Electronic expansion valve FP-ERV+orifice (0-8)
The FP-ERV electronic expansion valves are electrically actuated, designed for the refrigeration and air conditioning system.
The electronic expansion valves are controlled by the refrigeration controller FP-MC-23EM. Valve capacity ranges from 1 to 16.3 kW (R22) and designated by orifice (FP-ERV-1 to FP-ERV-6).
The electronic expansion valve is designed to inject refrigerant into the evaporators of refrigeration units and shut off the liquid lines like a solenoid valve. The valve is operated by an electric actuator. The valve is controlled by the FP-MC-23EM refrigeration system controller via an alternating duty cycle PWM signal. HFC, CFC, HCFC refrigerants can be used as working medium. The number that gives an idea of the performance is included in the type designation. This number indicates the nozzle insertion number. The knotted nozzle insert is replaceable
