Vacuum Regulators and Vacuum Control Valves
UNIQUE VACUUM REGULATOR DESIGN FOR IMPROVED ACCURACY
Like our unique back pressure regulator technology, the Equilibar® vacuum regulator (EVR) uses multiple orifices sealed by a flexible diaphragm instead of a single large valve seat. The Equilibar is dome-loaded by a pilot regulator setting the vacuum setpoint. As flow requirements change, the diaphragm moves a few millimeters to open and close over some or all of the orifices, providing instantaneous and frictionless control. The pilot setpoint pressure may be set with a manual or electronic vacuum pilot regulator.
EVR is available in sizes from 1/4″ to 4″ ports. Starting at $600, they offer a good option for complex vacuum applications where conventional solutions have not worked.

How to choose a vacuum pilot regulator
The pilot vacuum pressure on the dome may be regulated using a manual or an electronic vacuum regulator and may be operated in open loop or closed loop control schemes. The vacuum pilot control choice depends on the application performance requirements. While all of the choices have continuous air ingestion from atmosphere, they vary in intake rate. Read more about various types and specifications of vacuum pilot regulators to control the EVR vacuum pressure.
Equilibar EVR is a Direct vacuum regulator
The EVR 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.
