A pneumatic valve is a valve driven by compressed air. When purchasing pneumatic valves, it is only necessary to specify the specifications, types, and working pressures to meet the purchasing requirements. flow. The difference between the pneumatic valve and the solenoid valve is the difference in the signal source. The solenoid valve uses electricity to control the pilot gas to push the valve core to change dire

1. Small flow resistance. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small. 2. It is more labor-saving when opening and closing. Compared with the globe valve, because whether it is open or closed, the direction of movement of the gate is perpendicular to the flow direction of the medium. 3. The height is large and the opening and closing ti

1. The solenoid valve has excellent anti-leakage performance, opens and closes quickly, and has low power. It is suitable for use as a cut-off in some chemical pipelines such as corrosion and toxicity; electric valves are mostly used for pipeline flow regulation, and are normally installed in air supply and refrigeration. The air outlet of the pipeline can also be used in liquid pipelines, and is widely used in canne

Electric gate valve is a widely used valve, which is mainly used in the analog regulation of medium flow in liquid, gas and wind systems, and is AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control. The operating principle of the electric gate valve is that the electric gate valve is usually connected by an electric actuator and the valve, an

1.The ball valve has the lowest flow resistance . 2. Because it will not get stuck during work (when there is no lubricant), it can be reliably used in corrosive media and low boiling point liquids. 3. Complete sealing can be achieved in a wide range of pressure and temperature. 4. It can realize rapid opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so as to e

The structure of pneumatic control valve can be decomposed into two parts: valve body (including valve seat and valve hole, etc.) and valve core. According to the relative position of the two, there are two types: normally closed and normally open. The valve can be divided into three types from the structure: globe type, spool type and slide type valve. (1) The structure and characteristics of the globe valve The v
