Parker 70714 Valve Refrigerant you can tune the potentiometerThe Parker 70714 is a performance grade 3 4" GP657 solenoid valve engineered specifically for technical saturated steam service. Designed with a robust brass body and high resiliency EPT (ethylene propylene) diaphragm, this 2 way normally closed steam valve manages pressure differentials from 1 to 50 PSI. For veteran contractors, the stainless steel seat insert is a critical feature, mitigating the erosion typically seen in high velocity steam lines.
