The EVR-GSD4 is a small vacuum regulator with 1/2″ ports. This size EVR-GS vacuum regulator would be useful in vacuum table or vacuum holding applications where high precision and fast response are important.
EVR-GS Vacuum Regulator Series
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. Like our unique back pressure regulator technology, instead of a single large valve seat 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.
