SAFETY VALVE FLAMCO 3/4x6 bar FT BRASS

Product code
3941010
Prescor safety valve for domestic water to protect hot water tanks. When the system pressure reaches the set pressure, the Prescor B safety valve begins to drip, stopping the pressure rise. If, due to conditions, the pressure suddenly rises above the set pressure, the Prescor B safety valve opens fully, achieving a high discharge capacity. This is a permanent and reliable safety feature against overpressure. Dripping can be prevented by installing a properly sized Airfix domestic water diaphragm tank in the domestic water system. The Prescor safety valve seat is designed to form a perfect seal while enabling high discharge capacity. The hardness of the rubber is also appropriately matched to the safety valve’s set pressure. Thanks to the combination of a specially designed seat and rubber, optimal safety can be achieved. Prescor safety valves can be used with any water heater. Features
