The EH50 Series

High Pressure Solenoid Valve - EH50 Series High Pressure Solenoid Valve – EH50 Section Rendering High Pressure Solenoid Valve – EH50 Renderingg

Features:

The full port EH50 offers a wide range of solutions for your application needs, and is best used to control the flow of high pressure air, water, natural gas, hydrogen, nitrogen and other gases or light liquids compatible with materials of construction. This pilot operated valve is a great choice for differential pressures as high as 10,000 PSI. The valve comes in a ½” NPT connection size and requires a 100 PSIG minimum pressure differential between inlet and outlet for operation. The EH50 offers many of the benefits of our EH40, but with the available option of an integrated check valve. The EH50 is an ideal choice for CNG equipment and applications, whether your system utilizes a single-line buffer or a 3-bank cascade filling scheme. The valve also features a cartridge that can be easily removed for maintenance. The Normally Closed EH50 valves must be mounted upright and vertical, while the Normally Open EH50 valves are universal mount. Filters are recommended for all applications.
