API 6D Rising-Stem Ball Valve, Class 600

A rising stem ball valve combines quarter-turn ball isolation with an axial stem lift that moves the ball away from the seats before rotation. This positive mechanical action reduces seat friction, breakaway torque and wear during frequent operation, making it a strong option for critical gas, liquid hydrocarbon and compressor-station isolation. Forged body materials, fire-safe construction, anti-static protection, double block and bleed, emergency sealant injection and RF, RTJ or butt-weld ends are available. Gearbox, pneumatic, hydraulic and electric actuation packages can be configured to the project torque and fail-action requirements.
