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

1. Pay attention to the flow direction of the medium when installing the valve, and install it strictly in the direction indicated by the flow direction arrow of the valve. 2. The valve can be installed in any position of the pipeline, and the valve of carbon steel or alloy steel can be selected according to the medium and the temperature of the medium. 3. Install it as vertically as possible, with the valve stem u

1. Open and close without friction. This function completely solves the problem that the traditional valve will affect the sealing due to the friction between the sealing surfaces. 2. Top-loading structure. The valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost. 3. Single valve seat design. It eliminates the pr
