The d25 check valve with a Teflon spring is the medium size in the range and is well suited to installations with small branches of pool pipework or chemical dosing circuits. The Teflon spring guarantees reliable closing even in an aggressive chemical environment and does not corrode even after years of operation. The PN10 classification ensures safe operation at standard pool working pressures.
The entire valve is made of PVC-U and is connected by gluing to d25 pipework. The compact design reduces the space requirements for installation in a manifold. Ideal for custom installations combining filtration technology with automatic chemical dosing.
