Brisbane, Canberra, Darwin, Hobart, Melbourne, Perth, and Sydney are among the cities we service. A type of valve called a Double Block and Bleed (DBB) Ball Valve is made to have two separate sealing sites inside of the same valve body. This makes sure that the fluid or gas being delivered is kept separate from both the surroundings and the pipework downstream. The two seals guard against fluid or gas seeping out of the valve and are commonly composed of metal or a thermoplastic substance. A bleed valve is also incorporated into the design to enable pressure testing or valve venting. The DBB's ball valve component makes it an effective choice for situations where isolation and control of fluid flow are required since it makes it simple and quick to shut off flow in pipelines.
Australian Valve is the best Double Block And Bleed Ball Valve Manufacturer in Australia. We use superior quality materials and our valves are durable and reliable. In many industrial applications where fluid flow control and operator safety are of the highest concern, Double Block and Bleed ball valves are crucial components.

• Parts
 Valve body
 Ball
 Stem
 Sealing elements
 Actuator
 Bleed valve
 Gaskets and O-rings

• Advantages
 It is ensured that the fluid or gas being transferred is separated from the environment and downstream pipes by the two independent sealing points found within the valve body.
 The bleed valve enables pressure testing or valve venting, protecting people and machinery during maintenance or other activities.
 The DBB is an effective choice for situations where isolation and control of fluid flow are required because the ball valve component of the DBB enables simple and rapid shut-off of flow in pipelines.
 The DBB is made of materials like metal and thermoplastic that are generally dependable and corrosion-resistant, assuring long-lasting performance and dependability.
 Due to its availability in a variety of sizes and materials, DBB ball valves are suited for a variety of applications involving various fluid or gas types.
 The DBB is intended to fulfil industry standards and regulations, such as API 6D and ISO 14313, guaranteeing that it is acceptable for use in critical applications and environments. The design of the DBB makes maintenance and repair simple, lowering the overall cost of ownership and downtime.

• Applications
• Oil and gas pipelines: Double isolation points for pipeline maintenance and repair are provided by DBB ball valves, which are widely utilised in the oil and gas sector. They are utilised to stop fluid flow in both directions during pigging, maintenance, and shutdown procedures.
• Chemical processing: In chemical processing plants, DBB ball valves are used to segregate and regulate the flow of different chemicals and fluids, including acids, bases, and solvents. They add an additional layer of defence against contamination and leakage.
• Petrochemical processing: In petrochemical processing plants, DBB ball valves are used to segregate and regulate the flow of different chemicals and fluids, including crude oil, gasoline, and diesel fuel. To stop leaks and guarantee safe operation, they are utilised in storage tanks, pipelines, and processing facilities.
• Water treatment facilities: To segregate and regulate the flow of water and other fluids, water treatment facilities employ DBB ball valves. They are utilised for both emergency shutdowns and maintenance and repair work.
• Pharmaceutical manufacturing: To segregate and regulate the flow of different chemicals and fluids used in the creation of medications and pharmaceuticals, pharmaceutical manufacturing facilities employ DBB ball valves.
