The 6000 series Kunkle valves are popular with air, gas and steam applications. Valve housing is a heavy duty casting. These bronze and stainless steel valves are used with steam boilers, steam generators, air compressors, gas compressors – both reciprocating and rotary, intercoolers and aftercoolers, pressurized steam autoclaves, pressurized steam sterilizers, and pressure reducing stations. Model variations allow for more customized applications.
