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

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

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

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
Read more >>The working principle of the electric globe valve is to make the valve unblocked or blocked by rotating the valve. The gate valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in a closed state, not easy to be eroded by media, and are widely used in various industries.
