EVR Series Regulators
Like our unique back pressure regulator, the Equilibar vacuum regulator uses multiple orifices sealed by a flexible diaphragm. 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 pilot regulator.
Our vacuum regulators are available in sizes from 1/4″ to 4″ ports.
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.
The EVR is 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.
