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

(1) The energy used is different Pneumatic components and devices can adopt the method of centralized air supply in the air compressor station, and adjust the working pressure of their respective pressure reducing valves according to different use requirements and control points. Hydraulic valves are equipped with oil return lines to facilitate the collection of used hydraulic oil in the oil tank. The pneumatic cont

Pneumatic valve and electric valve are two kinds of valves that are widely used in the market. What is the difference between pneumatic valve and electric valve? Appearance difference: they are all composed of actuator and valve body, electric valve limit switch is in the electrical equipment, pneumatic valve limit switch, air source filter, solenoid valve. Time difference: Pneumatic valves should switch quickly, D

Pneumatic control valve can be roughly divided into: pneumatic ball valve, pneumatic butterfly valve, pneumatic gate valve, pneumatic globe valve and so on. The first two are switch modes of angular stroke, and the latter two are switch modes of straight stroke. Common angular stroke pneumatic devices can be divided into two categories: rack-type pneumatic actuators and fork-type pneumatic actuators. Both use air pr
