① The valve adopts pressure self-tightening seal or valve body and valve cover gasket seal structure, which is trustworthy! Safe and reliable to use.

② The valve disc adopts a double gate with a universal top structure, which can automatically adjust the compatibility between the valve disc and the sealing surface of the seat to ensure the sealing of the valve. At the same time, the structure is convenient for maintenance, cost saving, and the valve disc interchangeability is good.

③ The sealing surface of the valve disc and seat is made of cobalt-chromium-tungsten carbide by plasma spray welding. The sealing surface has high hardness, friction resistance, abrasion resistance and long service life.

④ Valve stem made of nitriding steel, surface nitriding treatment, high hardness, abrasion resistance, corrosion resistance, long service life.

⑤ The electric device is equipped with torque control mechanism, field operation mechanism and hand, electric switching mechanism. In addition to local operation, it can also carry out remote operation, PLC control, 4~20mA current input and output intelligent control.

⑥ The manual valve is opened by the manual mechanism or the hand wheel on impact. Reduce valve operating force.

The valve can be installed in any position of the pipeline, and carbon steel or alloy steel valves can be selected according to the temperature of the medium and the medium.

When installing and debugging for the first time, the valve must be opened manually to about half of the position, so as not to cause valve or electrical damage due to the reverse phase sequence of the motor.
