KWT pump non-return valves prevent backflow trough the pumps when disabled. KWT pump valves are made from durable HDPE (density 0,96); the floating or closing balance is leveled trough extra weight, therefor a low opening pressure is made possible. Preventing energy loss for the pumps over the flap valves.
Between the flap and valve housing there is a EPDM lip sealing and trough the 15 degree angle position of the valve makes a solid static sealing. HDPE valves are light weight, easy to install and are very responsive and reliable, and in case of extra needed reliability there is an option for full stainless steel.
- Stainless steel is also available in a EUROCODE (CC / EXC) class.
- All KWT pumpvalves are made to order or designed to order.
- KWT produces valves up from Ø600mm oval, for optimal flow conditions!
