70-65 manual flat valve

The working principle of flat plate valves is more complex compared to ordinary cymbal valves. If we want to classify flat plate gate valves in detail, we can also introduce various types of flat plate gate valves that are distinguished according to different operating modes, such as manual flat plate gate valves

The manual flat valve is easy to understand, which means that the actuator is a manual flat gate valve. This type of flat cymbal valve is mainly used for dust flow control pipelines, such as metallurgy, building materials, mining, etc. It is precisely because they are used in these industries that the guide holes of manual flat gate valves are often very easy to clog, and many users even give the guide holes directly to flat gate valves with filtering functions. But this is not enough to solve the impact of dust on the flat gate valve, so a manual actuator is used to facilitate timely detection of dust blockage when opening and closing the flat gate valve

Unidirectional and bidirectional flat valves are mainly operated by a frame, nut, handwheel, sprocket, and handwheel rotation. The screw with nut and gate performs horizontal reciprocating motion to open and close the valve. In principle, there doesn't seem to be much difference, but the accumulated dust can be manually cleaned, which actually achieves the purpose of cleaning the valve
