BALL SCREW GATE VALVE

Our ball screw gate valve is designed for large bore, high pressure, manual valves to ease user operation. The bottom balanced stem and ball screw principle gives our valves convenient and easy operation with low torque. 

Features and Benefits

 

 

• Bi-directional design provides flow direction versatility and increased service life.
• Positive metal-to-metal sealing (gate-to-seat and seat-to-body).
• Simple, reliable gate and seat design promotes ease of field service and minimal spare parts inventory.
• Two spring-loaded, pressure energized, non-elastomeric lip-seals between each seat and body assist in low pressure sealing. They also protect against intrusion of particle contaminants into the body cavity and seal areas.
• 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 backseated 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.
