pressure relief valve

Equilibar EVR Vacuum Regulators are especially well suited for the complex demands of glovebox pressure control and are capable of controlling vacuum pressure in a glovebox down to the range of 1 inH2O (2 mbar). One of Equilibar’s glovebox applications was featured in the November 2017 Flow Control Magazine. In many glovebox situations, it is desirable to control pressure differential in order to improve dexterity of the operator’s gloves. At the same time, however, it is important to provide for stronger vacuum supply in the event of a compromised glove or opened hatch. A vacuum regulator can restrict the flow to the vacuum fan during normal operations and provide a surge of flow when needed to maintain pressure.
