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

working principle When the globe valve is opened and closed, it is of a rising valve stem type, that is to say, when the handwheel is turned, the handwheel will rotate and lift together with the valve stem. The gate valve rotates the handwheel to make the valve stem move up and down, and the position of the handwheel itself remains unchanged. Flow rates vary, gate valves require fully open or fully closed, and globe
