Features:

The powerful, full port EH70 is great for a wide range of flow rates, temperatures, and a wide range of fluids and gases. It has become a popular choice for cryogenic conditions and applications that need to control higher pressures in a hazardous location. This pilot assisted, direct operated valve utilizes a UL/CSA certified enclosure for all hazardous locations, is available in larger pipe sizes (up to 2”) and for inlet pressures up to 1,500 PSIG. The versatile EH70 requires no minimum pressure for opening, and for up through to the 1" sizes, can be mounted in any orientation. (Normally Closed and Normally Open). This valve is CRN certified with all Canadian provinces. Other uses of the EH70 include controlling the flow of deionized water, condensate, ammonias, vegetable oils, fuel oils, hydrogen, cryogenics, flammable liquids and gases and other gases or liquids compatible with materials of construction. Filters are recommended for all applications.
