Prescor safety valves have a special shape which, not only achieves a perfect seal but also provides a large blow off capacity. 

The valve seal is made of high-quality rubber which is heat resistant to 140 °C and where the hardness of the rubber adjusts to the set pressure of the safety valve. In this way, the valve cannot stick to the seat.

All valves are tested before they leave our facility and are available for heating and cooling installations as well as for protection of various hot water storage appliances.
