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.
Pilot-operated valves are patented indirect acting control valves suitable for high flow rates, up to 500 m3n/h N2-equivalent. They use a complete Vary-P valve as described above, as pilot valve. Hence they are also pressure compensated. The pilot controls the pressure on the back side of a spring loaded cylinder, of which the front side is subject to the inlet pressure of the main valve. This cylinder furnishes the power for the main valve. As soon as the delta-P becomes bigger than the spring force, the main valve, will open.
