Square stem soft-seated butterfly valve refers to a butterfly valve in which both sides of the sealing pair of the butterfly valve are made of metal materials or hard materials, and the other side is made of elastic non-metallic materials. This kind of butterfly valve has better sealing performance, but limited by the material, it is not easy to withstand high temperature, easy to wear and has poor mechanical properties.

Since there are soft-seal butterfly valves, there must also be hard-seal butterfly valves. Hard-sealed butterfly valve means that both sides of the butterfly valve sealing pair are made of metal materials or other hard materials. Compared with Square stem soft-seated butterfly valve, the hard-sealed butterfly valve has poor sealing performance, but the hard-sealed butterfly valve has better mechanical properties. , high temperature resistance and long service life. In practical application, hard seal butterfly valves and soft seal butterfly valves are not used alone, but are often used in combination to make up for each other's deficiencies.
Square stem soft-seated butterfly valve is different from the previous soft-seated butterfly valve with poor mechanical properties. It uses the advanced triple eccentric structure principle. The valve seat and valve body are integrated components. In addition, the sealing surface of the valve seat is surfacing and resistant to high temperature. and corrosion-resistant alloy materials. This design makes the Square stem soft-seated butterfly valve high temperature resistant, easy to operate, and compensates for the seal with the increase of the torque of the transmission mechanism when it is closed, which greatly enhances the sealing performance of the butterfly valve and prolongs the service life.
