- The WS-BSO gate valve was designed for use as a manual valve in high pressure, large bore applications.
- A ball screw mechanism and lower stem are incorporated into the WS-BSO gate valve to minimize the actuating torque.
- Bi-directional design provides flow direction flexibility and increased service life.
- Sealing at the gate-to-seat and seat-to-body is metal-to-metal.
- Two spring-loaded, pressure energized, non-elastomeric lip-seals provide maximum protection against intrusion of particle contaminants into the body cavity and seal areas, improving gate and seat service life, prevent damage to the body-to-seat seal face and improve valve performance at very low pressure.
- Lower stem balances pressure thrust on upper stem to reduce operating torque, prevents body cavity pressure build-up during operation and provides position indication.
- Spring-loaded, pressure energized, non-elastomeric stem seal covers full range of pressures, temperatures, and fluids.
- Pressure-energized metal-to-metal bonnet seal.
- Either stem can be back seated to allow stem seal replacement with valve under pressure.
- Grease injection fittings located on the downstream side of the stem and the balancing stem backseat for safety.
- The WS-BSO gate valves meets or exceeds API 6A standards.
- Forged body & Bonnet
- Low operation torque
- Metal-to-Metal body/bonnet seal
- Metal-to-Metal sealing gate-to-seat and seat-to-body
- Lubrication fittings for easy maintenance
- Bi-Directional Slab Gate- Ball screw stem for manual operation
- The stem packing is a pressure energized seal that can resist severe temperatures and fluids- Flanged & Studded outlets are available
