Product Description

The YJ-RB bleed valve provides controlled venting of process media to atmosphere for instrument isolation and pressure release. The valve features a compact threaded body suitable for installation on gauge valves, manifolds, and transmitters.

A hardened stem with surface treatment improves wear resistance and extends service life. The precision sealing interface ensures tight shut-off even after repeated venting cycles. Multiple material options (316 SS, Alloy 400, C-276) allow compatibility with corrosive or high-temperature media.

Each valve is factory pressure-tested at rated working pressure before delivery to guarantee leak-free performance.
