The valve adopts tight seal or valve pressure, and the bonnet seal gasket structure is reliable, safe and reliable.

The valve adopts the middle double-plate universal top structure, which can automatically adjust the fitting degree of the valve and the sealing surface of the valve seat to ensure the valve is sealed. At the same time, the structure is easy to maintain, saves cost and has better valve interchangeability.

The sealing surface of the valve seat is sprayed with tungsten carbide, and the cobalt chromium alloy is formed by plasma. The sealing surface has high hardness, wear resistance, wear resistance and long service life.

The valve stem is made of nitrided steel and has a surface nitriding treatment. It has high hardness, wear resistance, corrosion resistance and long service life.

The electric unit of the mine explosion-proof electric valve is equipped with a torque control mechanism, a field operating mechanism and a manual and electric switching mechanism. In addition to local operation, it can also be used for remote operation, PLC control, intelligent control of 4~20mA current input and output.

Manual valve opening mechanism or tapping with a manual handwheel. Reduce valve operating force.

Valves can be installed anywhere in the pipeline, while selecting carbon steel or alloy steel valves based on the temperature of the media and media.

When installing and commissioning for the first time, the valve must be manually opened to approximately half of the position to avoid reverse phase reversal of the motor or damage to the electrical valve.
