The SER(K) series valves are step motor Electronic Expansion Valves. Step motors provide discrete segments of angular motion, or rotation, in response to an electronically generated signal. The advantages of step motors in valve applications are high resolution, repeatability and reliability with low hysteresis. Feedback loops not required, simplifying controller design and circuitry.

Installation

The SERI-K series valves are electronically controlled Step Motor Expansion Valves. These valves installed before the distributor and evaporator. And just as one would install a thermostatic expansion valve. The valves are bi-directional and used on heat pumps. Although the SERI-K and -L will have reduced flow in the reverse direction. Use proper location to provide serviceability. And to allow controller installation within the maximum cable length of forty feet. It is possible to install the valve in the refrigerated space. Therefore, mounting in any position except with the motor housing below horizontal line is possible. Furthermore, the cable routing should avoid any sharp edges or other sources of potential physical damage such as defrost heaters and fan blades. For neatness and protection, fastened the cable to the suction or liquid lines with nylon wire ties.
