Because the most important valve seat sealing ring material of the ball valve is polytetrafluoroethylene, it is inert to almost all chemical substances, and has a small friction coefficient, stable performance, not easy to age, wide temperature range and sealing Comprehensive features with excellent......
Read MoreBall valves are a common valve type used to control the flow of fluids (liquids or gases) in pipes. The main feature of the ball valve is that there is a ball (usually spherical) inside the valve body, and the valve is switched on and off by rotating the ball
Read MoreElectric gate valves and imported electric stop valves are the two closest electric valves. They are especially suitable for switching and regulating steam, gas, oil, etc. However, if the two are analyzed in detail, there are still many differences. To understand their differences, there are Help us......
Read MoreIt is not only suitable for medium and low pressure, but also for high pressure. For example, steam cast steel check values, especially bellows check values, are used in projects involving water, oil, steam, gas and other media. Since they are so widely used, this article analyzes its working princ......
Read MoreImported pneumatic ball valve is a widely used type of automatic control valve. It is characterized by fast switching action, good sealing, low resistance and large flow capacity. Convenient remote control, fire and explosion-proof.
Read MoreBecause steam is generally a high-temperature medium, butterfly valves and ball valves are not suitable, and diaphragm valves and knife gate valves are even more inappropriate. The most commonly used on-off valves for steam are gate valves and globe valves.
