(5) Because PTFE and other materials have good self-lubrication, small friction loss with the ball, so the service life of the ball valve is long. Technical Parameters Pneumatic Cut off Ball Valve Size DN(mm) 15 20 25 32 40 50 65 80 100 125 150 200 250 300 KV 21 ...
Reduced Friction: Ball valves have low friction compared to other types of valves, such as globe valves. This can result in less wear and energy savings in some applications. Fire-Safe Design: Certain ball valve designs incorporate fire-safe features, making them suitable for use in fire protec...
breaking that is always seen in the Ball valves and the shortages that is experienced correspondingly, it has been aimed to manufacture a ball valve which is long-lasting and operates properly by means of opening-closing without contacting the Seal (3) with the Ball (2) when the valve is ...

3. As an integral ball valve, the PVC ball valve has less leakage points and is easy to use. 4. PVC material has good self-lubricating property, and the friction loss with the ball is small, so the service life of the ball valve is long. Packaging & Shipping Related ...
5. There is no bracket connection between the ball valve and the electric actuator. The integrated compact structure reduces the space.6. The sealing material of PTFE has good self-lubrication and small friction loss with the ball. So that the work life of the ball valve will be longer...
1. Anti-static performance: a spring is arranged between the ball, the valve stem and the valve body, and the static electricity generated by the switching process can be derived.2. Since the material such as polytetrafluoroethylene has good self-lubricating property and the friction loss with...
5. Since the material such as polytetrafluoroethylene has good self-lubricating property and the friction loss with the spherical body is small, the service life of the ball valve is long.6. The bottom mounted valve stem and the stem of the valve stem prevent the valve stem from b...
5. Well self-lubricating for PTFE, little friction loss with valve body, so long life for ball valve. 6. The valve stem and the stem head installed from bottom of sleeve, prevent valve stem from blowing out, for example, fire will destroy the sealing of the valve stem, and form metalic...
A butterfly valve should have a range of possible shaft diameters for each nominal valve size in order to handle the variation in torque due to various operating pressure conditions and packing box friction. Shafts should not be made of material prone to creep, such as some austenitic stainless...
