Dear Deepak Hello, Although not 100% sure about the specific operation, service details/processes involved; this item seems to be a three-way control valve with multi-directional preset flow control/ throttling capabilities.
The nature of process requires certain amount of flow at all times without starvation which is most probably managed/ensured utilyzing similar contol valve(s) as integral part of control strategy.
Hope this helps.
