Learn more about how Equilibar® vacuum regulators work.
Equilibar EVR is a Direct vacuum regulator
The Equilibar® vacuum regulator directly controls vacuum pressure by throttling flow between the vacuum supply pump and the process in order to precisely control the process vacuum to a specific setpoint. The EVR is a non-relieving regulator intended for processes where at least a very small gas flow is present at all times.
If your process is gas-tight, an Equilibar application engineer can discuss easy methods of providing a small gas bleed in the process.
Equilibar EVR is NOT a Vacuum Breaker
Equilibar vacuum regulators are not vacuum breakers, which let gas into the system to control pressure.

Dramatic Stability Improvement
The Equilibar EVR holds vacuum pressure stable across varying supply pressures. Traditional vacuum regulators are often sensitive to vacuum supply pressure, whereas Equilibar vacuum regulators effectively isolate upstream pressure from varying supply. This chart shows the excellent flow stability of the 1″ Equilibar® EVR.
Selecting the right size
Installing the Equilibar® Vacuum Regulator
To install an Equilibar vacuum regulator, simply connect your vacuum supply pump or to the Outlet port. Connect the process that you want to control to the Inlet port. Ensure there is a small amount of gas bleed into the system. Start the system and adjust vacuum pilot regulator knob to achieve the desired vacuum level.
Vacuum Regulator Video
The video below shows a vacuum regulator with a smaller body size that is designed for vacuum systems with lower maximum flow rates. These small size vacuum regulators exhibit high precision for accurate control. The video shows how the vacuum control valve may be manually adjusted or controlled with an electronic vacuum regulator.
High Flow Vacuum Regulator Video
The link to this video shows how the Equilibar direct diaphragm sealing technology may be scaled up into larger sized vacuum regulators for high flow systems. The BD Series of vacuum regulator shown in the video is available in sizes from 1.5 inch to 4 inch in flange connection or with NPT threads. The HV Series (not shown) vacuum control valves are available in 2, 4, and 6 inch sizes. Click here to go to YouTube and watch the high flow vacuum control valve video
