Features
• Stainless steel power element eliminates corrosion and
prevents valve failure
• Hermetic, leak-free construction
• Compact size allows installation in limited spaces
• Mass spectrometer tested to ensure less than 0.10 oz/year
external leakage rate
A-Series
Specifications
Maximum working pressure: 700 psig
UL/CUL le number: SA 5312
The A-series is used for heat pump, air conditioning, food services
and commercial applications.
Options
• ZW195 charge available for R-410A systems
• Adjustable or non-adjustable superheat
• SAE or ODF connections standard – Chatleff or Aeroquip
are available
• External or internal equalizer
• Internal check valve allows reverse ow for heat
pump applications, eliminating the need for external piping
and external check valve
• Bleed type pressure equalization to accommodate
PSC type compressors
• Pressure limiting charges (MOP) available
