 Refrigerant valve MVL661..-.. for capacity control of a chiller.
- Typical control range 10 to 100%.
- Energy-efficient operation with low loads.
- Allows wide adjustment of condensing and evaporating temperatures.
- Ideal for use with plate heat exchangers.
- Very high degree of frost protection.

NOTE: A larger valve may be required for low load operation than is needed for full
load conditions. To ensure that the selected valve will not be too small for low
loads, sizing should take both possibilities into account.
