True Union Spring Check Valve – DS Series
Chemline DS Series PVC and CPVC True Union Spring Check valves have a PTFE covered stainless steel spring for positive closing. Compared to ball check valves, DS Series require very low liquid head pressure to close. That means more flexibility as to where valves may be placed in a piping system.
