Manually Actuated Multi-Turn Subsea Gate Valves
Oliver Valvetek offers a comprehensive range of engineered-to-precision Subsea Manually Actuated Gate Valves. Available in two different bore sizes – 3/4″ and 1 inch, they are suitable for up to 10,000 ft of water depths and a cold working pressure rating up to 15,000 PSI.
Our Manually Actuated Subsea Gate Valves provide the end-user with low flow restrictions and metal-to-metal seat sealing isolation. We also utilise Tungsten Carbide (HVOF) hard facing technology which ensures that the sealing is gas-tight (meeting with API6A PSL3G). This is extremely useful for applications such as chemical injection on subsea Christmas trees and Manifold Structures. We also perform qualification testing to the exacting standards of API 6A Appendix F PR2 and 17D 2nd Ed and supported by Third Party Independent review and endorsement.
Suitable for Remote Operating Vehicle (ROV) usage, our Manually Actuated Subsea Gate Valves have been used extensively by our customers worldwide for projects both small and large in size. Commonly found on Oil, Gas and Petrochemical projects, we offer both Half-Turn and Multi-Turn gate valves, offering a truly uninterrupted process flow through the valve and low operating torques.
We thoroughly test and qualify each Manually Actuated Multi Turn Gate Valves to different pressure ratings and water depths. With a maximum pressure rating of 15,000 PSI (1,034 bar) and a maximum water depth of up to 10,000ft (3,050m), our Manually Actuated Subsea Gate Valves are rated as a high performer within subsea applications and throughout the industry
