Rotary Gate Valves

The subsea rotary gate valve was introduced into the market by Bentley in 1998. Since then it has gained universal acceptance throughout the industry. It has become the product of choice globally, with many customers preferring and trusting this design over traditional needle, ball and slab type gate valve designs.

With an unparalleled experience in the design and manufacture of the rotary gate valve, the beautiful simplicity of its operation has proven it to be hugely reliable in service, enabling Bentley to provide a SIL 2 rated product with the widest range of features and accessories available today.

A wide range of sizes, pressures, materials and interfaces are available from 3/8″ through to 1″ nominal bore, up to 15,000psi (1,034 bar) in both FF and HH trims. Designs are qualified to API 6A 20th Edition and API 17D 2nd Edition for the temperature range -29°C to 150°C, to a water depth of 10,000ft.

The simplicity and versatility of the rotary gate valve is immediately apparent when the orientations and variations are considered. Almost any style and combination of inlet / outlet connections can be provided and there is also an extensive range of proven manual interfaces.
