Double Block Bleed Valve

What is Double Block Bleed Valve?

Double Block Bleed Valve is a combination of a bleed valve with two block valves. This is a design structure that can allow for two way flow when necessary and to effectively control the liquid flow inside the system. There are different types of valves such as the Double Block Bleed Needle Valve which uses a needle for the block valves. The operation is by rotating the handle attached to the stem which is connected through a threaded bore to the needle. There can be a plug, needle, gate or knife at the end of the stem inside the body of the valve. The Double Block And Bleed Plug Valve uses a plug to sit on the seating and to close and open the valve gate.

The plug could be rubber or metallic depending on the material flowing inside the valve. The Double Block And Bleed Gate Valve is another type which uses gates to control the flow through the block valves. The gate is attached to the stem and the stem descends or ascends into and out of the body. The gate can be made up of steel or other high alloy materials. The Double Block And Bleed Knife Gate Valve uses a knife that is connected to the stem. The knife is essentially a gate that has a sharp edge. The knife gates are used to cut through high viscous liquids. The double block bleed valves are efficient and have less or no water hammer effects.
