Features
• Stainless steel power element eliminates corrosion
and prevents valve failure
• Hermetic, leak-free construction
• Compact size allows installation in limited spaces
• Bi-Flow capability allows one valve to control the
superheat in both cooling and heating modes for
heat pump applications
• Balanced port construction compensates for
changes in operating pressures due to varying
ambients, gas defrost, heat reclaim, or widely
varying evaporator loads
The BA/BN series is a balanced ported valve. Typical applications
include: refrigerated cases, coolers, freezers, ice machines and air
conditioning systems. BA/BN valves operate over widely varying
operating conditions.
Options
• ZW195 charge available for R-410A systems
• External or internal equalizer
• Bleed type pressure equalization available to
accommodate PSC type compressors
• SAE or ODF connections standard – Chatleff or Aeroquip
are available
• Adjustable or non-adjustable superheat
Specifications
• Maximum working pressure: 700 psig
