BA / BN Series Expansion Valves

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.

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
• 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
• Maximum working pressure: 700 psig

AMI COLOR CHANGE LABEL

In an effort to standardize product appearance and capabilities, Emerson Climate Technologies Flow Controls is implementing a change to the color change label that affects the appearance but not performance of the AMI moisture indicating sightglass. The label has been changed from the 4 color label ( dark blue-dry, purple-dry/caution, pink-caution/wet, orange-wet) to the same 3 color label as the HMI moisture indicating sightglass (dark blue-dry, purple-caution, pale orange-wet). Please see the photos below that illustrate the change.

The ability of the moisture indicator has not changed and remains the most sensitive moisture indicator in the industry. In order to make the indicator easier to use, caution/wet pink color was removed. This indicator label still provides an intermediate color, caution, than competitive moisture indicators and so provides greater information to the service technician.

Because one color was removed, the sensitivity table has been modified. The table now is the same as the HMI, Emerson hermetic moisture indicator.

Criteria For Refrigerant Selection

In the air conditioning and refrigeration industry, virtually all of the refrigerant experience has been limited to single-component (“pure”) refrigerants; however, as we search for acceptable replacements for these compounds, refrigerant manufacturers have been unsuccessful in developing single-component replacements that meet all of the required or highly desirable characteristics for a widely used refrigerant.

These requirements include:

Environmental acceptability

Chemical stability.....

Refrigeration Pressure Regulators

Basic Applications:

• upstream evaporator pressure regulator
• downstream crankcase pressure regulator
• condensing pressure regulator
  
• hot gas bypass
• head pressure control
• capacity control
  
• stepper motor diagnostic

Selection of Solenoid Valves for DC applications

Attention to electrical characteristics is important in refrigeration solenoid valves. Required voltage and frequency must be specified to ensure proper selection. Valves for DC services often have different internal construction than valves for AC application, so it is important to study the manufacturer's catalog information carefully. If unsure and you require technical assistance, contact your local Emerson Flow Controls wholesale specialists immediately.
