Metal Sealed Pressure Controllers

Stable pressure control and enhanced process gas purity. Maximized process results.

Metal sealed pressure controllers from Brooks Instrument are designed to be reliable and durable while delivering the sustained and proven accuracy users worldwide count on from the leader in fluid measurement and control. Our electronic pressure controllers utilize the core control technology present in our industry-leading thermal mass flow controllers.

Electronic pressure controllers eliminate the droop and hysteresis associated with traditional mechanical spring diaphragm pressure regulators. And, choosing a metal sealed pressure controller brings enhanced purity of the gas due to elimination of oxygen permeation through elastomers, with a reduction in maintenance since metal seals will last indefinitely.

Brooks pressure controllers are available with internal pressure sensors to control pressure in a range from torr to 500 psig. The result: pressure controllers that keep critical semiconductor processes on-target and under the most stringent control – hour after hour, day in and day out.
