SEH-P ELECTRIC EXPANSION VALVE

Sporlan is pleased to introduce the SEH-P, the newest
addition to the family of large Electric Expansion Valves,
and the largest valve approved for air-cooled R-410A
applications. Featuring a straight through configuration,
this EEV provides an alternative to the existing angle 5.61”
(1.43 mm)
configuration of the SEHI-400. Contact your local Sales
Engineer for assistance with sizing a Sporlan EEV for your 0.91”
(23 mm) 1.813” (46 mm) HEX
application, or selecting a suitable controller to optimize
your system’s performance.
