Prescor B valve 1/2 x 1/2-6bar

For protecting water heaters and potable water systems.
When the system pressure reaches the set pressure, the Prescor B boiler valve begins to vent, whereby the pressure stops rising. If, due to specific circumstances, the pressure rapidly rises over the set pressure, the Prescor B boiler valve will open fully, creating a large blow off capacity. This is a permanent, reliable safeguard against overpressure. Venting can be prevented by installing a suitably sized Airfix expansion vessel for sanitary systems.

The seating of Prescor boiler valves is designed so that it not only makes a perfect seal but can also achieve a large blow-off capacity.
The hardness of the rubber is adapted according to the set pressure of the safety valve. Due to this combination of a specifically designed seating and special rubber it is possible to achieve optimum safety.

• Wide range so that the correct valve can be selected appropriate to the application.
• Can be used in combination with any storage boiler system.
• Because of the pop effect these valves have a high blow-off capacity.
• Solid brass housing.
• Valve seat with silicon free rubber seal.
• Anti-ageing steel spring maintains the set pressure accurately.
• With silicon free diaphragm that prevents moisture and dirt from getting into the moving parts.
• Construction and choice of materials are your guarantee of accuracy and safety.
