Specification
Application
Automatic expansion valves (constant pressure valves) series
AEL are used in general refrigeration and for original
equipment.
For plants with single injected evaporators and without a
distributor, such as air conditioners, dehumidifiers, air driers,
water coolers or ice-making machines.

Installation
• The valves may be installed in any position.
• When soldering the valve, the valve body must not get
warmer than 100 °C.
• Remove plastic cap during soldering
• Constructive modifications at the valve are not allowed.
Adjustment
One complete revolution of the adjusting screw effects an
alternation of the evaporating pressure by approx. 0.8 bar.
Turning clockwise = Higher evaporation pressure
Turning
counterclockwise
= Lower evaporation pressure
