When does Nanchang electric flange butterfly valve automatically close? What is a pneumatic high-pressure ball valve? It is very simple. From its structure, it is composed of a sphere and two sealing seats. If the sphere is closed, the medium force at the upstream end will act on the sphere, which will make the sphere compress the seal seat at the downstream end. At this time, it is easy to generate a working specific pressure. When the working specific pressure is greater than the required sealing specific pressure, it can form a good seal. Having said so much, I just want to let you know some properties of pneumatic high-pressure ball valve, so that we can select a better model.
、 The electric ball valve device is convenient, and it can be used for complete active control. No manual control is required. For elastic sealing valve, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate. Metal seal valves generally have more lifespans than flexible seal valves, but it is difficult to achieve good sealing. Metal seals can get used to higher working temperature, and elastic seals have the defect of temperature constraint.
