EH50 Series Full-Port 2-Way Solenoid Valve, 1/2″

The EH50 series is a full-port 2-way solenoid valve offering a wide range of solutions for diverse application needs. This pilot-operated valve is ideal for controlling high-pressure air water natural gas hydrogen nitrogen and other compatible gases or light liquids. Available in 1/2″ NPT connection it requires a minimum pressure differential of 6.9 bar between inlet and outlet for operation. The EH50 retains the benefits of the EH40 series but adds the option of an integrated check valve making it perfect for CNG equipment and applications whether using a single-line buffer or a 3-bank cascade filling scheme. The valve features a removable cartridge for easy maintenance. The ATEX-certified EH50 series is designed for use in hazardous environments.
