Hand Expansion/ Needle/ Regulating Valves

Hand Expansion/ Needle/ Regulating  Valves

“SUPER 1968” hand expansion valves are ideal for metering or flashing expansion of liquid refrigerant.

Application- 

Liquid feed or circulating liquid feed evaporators

High pressure or intermediate pressure liquid feed to accumulators

intercoolers or recirculators

Defrost condensate relief 

Features and Benefits

  • “SUPER” Hand expansion are available in angle way and straight way versions.

  • Dual function- Expansion and isolation.

  • Non asbestos gaskets.

  • Hand wheels are of red colour to distinguish them from shut off valves.

  • Safe working pressure 400 psig (27 bar)

  • Temperature range: -60° F to +240° F ( -51° F to +116° F )

  • Extended neck provides greater insulation clearance

  • Individual pressure testing of each valve

  • All components are manufactured on CNC machines

  • Can be used as stop valve in closed position

  • Designed to achieve precise flow regulation

  • The valve is design to withstand high internal pressure. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion

  • High tensile bolts to tighten bonnet give extra life to the valves

  • All valves are painted with premium quality paint that protect valves in all weather conditions

  • Suitable for R717 (Ammonia) ,R744(CO2), HCFC & HFC, Chemical and petrochemical applications.
