Product Description

Wafer/ Flanged Ends Manula/ Pneumatic Knife Gate Valve (PZ73H)

Product Description

The clamp type knife gate valve is widely used in professional pipeline systems such as coal selection, ash discharge, slag discharge in mining power plants, urban sewage treatment, food, sanitation, medicine, etc.

Product Features

Pneumatic /Manual Knife Gate Valve Features

1. The ultra short structural length saves materials and greatly reduces the overall weight of the pipeline system.
2. It occupies less effective space and can effectively support the strength of the pipeline, reducing the possibility of pipeline vibration.
3. The gate is made of austenitic stainless steel, which greatly improves its corrosion resistance and can effectively prevent sealing leakage caused by gate corrosion.
4. The upper sealing filler adopts flexible PTFE, which is reliable in sealing and easy to operate.
5. The gate has the function of a knife, which can effectively cut off various impurities in the medium.1. The ultra short structural length saves materials and greatly reduces the overall weight of the pipeline system.
