Series GDR
Gas Delivery Regulator

Description

The GDR Series Regulator provides reliable, precise pressure control in the most demanding applications. Optimized venturi and spring design assures high flow with extremely low droop characteristics. Solid non-tied diaphragm and all brass construction guarantees leak free long lasting performance. Fully balanced design virtually eliminates delivery pressure fluctuations due to inlet pressure variations. All GDR Series regulators are 100% factory tested, cleaned and packaged for oxygen service.
