GROVE G12

Gate valve

The Cameron GROVE G12 gate valve is a through-conduit gate valve with a cast body. The valve is fully compliant with API Spec 6D. This series is designed for standard application, but the design also is particularly suitable for projects where special materials and trims are required. The top-entry construction allows easy maintenance in a wide range of applications such as in oil and gas pipeline main valves, manifolds, station valves, pig launcher traps, and emergency shutdown (ESD). The traditional field of application is in oil and gas transmission and distribution both onshore and offshore. The valve is also used for renewable fuels service.
