Shengji adjustable choke valve adjustable choke valve for wellhead  api choke valve

Shengji valve is a reverse acting gate valve with hydraulically actuated compressed piston actuator mounted on it. The valve is designed to be a fail-safe and fail-close gate valve. It is mostly used on high pressure wellhead and X-mas tree, H₂S wellhead and X-mas tree, offshore wellhead and X-mas tree and etc. As a master valve and/or wing valve, it is operated by a remote emergency shutdown device. It will automatically close with the loss of control pressure and will open automatically when the control pressure is restored.

1. Non-elastomer combined seals for stem seals and seals between seat and body.
2. Metal to metal seal between seat and gate & body and bonnet.
3. Back seal design between stem and bonnet allows stem seal change under pressure
4. Hard alloy spray on the surface of valve gate and seat.
5. Excellent performance of anti-corrosion and anti-abrasion
6. Heat treatment and elaborate machining for pressure containing/pressure control parts. Small rotating torque.
7. Shengji PR2 valve test is certified by DNV. Its performance meets the full requirement of the PR2 standard.
