Product Description

Product Description
This valve is suitable for electric power, petroleum, chemical industry, metallurgy, gold ore powder, coal mine, mineral sand, chemical sewage treatment, sedimentation tank, slaughterhouse wastewater, pneumatic conveying pipeline, beer brewing and other mixtures and other industrial material conveying system pipelines As an opening and closing device for feeding, discharging and exhaust.

Structural features:
1. The valve sealing pair made of high-tech new ceramic structural materials or super-hard surface alloy materials has excellent wear resistance, corrosion resistance, erosion resistance, high temperature resistance, antimagnetic and sealing properties, which greatly extend the service life of the valve.
2. The structure is advanced and reasonable. The floating connection between the double gates is used to form a reliable one-way seal under the action of the medium pressure. Due to the unique structural design of the valve stem, the gate automatically rotates during the valve opening and closing process to realize the gate and The uniform wear between the sealing surfaces of the valve seat produces a self-consistent abrasive effect, and the sealing arrangement is tighter. Therefore, the service life and superior sealing performance are greatly improved.
3. Design the purge port according to different working conditions to automatically eliminate dust accumulation and jamming in the valve cavity. The electromagnetic valve
4. The valve has compact structure, small volume, small opening and closing torque, reliable sealing, and convenient installation and maintenance.
5. Various transmission modes such as manual, pneumatic, electric, hydraulic, bevel gear, sprocket, etc. can be used.
