When refrigeration systems are exposed to low ambient conditions, the condensing pressure (head pressure) will fall. If the head pressure gets too low, the metering device will not have enough ...

This article deals with low ambient head pressure controls containing charged domes. Their function is to keep a proper condensing pressure at the metering device for proper feeding of the evaporator.

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

When the tank's internal bladder or diaphragm wears out, it can no longer regulate water pressure effectively. The HelloNation article explains that a failing pressure tank may cause water to run in ...

IMI has been selected to supply specialist control valves for ultra-high-pressure injection systems supporting a major ...
