The check valve with a diameter of d40 and a Teflon spring is suitable for medium-performance pool installations, where the d40 pipe diameter ensures sufficient flow without excessive hydraulic losses. The Teflon spring reliably closes the valve at any drop in pressure or pump stoppage. PN10 allows safe operation across the entire range of pressure conditions found in standard pool equipment.
The PVC-U material withstands the aggressive pool environment without degradation throughout the entire service life of the installation. The glued d40 socket ensures a firm, watertight joint. The valve is suitable for all types of pool technology where backflow must be prevented when the pump is shut down.
