Pneumatic Ball Valves
Ball valves are divided into pneumatic ball valves, electric ball valves and manual ball valves according to the driving mode. Ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries. This article introduces the application characteristics of ball valves. Let’s find out together.
Ball valve features:
1. The ball valve has small fluid resistance and low flow resistance (actually zero).
2. The opening and closing switch of the ball valve is quick and convenient.
3. The ball valve has good sealing performance.
4. The ball valve has a long service life.
Ball valve.
high reliability of ball valves mainly benefits from:
1. The sealing pair between the ball and the valve seat will not suffer from scratches, rapid wear and other faults, nor will it get stuck during operation (without lubricant). It can be reliably used in corrosive media and low-boiling point liquids.
2. The built-in valve stem structure eliminates the potential accident hazard of the packing gland loosening under the action of fluid pressure and flying out of the valve stem.
3. The ball valve has an anti-static and fire-resistant structure and is suitable for pipelines transporting oil, natural gas and coal gas.
4. The inner channel of the valve body is flat and smooth, which is more suitable for transporting viscous fluids. Mud and solid particles.
5. Since it will not get stuck when working (without lubricant), it can be reliably used in corrosive media and low-boiling point liquids.
6. The spherical closure can automatically position itself above this position and can withstand high pressure differences when closed.
7. Complete two-way sealing can be achieved within a wide pressure and temperature range.
9. When fully open and fully closed, the sealing surface of the ball and valve seat is isolated from the medium, so the medium will not cause erosion of the sealing surface when it passes through the valve at high speed.
10. With compact structure and light weight, it can be considered as a reasonable valve structure for low-temperature medium systems.
