Pressure Relief Valve
for pipeline installation
For 6918-10-001 housing made of zinc, for 6918-10 housing made of ductile iron.
Control piston made of steel, hardened. Can be sealed on setting spindle.
The pressure relief valve is used to protect against exceeding the maximum permissible pressure for the system (safety valve) or to limit operating pressures. Once the set pressure is reached, the valve opens, the excess liquid in the system flows back into the tank via the T line of the pressure relief valve. The pressure relief valve is not suitable for the protection of pressure equipment as defined by the PED 97/23 / EC.
