Special Alloy Gate Valve

Lever Operated Ball Valve

A lever operated ball valve uses a manually actuated lever handle to rotate a bored ball a quarter turn (90°) between fully open and fully closed. The quarter-turn action gives fast, positive shutoff, the lever position itself gives instant visual confirmation of whether the valve is open or closed, and the low operating torque makes it the most practical choice for frequent manual operation on small-to-medium bore lines. SEDELON lever ball valves are built to API 6D with a floating ball design and fire-safe, anti-static construction, covering NPS 2″–10″ / Class 150–300 for oil & gas, water, chemical and general industrial service.
