Overview

The through-conduit, cast-body GROVE G12 gate valve is fully compliant with API Specification 6D. This series is particularly well suited for projects requiring special materials and trims. The top-entry construction enables easy maintenance in a wide range of applications, such as in oil and gas pipeline main valves, manifolds, station valves, pig launcher traps, and ESD. The traditional field of application is in oil and gas transmission and distribution, both onshore and offshore.
