Stainless steel spring safety valve is applicable corrosive medium. When the pressure in pipes is higher than set pressure, safe valve will open to decompress to ensure the safety of pipes. When the pressure in pipes is lower than set pressure, safety valve will close.
Nominal diameter: DN25-150mm
Nominal pressure: PN64MPa
Working temperature: ≤300℃
