Product introduction
The imported pneumatic cut-off ball valve produced by Breer, the driving method can be pneumatic, electric, the connection can be flanged, the structure can be O-ball valve, the sealing structure can be PTFE, PPL, hard seal, O-ring, pressure range PN1.0MPa-6.4MPa, nominal diameter is DN15-300mm, the material can be selected from WCB, stainless steel, 304,316, chromium molybdenum steel, titanium alloy steel, etc. Because the valve is used in a very wide range, the same valve has different combinations in different situations and working conditions.
Product Details
Imported pneumatic cut-off ball valve (also known as pneumatic O-type ball valve) is composed of ball valve and single (double) acting piston type pneumatic actuator. Pneumatic adjustable cut-off ball valve is widely used in natural gas, oil products, chemical industry, metallurgy, papermaking, electricity, mining, Printing and dyeing, bio-pharmaceuticals, daily chemical, food and beverage, water treatment and air treatment industries, such as fluid cutoff control, used with automatic pneumatic instruments. Pneumatic cut-off ball valve (pneumatic O-ball valve) adopts lip type elastic seal structure design to ensure Reliability of seals For low-pressure, ultra-low-pressure or vacuum operating ball valves, the leaf spring-loaded seat seal structure can ensure long-term reliable sealing of the ball valve. The seat material of the medium and high temperature ball valves can be selected from para-polystyrene or metal. material.
Product features of imported pneumatic cut-off ball valve
1. Small fluid resistance. Ball valve is the smallest fluid resistance among all valves. Even a reduced diameter ball valve has a relatively small fluid resistance.
2. The thrust bearing reduces the friction moment of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
3. The valve seat has a good sealing performance. The sealing ring made of elastic material such as polytetrafluoroethylene has a structure that is easy to seal, and the valve sealing capacity of the ball valve increases as the medium pressure increases.
4. The valve stem has a reliable seal. Because the valve stem only performs imitation rotation and does not perform lifting movement, the packing seal of the valve stem is not easy to break, and the sealing ability increases with the increase of the pressure of the medium.
5. Because the materials such as polytetrafluoroethylene have good self-lubricity, and the friction loss with the ball is small, the service life of the ball valve is long.
6. Bottom-type valve stem and convex step of valve stem prevent the valve stem from spraying out. If the valve stem seal is damaged due to fire, metal contact can be formed between the convex step and the valve body to ensure the valve stem is sealed.
7, anti-static function: a spring is installed between the ball, valve stem, and valve body, which can discharge the static electricity generated during the switching process.
