Block and bleed valve includes block valve and bleed valve. A block valve is also known as stop valve or a globe valve. It is used for cutting off or adjusting or throttle, and it relying on the pressure of the valve bar to seal the surface to prevent the medium flow; and the bleed valve is also named relief valve that adjusting the flow of the medium by controlling the opening of the valve and keep the pressure in a certain range.
The block valve is characterized in its simple structure and it is convenient in manufacture and maintenance, also it takes a very short time in its open and close, what’s more the friction force between the sealing surfaces is small so it is more enduring.
The block valve can be installed in any position of the pipe, and it is mostly used for the fluid with solid particles or the viscosity fluid, such as the alkali organic solvents and some corrosive gases; and the bleed valve is used in fluid environment. The block valve is widely used in the high temperature and high pressure pipeline in thermal power plants, nuclear power plants and petro chemical system.
