EX7-U31, EX4-EX8 Series Stepper Motor Driven Valves

Référence : 800626

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..

Caractéristiques

Fully hermetic design
Fast full stroke time
Applicable to all common refrigerants (HCFC, HFC), for subcritical R-744 applications
High resolution and excellent repeatability
Bi-directional versions for heat pump applications
Positive shut-off function to eliminate the use of an additional solenoid valve
Linear flow capacity
Wide capacity range (10 - 100%)
Continuous modulation of mass flow, no stress (liquid hammering) in the refrigeration circuit
Direct coupling of motor and valve for high reliability (no gear mechanism)
