Specification
Application
Hot gas bypass valves series CVC and HLE are used to
adjust the compressor capacity to the actual evaporator
capacity in a refrigerating plant.
The hot gas bypass valve can be installed in a bypass tube
between the hot gas line and suction line. The suction
pressure is downward limited by flowing hot gas from the high
pressure to the low pressure side.
For plants in general refrigeration and for original equipment
such as 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 suction pressure limitation by approx.
0.5 bar (CVC) resp. 0.4 bar (HLE).
Turning clockwise = Higher suction pressure
Turning
counterclockwise
= Lower suction pressure
