Description

Product Description

Fisher YD and YS three-way cage-guided valves are designed for both throttling and on/off control applications, featuring balanced or unbalanced construction options to suit different operating conditions. The YD model handles both converging (combining two flows into one) and diverging (splitting one flow into two) services, while the YS is optimized specifically for converging applications. These robust valves are particularly well-suited for demanding oil and gas production environments, offering reliable performance even in challenging conditions involving sulfide and chloride stress-corrosion. Their cage-guided design ensures precise plug alignment and stable control, with balanced versions available to reduce actuator load in high-pressure differential situations.

Features

  • Cost-Effective Actuator Compatibility
    The YD valve’s balanced plug design allows pairing with smaller, more economical actuators, significantly reducing procurement and installation costs.

  • Modular Design Reduces Maintenance Costs
    A single valve body accommodates multiple trim configurations while utilizing Fisher easy-e universal bonnets, gaskets, and packing systems – minimizing spare parts inventory and expenses.

  • Purpose-Built for Three-Way Control
    Engineered specifically for diverting/mixing applications, available in multiple sizes (NPS ½”-6″), end connections (flanged/butt weld, etc.), port diameters, and trim materials to meet diverse process requirements.

  • Eco-Sealing Option
    Features the optional ENVIRO-SEAL  packing system delivering superior sealing performance with optimized load transmission for extended service life.

  • Wear-Resistant Hardened Components
    Hard-faced trim materials (e.g., Stellite) ensure long-term reliability in high-erosion applications.

  • Maintenance-Friendly Architecture
    Cage-guided design enables quick disassembly for inspection, with replaceable plug-and-cage assemblies. Packing components are interchangeable with Fisher easy-e valve series for simplified maintenance.

  • Stable, Quiet Operation
    Robust cage guidance system dramatically improves plug stability, effectively suppressing vibration and mechanical noise in sensitive processes.
