Tianjin Milestone Valve Company was one of China Knife Gate Valve, Globe Valve and Flanged Butterfly Valve manufacturers and suppliers, was established in 2019 merged a valve factory in Tianjin. After absorbing the strength of previous factory, now we become a professional manufacturing enterprise in the industry, with patent products: large diameter flange butterfly valve, double clip butterfly valve, fully lined rubber butterfly valve and groove butterfly valve.
The motorized butterfly valve is composed of electric actuator and butterfly valve. According to different working modes and working conditions, it can be divided into switch control type and intelligent adjustment type. The sealing form is divided into soft seal and hard seal. Through the electric actuator, the rotating valve rod drives the disc plate to open and close in the range of 0°-90°.
Read MoreSend InquiryCast Iron globe valve is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so Cast Iron The diameter of the valve stem of the globe valve should be large, otherwise the valve stem will bend up failure.

The lining material uses FEP (F46) and PCTFE (F3) and other fluoroplastics, which can be applied to various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, and Water and various organic acids, strong acids.

In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis of the valve stem, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is in a fully open state. Rubber lined butterfly valve should generally be installed horizontally in the pipeline.
