The control valve can be furnished as an integral part of a mass flow controllers, a pressure controller, or as a separate component. It is a proportional, electro magnetic control valve with extremely fast and smooth flow control characteristics. With reference to the specific fields of application there are different series of unique Bronkhorst High-Tech control valves.
Pressure compensated bellow valves are direct acting control valves as the above mentioned F-001 series. They are also closed by spring force. A bellows compensates the closing force acting on the plunger to such a degree that only a very small magnetic force is required and in this way large orifices can be opened, which is impossible in the F-001 design as it would cause oscillation. The bellows pressure compensated design, however, enables us to smoothly control large flows at extremely low pressures.
