For use in eliminating siphoning when feeding at negative pressure. These rugged valves are constructed from machined components to ensure long life and reliability. The spring loaded PTFE faced diaphragms provide positive discharge pressure to stabilize pump output and prevent syphoning. All valves are screw adjustable from 0 to 150 psi. These valves are ideal for LK and EHE metering pumps, but can be used with any metering pump requiring back pressure adjustment or anti-syphon protection.
