- 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
- 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.
- The ENVIRO-SEAL™ packing system option is available. This packing system provides excellent sealing, guiding, and loading force transmission.
- Hardened trim materials provide excellent wear resistance.
- Cage-type construction simplifies inspection and removal of parts.
- Packing parts, including packing flange, studs and nuts, and packing kits are common to the YD, YS, and Fisher easy-e control valves.
- Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise.
