By providing synchronized signals to the step motor, discrete angular movements are translated through a Digital Linear Actuator (DLA) into precise linear positioning of the valve piston. The Subcool Control provides liquid temperature and superheat (pressure-temperature) control for most common refrigerants. FREE Shipping on eligible orders. Control algorithms for the valve include a initialization sequence that will first over-drive the valve in the closing direction.
The properly applied CDS valve and controller can replace standard mechanical evaporator pressure regulators (EPR), suction stop solenoid valves, and conventional thermostats.
Sporlan thermal expansion valve 1. The ESR-valve has 8total steps. The Einstein controller is configured with the Emerson valve as the default. The conversion kit reduces valve complexity and external seal surface area. Applications include Evap. CDS valves are suited for a wide range of suction, liquid and discharge line applications due to their broad fluid temperature range.
CDS -and -are suitable for these applications as supplied. Due to the step motor design, the CDS series are the first evaporator control valves that may be sized to contribute NO additional pressure drop to the suction line.
