Alco Controls for Maneurope Compressors

EX Series Electrical Control Valves

EX4 / EX5 / EX6 / EX7 / EX8 are stepper motor driven valves for precise control of refrigerant mass flow in air conditioning, refrigeration, heat pumps, close control, and industrial process cooling applications.

The Control Valves can be used as thermo-expansion duty, liquid injection duty, hot gas bypass, evaporator pressure regulator, crankcase pressure regulator, head pressure
regulator, or liquid level control. This data sheet describes only the performance of the valves.

Features
• Multifunction as expansion valves, hot gas bypass, suction gas throttling, head pressure, liquid level actuator etc.
• Fully hermetic design (no thread joints between valve body and motor compartment)
• Applicable to all common refrigerants (HCFC, HFC) and for subcritical CO2 applications
• Stepper motor driven
• Short opening and closing time
• Very fast full stroke time
• High resolution and excellent repeatability
• Bi-flow versions for heat pump applications
• Positive shut-off function to eliminate the use of an additional solenoid valve
• Linear flow capacity
• Extremely wide capacity range (10 … 100%)
• Continuous modulation of mass flow, no stress (liquid hammering) in the refrigeration circuit
• Direct coupling of motor and valve for high reliability (no gear mechanism)
• Ceramic slide and port for accurate flow and minimal wear
• Balanced force design
• Corrosion resistant stainless steel body and stainless steel connections

An awful effect of a fake filter drier.

The supermarket refrigeration system suffered because fake filter driers were used. Several call backs, money and time wasted as a result.

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
