WITT – High Pressure Float Regulator 
HR Series


WITT high-pressure float regulator HR is intended for the use in refrigerant plants to expand liquid refrigerant from the high-pressure to the low pressure side. It also prevents any gas from flowing through the regulator. The simple mechanical construction enables energy efficient operation,at the same time eliminating the necessity for complicated electrical controls.

In order to safeguard the compressors in the plant against liquid hammer there is no need for correct functioning of the various stop- and control valves when using WITT HR float regulator.

A high pressure receiver (collection receiver) is not required for high pressure control systems, if available, it can even have a disturbing effect.

The regulator does not require a differential pressure to open.
