Brief Introduction of Flange Ball Valve
The flange ball valve refers to a made of the flange material. The ball valve is a widely used new type of valve. Theball valveis mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to be operated with a 90-degree rotation and a small turning torque to close tightly.

Application of :
function: mainly used to switch, cut off, or connect the medium in the pipeline, can also be used for fluid regulation and control.
Applicable medium: water, solvent, acid, natural gas, oxygen, hydrogen peroxide, methane and ethylene
Flange ball valve applications: chemical, petrochemical, petroleum, paper, mining, power, liquefied gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction, and other fields.
Flanged ball valves are also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane, and ethylene, etc., and are widely used in various industries. The ball valve body can be integral or combined.

Main Features ofFlange Ball Valve:
The main features of the flanged ball valve are its compact structure, reliable sealing, simple structure, and easy maintenance. The sealing surface and the spherical surface are often in a closed state, which is not easy to be eroded by the medium and is easy to operate and maintain. It is suitable for water, solvents, acids, and natural gas. General working medium.
The difference between the Ball Valve and
Gate valve: It is also called a gate valve or gate. There is a gate in the valve body perpendicular to the flow direction of the medium. Adjust the height of the gate to adjust the flow of fluid.generally close more slowly. It is generally used in the main control valve of heating pipes and water supply and drainage pipes. Ball valves have been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets, and other departments, as well as people's daily lives.
The gate valve has the advantages of low resistance, tight closing, and no water hammer phenomenon. It is widely used in various liquid and gas shut-off valves. It also has a certain adjustment function, but when it is partially opened, the shutter is susceptible to wet by the fluid, the fluid will cause the vibration of the shutter when the fluid flows, and the sealing surface is easy to wear.
The disadvantage of the gate valve is that the structure is complicated, the price is relatively expensive, and it is not easy to repair, and the solid matter is easily deposited in the valve seat groove and is not tightly closed.
Therefore, it is not suitable for pipelines containing fibrous or solid substances in the fluid. It is commonly used in air, steam, and oil media pipelines, and also used as a vent valve and a valve for low-silk systems.
Gate valve is one of the commonly used shut-off valves, mainly used to connect or cut off the medium in the pipeline, not suitable for regulating the flow of the medium. Q valve is suitable for pressure, temperature, and caliber range, especially for medium and large caliber pipes.
: A ball with an opening is used as the valve core, and the ball is rotated to control the opening and closing of the valve. Ball valves are used in petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel, and other industries.
The ball valve has a simple structure, the ball valve is lighter in weight than the , the structure is relatively simple, and its overall weight is very light, so it can play a better effect in low-temperature media systems; the sealing surface is easy to process, the sealability is also good, and the operation Convenient, fast switching, short start-up and closing time, it can make the test system get a quick optimization, and there will be no impact during the starting and closing of the valve.
But it can not be used to adjust the flow rate. It is suitable for high-pressure (up to 320 gauge) pipelines. At present, due to the limitation of sealing materials, it can only be used below 200 ℃, and can also be used for suspensions and various media with high viscosity. And its regulating performance is worse than the cut-off valve, especially the pneumatic valve (orelectric valve).
