The check valve with a diameter of d63 and a Teflon spring is intended for large pool installations where the main circulation pipe reaches a diameter of 63 mm and the flow rate exceeds 15 m³/h. The Teflon spring ensures reliable closing of the valve when the pump is shut down and prevents the backflow of water, which could cause air entering the pipework or damage to the pump. The PN10 classification is sufficient for all standard industrial and residential pool technologies.
The entire valve body made of PVC-U is resistant to chlorine, oxidants and the acids of pool chemistry. The glued d63 neck guarantees a permanent and firm mounting in the pipework system. Ideal for pools with a volume of over 80 m³ or systems with a counter-current and water features requiring a high flow rate.
