White Rodgers EXV-M60 804665 EX4-EX8 Stepper Motor Driven Valves

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..

Features:

• 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
• Connector Cable for Stepper Motor Driven Electrical Control Valve
• Direct coupling of motor and valve for high reliability (no gear mechanism)
