“SUPER 1968” hand expansion valves are ideal for metering or flashing expansion of liquid refrigerant.
Liquid feed or circulating liquid feed evaporators
High pressure or intermediate pressure liquid feed to accumulators
intercoolers or recirculators
Defrost condensate relief
“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.
