Controlling chemical vacuum processes with direct sealing diaphragm valves
The use of vacuum technology for chemical processes has increased dramatically in recent years. Due to the hazards involved with corrosive chemicals, process components must be chemically compatible, as well as extraordinarily accurate and precise. Traditional methods of controlling vacuum are not always suitable, and alternatives–including direct sealing diaphragm valves– must be considered.

A dose of precision
To address a flow-control problem that was preventing consistent dosing for water sanitation, a municipal water supply system determined that an Equilibar regulator could both stabilize and expand the range of control. Equilibar BPRs incorporate a dome-loaded design and use dozens of parallel orifices sealing on a supple diaphragm to better maintain pressure stability.
