The check valve of 20 mm diameter is made of durable PVC-U with an AISI 302 stainless steel spring and an EPDM seal – materials that withstand the chemical environment of pool pipework over the long term.
The valve reliably prevents backflow of the medium, thereby protecting the pump from cavitation on start-up and preventing unwanted draining of the pipework. The operating pressure reaches 16 bar at 20 °C and 10 bar at 40 °C.
The product comes from a proven Portuguese manufacturer and, thanks to its high build quality, offers a long service life without the need to replace sealing elements.
