Stainless steel ball valve seal formStainless steel ball valve seal form
Q41F stainless steel ball valve is the most widely used stainless steel valve in industrial pipelines. It has the characteristics of reliable and durable sealing performance, simple structure and high cost performance.
1. The fluid resistance is small. The stainless steel ball valve is the one with the least fluid resistance in all valves. Even for the reduced diameter ball valve, the fluid resistance is quite small.
2, the switch is quick and convenient, as long as the valve stem rotates 90°, the ball valve completes the full open or full closing action, it is easy to achieve fast opening and closing, if the speed is faster, pneumatic control can be selected to achieve 1-3 seconds switch control. .
3. Good sealing performance. Stainless steel ball valve seat seals are generally made of elastic materials such as Teflon, which is easy to seal, and the sealing force of stainless steel ball valves increases with the increase of medium pressure. The PTFE used in Zhejiang Qingong Valves is made of domestic high-quality fluoroplastic PTFE. Power plant customers and export customers can also use Japan Daikin, US 3M and other internationally renowned PTFE brands.
4. The valve stem seal is reliable. When the valve stem is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easily damaged, and the sealing force of the valve stem inverted seal increases with the increase of the medium pressure.
5, opening and closing only 90 ° rotation, it is easy to achieve automatic control and remote control, can be equipped with pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage devices or electro-hydraulic linkage devices.
6. The ball inside the stainless steel ball valve is a solid ball. Stainless steel ball valve balls are 304, 304L, 316, 316L, 2205, 2507, 2520, etc. The surface of the ball can also be sprayed with stellite alloy, NI60 alloy, tungsten carbide alloy according to customer requirements and working conditions. The ball valve channel is smooth and smooth, and it is difficult to deposit the medium, and the pipeline can pass the ball.
