To ensure the safe operation of every closed heating system, it is necessary to install a safety valve. Safety valves are designed to protect systems against exceeding the allowable pressure value. The opening pressure is set at the factory and can not be changed. Safety valves can be used in pressurized water and central heating installations. This particular model releases some of the liquid after a pre-set pressure is reached.
