DBB Ball Valve
148 products found
A DBB ball valve (Double Block and Bleed) is a critical, high-integrity safety valve that integrates two distinct sealing surfaces and an independent center cavity bleed port into a single, compact body. Engineered to meet the strict mandates of the API 6D pipeline standard, this quarter-turn rotary valve utilizes dual unidirectional seats that automatically block pressure from both ends of the line simultaneously when closed. By opening the integral vent, operators can safely drain trapped cavity fluid to visually confirm absolute zero-leakage isolation before initiating downstream maintenance. Through our platform, we connect industrial buyers with leading ball valve manufacturers in China who supply high-performance DBB ball valves in both floating and trunnion-mounted designs, providing global pipeline operators with an extensive selection of verified, space-saving isolation solutions at competitive factory pricing.
