thus cutting spare part inventory costs.
Application Flexibility: Multipurpose capability results from a valve designed specifically for three-way control. A variety of valve sizes, end connections, port diameters, and trim materials provides design versatility for your control needs.
Excellent Sealing Capabilities: The ENVIRO-SEAL™ packing system option is available. This packing system provides excellent sealing, guiding, and loading force transmission. The improved sealing of the ENVIRO-SEAL system can help control emissions to below the EPA (Environmental Protection Agency) limit of 100 ppm (parts per million) from valves. The ENVIRO-SEAL packing systems feature PTFE, Graphite ULF, or Duplex packing with live-loading for reduced packing maintenance.
Long Trim Life: Hardened trim materials provide excellent wear resistance.
Easy Maintenance: Cage-type construction simplifies inspection and removal of parts.
Valve Plug Stability: Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise.
