Fire Valves
The fire valves on this page are DIN flanged swing check valves used to prevent backflow in fire systems. The disc opens in the flow direction and closes onto its seat under its own weight and reverse pressure when the flow stops.
The store range includes models marked 300 psi and PN16 in 2″, 2½”, 3″, 4″, 5″, 6″, 8″, 10″ and 12″. They are preferred at fire pump outlets, tank connections and hydrant mains as large, low-loss backflow preventers.
Main Applications
- Fire pump discharge lines
- Fire water tank connections
- Hydrant mains
- Fire department connection lines
- Large riser inlets

How to Choose?
- Set the sizeChoose the check valve for the line size.
- Confirm the flangeCheck that the mating flange is DIN PN16.
- Plan the orientationObserve the flow arrow and vertical installation limit.
- Assess the spaceConsider a wafer check valve if a short length is needed.
