Top DBB Ball Valve Manufacturers and Suppliers in Canada

In the demanding industries of oil, gas, and fluid process control, Double Block and Bleed (DBB) ball valves play a crucial role in maintaining safety, operational integrity, and efficiency. DBB ball valves incorporate two isolation valves within one valve body, combined with a bleed valve that safely vents pressure or fluid that may be trapped in the cavity, providing a fail-safe method for isolating pipelines or process equipment. The compact design not only reduces potential leak points but also lowers maintenance complexity and cost.

Our company, a dedicated Chinese manufacturer specializing in the design, development, and production of high-quality ball valves—including floating ball valves, trunnion ball valves, and top-entry ball valves—offers premium DBB ball valve solutions with extensive OEM services. Our valves serve significant sectors such as upstream, midstream, and downstream oil and gas, seawater desalination plants, and offshore drilling platforms. This article explores leading DBB ball valve manufacturers and suppliers in Canada, their product capabilities, and how our offerings align with market demands.

Understanding DBB Ball Valves

A Double Block and Bleed ball valve is an integrated valve that combines two independent sealing elements with a bleed valve positioned between them. The two block valves act as barriers to isolate fluid upstream and downstream, and the bleed valve is used to vent or drain any trapped fluid or pressure found between the two seats. This arrangement ensures double isolation and double sealing, significantly reducing risk of leakage or cross-contamination, critical in hazardous or high-pressure systems.

DBB valves come primarily in two main types: floating ball and trunnion-mounted ball. Floating ball valves have the ball held in place by the seats, allowing slight movement to seal tightly, best suited for moderate pressures. Trunnion-mounted ball valves have the ball fixed on a trunnion shaft, which supports the ball and takes the operational load, preferred for larger sizes and high-pressure conditions. Both types guarantee quarter-turn operation for quick open/close actuation and offer full port flow capabilities to minimize pressure drop.

The compact, single-body design of DBB valves makes them ideal for applications with limited space while maintaining rigorous safety and performance standards. The bleed valve's inclusion allows operators to verify successful isolation by venting pressure before maintenance or repair work.
