Gas Non-Return Valve GRV32 Brass G1 Female

Gas Safety Device (Without Flame Arrestor)

Industrial gas safety device designed for the protection of ring lines, tapping points, and points of use. This unit provides reliable pressure-related safety functionality but is not flashback resistant and not flashback proof, making it suitable for applications where flame arresting is not required.

Engineered for stable operation with position-independent low cracking pressure, it supports a wide range of fuel, oxidising, and inert gases in industrial gas distribution systems.
