Sporlan

Sporlan is a manufacturer of refrigerant controls and components for air conditioning, heat pump, and commercial refrigeration systems. Founded in 1934 in St. Louis, MO as the Spoehrer-Lange Company, Sporlan introduced the Catch-All in 1947, the world's first molded core filter drier. Parker Hannifin acquired Sporlan Valve Co. in October 2004; Sporlan now operates as a division within Parker Hannifin's Climate and Industrial Controls segment, based in Washington, Missouri.

How to Choose a Sporlan Component

TXV: match refrigerant type, system capacity, connection size, and equalizer configuration. Filter drier: select Catch-All size by system capacity and connection diameter; replace after compressor burnout or open-system event. Solenoid valve: normally-closed for liquid line; combined solenoid/check valve for heat pump reverse-cycle. Electronic expansion valve: SER for refrigeration, EDEV for AC/heat pump variable-capacity systems.
