Piston accumulator VA

for refrigeration circuitsfor air conditioning

Parker Type VA, PA, and VPA, series accumulators have a primary purpose to catch and hold any unused portion of the system charge. The device must also prevent liquid slugging of the compressor and excessive refrigerant dilution of the compressor oil. They must return refrigerant and oil to the compressor at a sufficient rate. Parker Type RT receivers provides a reservoir for refrigerant during operation of a refrigeration system. During normal operation, the receiver ensures availability of a reserve quantity of refrigerant during periods of high load demands and provides a place to store the refrigerant charge during pump down. Each is factory tested to ensure positive leak-free performance. Accumulator Features/Benefits: • Copper connections on most models • U-tube design for maximum flow and minimum oil entrapment • Inlet flow deflector to guide refrigerant toward wall for smooth flow and gradual expansion • Baffled U-tube entrance is positioned behind the inlet flow baffle • Metering orifice matched to system capacity • Integral 430 degrees F fuse plugs on larger models • Maximum working pressure for the VA and VPA models is 300 psi (20.7 bar) and PA models is 355 psi (24.5 bar) Receiver Features/Benefits: • Available ¼” – 5/8” ODF copper connections • Vertical and Horizontal models • PTFE gasket seal for valve • Receivers available with or without isolation valves • Integral 430 degrees F fuse plugs on larger models • Maximum working pressure for the RT series is 500 psi (35 bar),
