Designed for compatibility with all current halocarbon refrigerants, including CFCs, HCFCs and HFCs. For air conditioning and heat pump uni-directional applications only!! The ESX is an electronically operated, unipolar step motor flow control valve, intended for the precise control of liquid refrigerant flow. Synchronized signals to the motor provide discrete angular movement, which is translated into precise linear positioning of the valve pin. Valve pins and ports are uniquely characterized to provide improved flow resolution and performance. ESX valves have an operating stroke of 0.104 inches and 500 steps of control. Each step translates into 0.0002 inches. When used with one of the Sporlan controllers, ESX valves yield unsurpassed accuracy in resolution of flow and repeatability of position.
