Bulgin GRV50 Gas Check Valve Brass 1 1/2" (40mm) BSP Female

The Bulgin GRV50 Gas Check Valve is an industrial non-return valve designed for the protection of ring lines, tapping points, and points of use in gas distribution systems. Manufactured from durable brass and aluminium alloy, this safety device provides reliable pressure-related safety functionality with a low position-independent cracking pressure, ensuring sensitive system protection. Suitable for a wide range of fuel, oxidising, and inert gases, it is ideal for industrial applications where flame arresting is not required.
