Annual Blowout Preventer

Working principle of the Annular Blowout Preventer The annular blowout preventer is operated by the hydraulic control system. When it’s closed, high pressure oil comes from the middle oil part of the shell into the lower closing cavity of the plunger, pushing the plunger upward, and cone plunger squeezes the rubber core, because of the […]

Cast steel globe valve

Impactor handwheels Globe and stop check valves require higher closing torques than gate valves with the same seat diameter and pressure class. The most economical mechanism for tight shutoff is the impactor handwheel. Two lugs cast under the wheel strike simultaneous blows and give 3–10 times the closing force of standard handwheels. Impactor handwheels are […]
