Aventics Direction Valve 0821300285 With High Pressure And Durable Sealing Surfaces For Safe Operation

Product Description

The stop valve, also known as the cut-off valve, is one of the most widely used types of valves. It is so popular because during the opening and closing process, the friction between the sealing surfaces is small, it is durable, the opening height is not large, the manufacturing is easy, and maintenance is convenient. It is not only suitable for medium and low pressure but also for high pressure. The closing principle of the stop valve is that it relies on the pressure of the valve lever to make the sealing surface of the valve disc closely adhere to the sealing surface of the valve seat, thereby blocking the flow of the medium. In China's "Three Modernizations" regulations for valves, the flow direction of the stop valve is uniformly required to be from top to bottom, so there is a directionality in installation. The structure length of the stop valve is longer than that of the gate valve, and at the same time, the resistance of the fluid is large. When it is in long-term operation, the sealing reliability is not strong.

The stop valve, as one of the most important types of shut-off valves, plays a significant role in the aerospace field. As an important component of aerospace equipment, the stop valve realizes functions such as medium transportation, cutoff, and regulation. Its sealing performance directly affects the safe and reliable operation of aerospace equipment. Studying the influencing factors and patterns of the sealing characteristics of typical stop valves has guiding significance for the structural design of valve sealing pairs, thereby improving the sealing performance and reliability of the valves.
