The Features of Slag Gate Valve

Slag gate valve is suitable for hydraulic system in thermal power station and mud discharge system pipeline of hydraulic project where the nominal pressure PN is between 1.6 and 6.4MPa and the operating temperature is between 0 and 100 degrees Celsius. It is used to cut off or connect the mixture of mud and water in pipeline.

The structural features of slag gate valve:

1. Middle flange bolt connection is used. Both ends of the branch pipe are flange connection or butt welding connection.

2. The opening and closing member uses mandatory sealing of semi-sealing pair, with excellent performance.

3. The material of sealing pair is wear-resistant ceramic or alloy, which is highly abrasion resistant, erosion resistant and has a small friction and a reliable sealing.

4. The structure of the outlet flow channel of sanitary valve body is reasonable, which is free from slag and being stuck and has a flexible opening and closing.

5. After regulation and nitriding treatment on the surface, valve stem has good corrosion resistance, abrasion resistance and wear resistance.

6. Rolling bearings are installed in medium- and large-caliber valves, which makes the opening and closing easy.
