Springs for ARI Safety valves

Safety valves are delivered according to each clients specific set-pressures, and the springs have different pressure ranges according to valve dimension etc. BAGGES are certified by ARI Armaturen to change the set-pressure and change the springs in ARI's standard safety valves within a specific range of sizes and set-pressures. We have our own ARI test bench.

Please contact BAGGES for further information regarding re-setting or changing the springs in existing safety valves.

Standard spring material is FDSiCr / 51CrV4 (1.8159) for valves with bodies in cast iron, nodular iron and carbon steel.

For stainless steel valves it is standard with spring in stainless steel 1.4310 (or FDSiCr / 51CrV4, 1.8159 with special coating).

For ARI-SAFE-SN (Semi Nozzle) and ARI-REYCO R & RL (Full Nozzle) valves, other spring materials are used.
