Q41PPL High Temperature Ball Valve Application features
Q41PPL high temperature ball valve adopts new sealing material as the valve seat, which has the advantages of stable performance, reliable sealing, low friction, light switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance, long service life, ETC. It is widely used in petroleum, 冶金, chemical industry, rubber, 造纸, pharmaceutical and other industries. 适用介质: 水, 蒸汽, thermal oil, gas, ETC。, operating temperature: ≤550℃. It is mainly used to cut off or connect the medium, and can also be used to regulate and control fluids. Compared with other valve types, ball valves have advantages
1. The fluid resistance is small. The ball valve has the smallest fluid resistance among all valves. Even the reduced diameter ball valve has a very small fluid resistance.
2. The switch is quick and convenient. As long as the valve stem rotates 90°, the ball valve completes the fully open or fully closed action, making it easy to open and close quickly.
3. The opening and closing of the ball valve only rotates 90°, so it is easy to realize automatic control and long-distance control. The ball valve can be equipped with a pneumatic device, an electric device, a hydraulic device, a gas-hydraulic linkage device or an electro-hydraulic linkage device.
4. The ball valve channel is flat and smooth, and it is not easy to deposit media, so the ball valve can be passed through the pipeline.
