Adjustable choke valve is classified from adjusting mode as needle choke valve, barrel choke valve, wedge choke valve and orifice choke valve. Valve needle and trim is made of hard alloy with the feature of abrasion, washing and corrosion resistance. It is vital in adjusting flow, pressure and closing. Needle structure is mainly applied in […]

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 […]

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 […]

The working medium flows in single direction.

The choke manifold is support equipment of hydraulic BOP for controlling well blow out and well pressure. Through the choke valve, perform well killing, replacing polluted slurry in well. Control wellhead pressure of casing and standpipe, restoring mud to control pressure at well bottom to stop overflow. Through relief pressure, decrease wellhead pressure to perform […]

The yoke is designed according to ISO5211, which is convenient for installing gearbox, pneumatic or electric actuator. In addition to the wear-resistant standard V-ring packing, graphite high-temperature packing and low-leakage packing can also be adopted. The bi-directional sealing can be the option

Full bore design eliminates efficiently pressure drop and vortex, and eliminates washing by solids in fluid. Gate use expanding type structure. Achieve low torque operation and low wastage during open and close. Metal seal is used between bonnet and body. Soft seal or metal seal is used between gate and seat. Inject sealant through injection […]

FC Type Slab Gate valves are widely used at Wellhead equipment, Christmas tree, manifold plant equipment and pipelines. Full bore design, effectively eliminating the pressure drop and eddy Valve body and bonnet, gate and seat, seat and valve body are both metal to metal sealing. Bonnet and stem designed with back seal, easy to replace […]

Fracturing wellhead is the product which connects the high pressure outlet of multiple sets of fracturing car with high pressure elbow and high pressure tee and then connects them to wellhead with one or more outlets；The theory that pressure of multiple fracturing pump can be accumulated is applied. As multiple fracturing cars are working at […]
