Product Description

EMERSON EX4-EX8 Series Stepper Motor Driven Valves For Air Conditioning

The EX4-EX8 Series are bi-polar stepper motor driven valves 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 stainless steel design

• Fast full stroke time

• Ceramic slide and port for accurate flow and minimal wear

• 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)
