GOST Gate Valve

A GOST-standard gate valve built to Russian / CIS specifications for on/off isolation in oil, gas and process pipelines.

Overview

The Gost Gate Valve is manufactured to GOST (Russian / CIS) dimensional and material standards so it drops directly into pipework engineered to those codes. It is a cast-body on/off isolation valve that seals a full-bore opening with a flexible wedge and rising stem, providing drop-tight bidirectional shut-off without being used for throttling. Compliance with GOST 3325, GOST 9544 and related standards ensures correct face-to-face dimensions, testing and traceability for projects in GOST-governed markets.
