Fisher control valve ES
Easy-e® ES and EAS general-purpose control valves are used for throttling or on-off control of a wide variety of clean liquids and gases. Both valve designs have single ports, unbalanced valve plugs, and cage guiding. In both designs, metal-to-metal seating is standard for all general applications over a wide range of pressure drops and temperatures. Metal-to-PTFE seating is optional for more stringent shutoff requirements.
