Ball Screw Gate Valve

Product Overview: The Ball Screw Gate Valve incorporates an advanced ball screw drive mechanism that reduces manual operating torque to just one-third (1/3) of standard gate valves. Engineered with a flat gate configuration and a pressure-balancing tail rod, this valve is optimized for large-diameter, high-pressure oilfield applications—providing smooth operation, visual position indication, and long-term reliability in severe environments.

Key Features & Advantages:

• 70% Torque Reduction: Precision ball screw drive mechanism reduces operating torque to 1/3 of conventional valves for effortless opening and closing.

• Pressure-Balanced Tail Rod: Integrated tail-rod structure neutralizes internal pressure forces, ensuring equalized stem load and precise position indication.

• Large-Bore, High-Pressure Rating: Designed for heavy-duty service with pressure ratings from 2,000 PSI up to 20,000 PSI.

• Sour Service Compatibility: Built to handle harsh media including crude oil, natural gas, drilling mud, and corrosive H₂S/CO₂-bearing fluids.

• Wide Thermal Range: Performs reliably across severe operating temperatures from -46°C to +121°C (LU Temperature Rating).
