Hand Expansion, Needle and Regulating Valves for Ammonia (R717)

About Hand Expansion, Needle and Regulating Valves for Ammonia (R717)

SUPER 1968 hand expansion, needle and regulating valves are used for metering or flashing expansion of liquid refrigerant in ammonia (R717) plants: liquid feed or circulating liquid feed evaporators, high- or intermediate-pressure liquid feed to accumulators, intercoolers or recirculators, and defrost condensate relief. The family covers screwed, flanged, Y-type and cast-steel weldable versions. Manufactured by the SUPER group; machined in-house at our Sonipat CNC plant.
