Air Compressor Pressure Relief Valve | 304 Stainless | 1/4" or 1/2" BSPT

This air compressor pressure relief valve is a small spring-loaded safety valve in SUS304 stainless steel, sold with a fixed set pressure from 0.5 Bar to 10 Bar and a 1/4" (DN8) or 1/2" (DN15) BSPT male thread. It is fitted to a compressor, air receiver or pipeline and opens to vent gas when pressure rises to the set value, so the system is not pushed past its limit. Features and benefits: - Fixed set pressure in 11 steps: 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 Bar, so you pick the value that suits the system rather than adjusting a spring - Two thread sizes: 1/4" BSPT male (DN8) and 1/2" BSPT male (DN15), to suit common tank and manifold ports - SUS304 stainless steel material: resists rust on workshop air lines where moisture collects - Spring-loaded safety structure: relieves excess gas pressure through the exhaust without any power supply - Compact mini body: fits on small receivers and tight pipework Applications: - Air compressor receivers and tanks - Compressed air pipelines in workshops - Gas pressure systems that need a fixed over-pressure vent - Spares and replacements for compressor maintenance Note: Choose a set pressure at or below the lowest rated pressure of the vessel or line it protects. Fit it where the outlet is clear, point the exhaust away from people, and do not block or modify it. The supplier's listed working pressure is 0.1 to 0.8 MPa (fixed).
