The EH30 Series

High Pressure Solenoid Valve - EH30 Series High Pressure Solenoid Valve - EH30 Section Rendering High Pressure Solenoid Valve - EH30 Rendering


The EH30 is great for a wide range of pressures and many different fluids and gases. This direct acting valve offers a solution to a variety of applications to control the flow of high pressure air, water, hydrogen, nitrogen and other gases or light liquids compatible with materials of construction. Suitable for cryogenic applications, this low flow, high pressure valve packages great versatility in a compact design for pressures up to 10,000 PSIG. No minimum pressure is required for opening, and it will not “burp” due to any rapid spikes in inlet pressure. Both the Normally Closed and Normally Open versions can be universally mounted, as a standard. They both may be mounted in any orientation. Filters are recommended for all applications.
