Sporlan SERI-J Expansion Valve

Trane VAL11996 Expansion Valve (X15111285160)

The SER(I) series valves are step motor electric 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.
