Check Valve d50 with Teflon Spring PN10 PVC

The check valve with a diameter of d50 and a Teflon spring is the most commonly used size for the main circulation circuits of residential pools. It reliably prevents the backflow of water when the pump is switched off, thereby protecting the pump from running dry and preventing the pipework from emptying. The Teflon spring does not corrode and keeps the valve functional even after years of operation in chlorinated water.

The PVC-U body withstands all pool chemicals. The d50 socket is connected by gluing to standard pipework. The PN10 rating ensures reliable, leak-free operation even at higher pump pressure peaks. Suitable for all types of pool filtration with d50 main pipework.
