Three three-piece ball valve threaded ball high platform
Three-piece ball valves in the 1950s the advent of a new type of valve, the project pipeline is used to cut off and re-distribution and change the direction of a valve medium, mainly used for cutting, distribution and change the direction of media flow.
Three-piece ball valves compared with other products, with the following characteristics:
1. Ball has reduced diameter and two - port channel, and small fluid resistance, and can reduce local resistance ball.
2. Switch agile fast, easy to use, simply rotate 90 degrees can be completed with the handle opening and closing action.
3. Strict sealing, due to the use of soft seal, making it more secure seal and the sealing surface machining accuracy and surface roughness is not particularly stringent requirements.
4. When opening and closing, the sealing surface of the ball and seat may well spaced and the media, so that the valve sealing surface will not corrode.
5. Safe and reliable, ball valve seat sealing a pair of deputy does not produce abrasion and wear; stem with a built-in, and reduce stem fluid pressure; anti-static, fire-resistant structure ball, more widely.
6. The three ball valve valve body channel smooth and flat, suitable for transporting viscous fluids, slurries and other solid particles.
7. The design is simple, compact dimensions, light weight, compact, reliable, simple operation, easy maintenance.
8. The seal is part of a floating, easy disassembly renewal.
9. diameter size has high vacuum and high pressure can be used normally.
10. Long life, because polytetrafluoroethylene has a good self-lubricating, low friction ball of damage, can increase the life of the valve.
