EH70 Series Cryogenic High-Pressure Solenoid Valve, 1/2“ – 2” NPT, 0 – 100 bar

The EH70 series is a powerful, full-port 2/2-way pilot-operated solenoid valve suitable for a wide range of temperatures, fluids, and gases. It is particularly well-suited for natural gas applications in hazardous locations and cryogenic conditions. With orifice sizes ranging from 1/2″ to 2″ and a maximum inlet pressure of up to 103 bar, the valve requires no minimum pressure to open. The 1/2″ and 3/4″ sizes can be mounted in any orientation. The valve is available in normally closed (NC) and normally open (NO) configurations and is CRN certified for all Canadian provinces.
