API Spec 600 is for Bolted Bonnet Steel Gate Valves for the Petroleum and Natural Gas Industries. API 600 addresses the design, materials, testing, inspection and examination of valves. API Spec 600 is an International standard that specifies the requirements for heavy-duty bolted bonnet steel gate valves for petroleum refinery and related applications where corrosion, erosion and other service conditions would indicate a need for full port openings, heavy wall sections and large stem diameters.
Flow and Control Engineering offers several valves that are designed and tested in accordance with the API 600 Spec:
Walworth Cast Steel Gate Valves – 2″ to 72″, 150#-2500#, RF, RTJ or BW. WALWORTH always keeps these valves in stock in the most common trims used in the industries. This product line is manufactured as per API-600 design requirements for gate valves.
