Designed for compatibility with all current halocarbon refrigerants, including CFCs, HCFCs and HFCs.
The SEI is an electronically operated 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.
SEI valves have an operating stroke of 0.125 inches and 1596 steps of control. Each step translates into 0.0000783 inches. When used with one of the Sporlan controllers, SEI valves yield unsurpassed accuracy in resolution of flow and repeatability of position.
SEI valves are suitable for liquid or hot gas bypass service
