Electronic Expansion Valve
Introduction
Designed for direct expansion refrigeration, air conditioning and chiller systems; Sporlan SER(I) valves precisely meter refrigerant and provide superior superheat control.
Parker-Sporlan’s SER(I) valves are stepper motor actuated electric expansion valves intended for use in direct expansion refrigeration and air conditioning applications. The SER valve is suited for a wide range of applications due to its compatibility with HCFC, HFC, HFO and HC refrigerants and Mineral, Alkylbenzene and Polyolester Oils.
The SERI product is also offered with an integrated sightglass for viewing refrigerant flow for troubleshooting. The valve is serviceable so the pin and port can be cleaned and the motor assembly replaced if needed. Both angled and straight configuration are offered for most models.
