Applications:
A safety valve is an indispensable valve to protect your equipment. It is installed in the pressure vessels and can be triggered to actuate when the pressure of the inlet side reaches a pre-set level, releasing the fluid and avoiding damages to your facility. More importantly, it serves as a fail-safe system in case of any system failure on the surface.
Subsurface safety valve (SSSV) is a device that provides emergency closure capability. It is connected to the wellbore by the stainless steel control line which is attached to the outside of the tubing string. Depending on the wellhead pressure, the control line may need to keep as high as 10,000 psi to keep the valve open.
Apart from SSSV, more such valves make sure that your facilities are executing optimal safety and can be used in the applications like chemical injection, subsea safety valves, velocity strings, work strings, steel tube umbilicals and geothermal coiled alloy tubing.
