Double Block and Bleed Ball Valves

Safety-Oriented Double-Block-and-Bleed Ball Valves

Double-block-and-bleed ball valves (DBB ball valves) allow for a pipe section to be shut down from both sides of the valve. This design feature keeps everyone safe from accidental leaks that can cause harm, making it efficient for the oil and gas industry. Along with strong security features, our valves reduce the need for added valves and save both on space and costs.


To achieve our results, we design the valve thoroughly in our facilities. In maximizing our efficiency, we use a comprehensive range of manufacturing and testing equipment that detects defects early on and ensures faster performance.

DBB Ball Valves Collection

DBB stands for Double Block and Bleed, and it is generally used for regulation of the flow process and the diversion of the flow. Double Block and Bleed valves reduce the time required in installation, require minimal space, and the weight is comparatively lesser on the piping system.


Dombor is one of the best manufacturers of DBB ball valves. We make sure that the DBB Valve produced and used by the companies reduces the leaks of hazardous oil or gas in the atmosphere, which is not good for mankind and the atmosphere.


The structure of a DBB ball is such that it includes two seats on the surface which provides pressure against the seal from both sides of the valve whenever it is in the closed position.

Some of the parts of a ball valve are:

Our DBB ball valves are used for many industries, including the gas and oil industries. It is generally used where the cavity of the valve is bleeding, where maintenance is required, needs isolation, and other situations such as :

When looking for a double block and bleed ball valve, it is very important to consider certain properties of the valve, including the temperature of the ball valve, the pressure of the valve, and the properties of the fluids.

Why do you need a Double Block and Bleed ball Valve?

A double block and bleed ball valve is used to block the flow of any liquid in the system, which helps prevent the liquid being mixed with the other components present there in the system. These are generally used in chemicals, gas, water, petrochemical, etc. The biggest advantage of installing a DBB ball valve is that the no. of leakage is reduced incredibly, which often occurs during the system’s operation.
