Oliver Valvetek's Subsea Relief Valves are widely used on hydraulically actuated gate valves to prevent leakage from gland seals entering actuators.
The fail close sprung poppet arrangements have been design and flow tested to prevent pressure build ups by relieving to the sea, and closing to stop the seawater from entering.
The small bore subsea relief valves can be supplied with a range of opening pressures and are suitable for water depths to 3050m (10,000ft). We are also able to work with customers to extend the standard 20 PSI cracking pressure where necessary.
