Equilibar Vacuum Pilot Regulator
Vacuum pilot regulator
The dome is pressurized by the vacuum pressure above the diaphragm, and the inlet vacuum pressure is controlled to be almost equal to this "pilot vacuum pressure." The pilot vacuum pressure on the dome can be adjusted using a manual or electronic vacuum regulator and can operate in either an open-loop or closed-loop control system. The choice of vacuum pilot control method depends on the performance requirements of the application. Note: The Equilibar EVR is designed to withstand harsh chemical conditions, but our vacuum pilot regulators and fittings are not. The flow through the vacuum pilot moves from atmospheric pressure toward the inlet of the vacuum supply pump, so during normal operation, chemicals do not flow into the vacuum pilot. There is always a small amount of leakage from the vacuum pilot regulator. For more details, please refer to the bottom of the safety design page. If you are using harsh chemicals, please consult with an application engineer.
