wellhead surface safety valve
With 30 years of experience, Sanjack is devoted to designing, researching and developing pumping units.
It has an annual sales volume of up to 1200 units.
Sanjack pumping unit cover the API conventional and unconventional pumping units.
Relying on technical strength, complete equipment, scientific production fixture and strict production process;
The Sanjack wellhead surface safety valve is a reverse acting gate valve with hydraulically actuated compressed piston actuator mounted on it. The surface safety valve (SSV) is designed to be a fail-safe and fail-close gate valve. SSV 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.
- Prompt open/close control
- Remotely operated with a high safety performance
- PR2 gate valve with a long service life
- Used as a master valve or a wing valve.
- Recommended for use in high pressure and/or large bore applications
