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 outlet pressure fluctuations due to inlet pressure variations. All GDR Series regulators are 100% factory tested.

Note:
    * Pilot Operated Regulators fail closed on loss of pilot pressure.  Regulators fail open on loss of outlet pressure when pilot pressure is present.
    * All Regulators are supplied with 2 (two) 1/4" NPT Pipe Plugs.  Pipe plugs are supplied finger tight.
    * Final installation is the responsibility of the end user.
