The drive of the festo directional cylinder DFM-50-100-P-A-KF is usually a motor, which is quite resistant to voltage surges. Solenoid valves are fast opening and fast closing, generally used in places with small flow and low pressure, where a high switching frequency is required. Electric valves, on the other hand, can control the opening degree, with states of open, closed, and partially open, allowing control of the flow rate of the medium in the pipeline, which solenoid valves cannot achieve. Secondly, the ball of the solenoid valve is elastic. The ball and the valve seat sealing ring are made of metal materials, and the sealing pressure is very high. Relying on the pressure of the medium itself is not enough to achieve sealing, and external force must be applied. This type of valve is suitable for high-temperature and high-pressure media. The elastic ball is obtained by making an elastic groove at the lower end of the inner wall of the ball. When closing the channel, the wedge head of the valve rod makes the ball expand and press against the valve seat to achieve sealing. Before rotating the ball, first loosen the wedge head, and the ball will return to its original shape, creating a very small gap between the ball and the valve seat, which can reduce the friction of the sealing surface and the operating torque. Solenoid valves can be classified by their channel positions into straight-through, three-way, and right-angle types. The latter two types of ball valves are used for distributing media and changing the direction of media flow. The advantages of solenoid valves, according to their structural form, are that the working principle of the solenoid valve relies on rotating the valve to open or close the passage. Pneumatic ball valves are light to operate, small in size, can be made in very large diameters, have reliable sealing, a simple structure, are easy to maintain, and the sealing surface and the ball are often in the closed state, making them less susceptible to erosion by the medium. They are widely used in various industries. Whether the performance of the buffer is stable (especially when used at high temperatures), the matching and manufacturing quality of the spring design play an extremely important role. The springs used within the pressure range of the buffer are divided into several pressure levels (i.e., equipped with several springs). It is obvious that the finer the division, the more springs there are, the more accurate the actual stiffness of each spring is, and the easier it is to ensure the operation of the buffer. However, the material of the springs is usually determined based on the medium and temperature. The material of the buffer, buffers are commonly made of 50CrVA. For corrosive media, 50CrVA with a surface coating of polytetrafluoroethylene is usually used, but this can only be used in conditions where the temperature is less than or equal to 200°C. For conditions above 200°C with corrosion or low temperatures, materials such as 304, 316 stainless steel or Inconel are generally used. For buffers used in applications such as the steam drum of power plant superheated steam, if 50CrVA material is used, an insulator must be added to isolate the spring chamber, or the valve cover can be designed as an open type, or high-temperature spring steels such as 30W4Cr2VA, W1804V can be used. Before installing the festo directional cylinder DFM-50-100-P-A-KF, the pipeline should be cleaned to remove dirt and welding slag. After installation, to ensure that no impurities remain in the valve body, the valve should be cleaned again, that is, when the medium is introduced, all valves should be opened to prevent impurities from getting stuck. After using the hand wheel mechanism, it should be returned to the original neutral position. Secondly, the zero position setting of the pneumatic laboratory actuator is inaccurate and does not reach the fully closed position of the valve. Adjustment method: Although buffers are widely used, other units in the adjustment system probably have not.
