Water Safety Valve

Water Safety 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.

Series - 150 To 600

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.
