Electric butterfly valve is a kind of regulating valve device used in automatic control system. The control principle of the valve is that it can lead and control the closing of the valve according to the signal of the power supply. Electric butterfly valve has many functions. It is a multi-functional valve that integrates check valve, control valve and shut-off valve.…

Metal valves can be said to be the key component structures that are most prone to corrosion and failure in engineering equipment.…

The turnnion mounted ball valve has a floating valve seat. After being pressurized by the medium, the valve seat moves, so that the sealing ring is tightly pressed on the ball to ensure the sealing. Bearings are usually installed on the upper and lower shafts with the ball, and the operating torque is small, which is suitable for high-pressure and large-diameter valves.…
