Safety Valve
DN 20 x 32 ~ DN 150 X 250
Pressure: PN16~ PN 40
Material : Cast steel , A216 WCB , SS304

Spring type safety relief valve works through adjusting spring force to prevent medium pressure and realize sealing purpose. Under the condition of spring force greater than medium's normal pressure, valve disc is at the close state, when medium pressure exceeds the set pressure, the spring is compressed, and lead the disc sealing faces separated, the valve open automatically, and relief pressure; When medium pressure reduced to normal pressure, the valve disc go back to valve seat under the spring force, disc sealing faces and valve seat sealed again, the valves close automatically.
