Parker SERI-KS Step Motor Electronic Expansion Valve

1. Advantage：

A chiller that has switched from a thermostatic expansion valve to a stepper-driven EEV is making a promise to the compressor: superheat will be held to a tight band across every load, not allowed to wander as ambient conditions change.

When the SERI valve starts mis-stepping or seats off-center, that promise breaks - suction pressure swings, the controller backs out the capacity, and the plant cools in short bursts instead of steadily. Fitting a TXV to a line the controller is stepping to 0-500 pulse positions throws away that loop entirely.

SERI-KS is the stepper valve that drops back into the same piping: the 1-1/8" inlet and 1-3/8" outlet ODF ends match the liquid and suction lines already brazed in, and the M12 connector mates to the existing harness so the controller keeps sending the same stepping pattern. Because the valve ships in the Parker box with the leaflet, the seat and the pin are not exposed to shop air before it reaches the job.

3.Our Advantage

Kairui Refrigeration supplies Parker, Sporlan, Danfoss and Castel expansion valves and electronic controls to service teams working on chillers and rooftop units already in the field. Each EEV leaves here in the manufacturer's box, the port sizes and the connector type on the label are read against the job before dispatch, and single valves ship in 15 days by express so the contractor is not waiting on a factory lead time while the chiller is down.
