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 areas:

  • 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 1968 hand expansion valves are available in angle way and straight way versions

Internal PTFE back seating design to replace seal while the valve is still operating

Dual function- expansion and isolation

Non asbestos gaskets

Hand wheels are red in colour so as to distinguish these valves from shut off valves

Safe working pressure: 400 psig (27 bar)

Temperature range: -60oF Suitable for R717 (Ammonia), R744 (CO2), HCFC & HFC, to +240oF ( -51oC to +116oC)

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 designed 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 used to tighten bonnet give extra life to the valves

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

Suitable for R717 (Ammonia), R744 (CO2 ), HCFC & HFC, chemical and petrochemical applications

The full temperature range packing gland ensures perfect tightness in the whole temperature range
