GDR Series Gas Delivery Regulator
Brand: Generant Inc
The GDR Series Regulator provides reliable and precise pressure control in the most demanding applications.
Optimized spring design with unique Venturi design assures high flow with extremely low droop characteristics. Solid, non-tied diaphragm and all brass construction will provide leak-free and long-lasting performance.
Regulator is fully balanced to virtually eliminate outlet pressure fluctuations due to inlet pressure variations. All GDR Series regulators are 100% factory tested.
Features- Fully balanced design: Maintains a constant delivery pressure regardless of inlet pressure fluctuations
- Optimized for high flow: Unique Venturi tube and optimized spring design allows for high flow rates
- Wide pressure range: Inlet pressures up to psi: 550 (kPa: 3,792, bar: 37.92), outlet pressures up to psi: 450 (kPa: 3,103, bar: 31.03)
- Solid, non-tied, diaphragm: Solid diaphragm eliminates potential leak path and increases sensitivity
- Configurable: Order regulators with various porting options, panel-mounted, with chamber pipe-a-way, or pilot operated
- Oxygen service compatible: Designed for use in oxygen service and cleaned for use in O2 service standard
