EVR-GSD4 Vacuum Regulator

The EVR-GSD4 is a small vacuum regulator with 1/2″ ports.

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.

Meeting the challenges of vacuum holding applications

Vacuum technology is commonly used to hold objects in place for processing or positioning. Vacuum table, vacuum conveyor and vacuum pick-and-place operations are examples of this type of application. In most vacuum holding applications, flow rate and pressure vary significantly during start-up and when disruptions occur in the manufacturing process. While some vacuum applications are Read More
