Safety valve, type-approved, preset and sealed, G 1/2", DN 10, 21.50 bar, brass

This free-blowing safety valve protects compressed air systems against exceeding 21.50 bar. At full lift it discharges 914.7 m³/h and thus limits the pressure rise in vessel and pipework. It is fitted with a G 1/2" thread, works in nominal size DN 10 and is made of brass.

Benefits

• Fixed setting at 21.50 bar and lead-sealed, so the set pressure is protected against unauthorised adjustment.
