EH40-08 – 1/2" NPT Full Port (Normally Closed)
Features
Our new EH40-08 is a versatile, ½” full port, high pressure, pilot operated, solenoid valve. Its improvements over our current EH50 include a more compact size, for where space is limited, and a higher pressure range with direct current (DC) power. The compact EH40-08 is ideal for flow control of high pressure air, water, compressed natural gas (CNG), hydrogen, nitrogen, and other gases or light liquids compatible with the materials of construction, and leverages this high pressure flow to its own advantage in operating effectively and efficiently.
Applications
Our new compact EH40-08 style valve is perfect for use in hydrogen dispensing tanks, commonly used in the refueling of fleet vehicles. It is also a used in many compressed natural gas applications. With available pressures to 10,000 psig there are a wide range of applications that include water, nitrogen and many other compatible liquids. This solenoid valve must be mounted with the solenoid upright and vertical.
