The check valve of the S6 series with a steel spring for a d40 diameter protects pumps and other pool technology components from the back pressure of water. The closing mechanism with a stainless steel spring reacts instantly when the flow drops.
The PVC-U body is resistant to chlorine, bromine disinfection and other pool chemicals. The valve is designed for installation by solvent welding into existing pipework.
Check valves are indispensable especially downstream of chemical dosing pumps, in solar circuits and in pumping stations with variable load. A correctly installed valve extends the service life of the entire filtration system.
