The 1" Check Safety Valve is ideal for use in boilers, offering maximum protection to your central heating system. This valve prevents excessive operating pressure by automatically opening when the pressure exceeds a predetermined value, aiming to relieve the system and prevent serious hazards. It is designed to be installed at the highest point of the system, without the need for a switch or tap, ensuring the safe operation of the system.

Additionally, its check design includes two ports—one for fluid inlet and one for outlet—ensuring the flow is always controlled. When the inlet is closed, the flow is interrupted, and when it is open, the outlet flow equals the inlet flow.
