COMPONENTS

Fully hermetic designFast full stroke timeApplicable to all common refrigerants (HCFC, HFC), for subcritical CO2 applicationsHigh resolution and excellent repeatabilityBi-directional versions for heat pump applicationsPositive shut-off function to eliminate the use of an additional solenoid valveLinear flow capacityWide capacity range (10 – 100%)Continuous modulation of mass flow, no stress (liquid hammering) in the refrigeration circuitDirect coupling of motor and valve for high reliability (no gear mechanism) The EX4-EX8 are stepper motor driven valves that are optimized for the control of liquid or gaseous mass flow in refrigeration systems.. Multifunction capability as expansion valve, hot gas bypass, suction gas throttling, head pressure, liquid line actuator and other applications systems..
