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.
