Overview
The Kunkle Valve 6283G is a Series 6000 direct-acting relief valve engineered for dependable overpressure control in industrial steam, air, and gas systems. Rated to 125 PSIG, this valve combines a full nozzle design with oversized side outlet and bronze/brass trim to deliver precise pressure regulation with minimal maintenance. Part of the Kunkle Series 6000—manufactured by Emerson—the 6283G meets ASME Section I and Section VIII codes and is suitable for boilers, generators, compressors, and pressure-containing vessels.
