The d32 check valve with a Teflon spring protects the pool pump and pipework system against water backflow when the unit is switched off. The d32 diameter matches the outlet pipework of many domestic pool pumps and filtration systems. The Teflon spring does not corrode even in an environment with chlorine or other disinfectants.
The valve body made of PVC-U is fully chemically resistant and requires no surface treatment. The glued d32 connection guarantees a permanently watertight joint. PN10 allows safe operation across the entire pressure range of a standard pool installation.
