Note: This knife gate valve cannot be used for drinking water.

The stainless steel knife gate valve is available in a pressure range of 1.6 MPa, with a bore size of 80 mm. The wafer knife gate valve has the characteristics of light switch, good sealing, good elastic memory. It is widely used in paper making, petrochemical, mining, drainage, food and other industries.

Features

• The wafer knife gate valve has a knife type beveled cutout, which has the function of cutting off the medium, so that the wafer knife gate valve is not blocked by the medium.
• The wafer knife gate valve features light opening and closing, good sealing, good elastic memory and long service life.
• The 3 inch knife gate valve has a full round passage design and can be set up with multiple flushing ports around the valve body.
• The stainless steel knife gate valve gate can effectively prevent sealing leakage caused by corrosion.

Applications

Knife gate valves are generally used for the circulation of media such as paper pulp, coal ash, chemical materials, sewage, and foodstuffs. RDDLZ stainless steel knife gate valve has the remarkable advantages of light switch, good sealing, good elastic memory, and long service life. It can be widely used in water, sewage, construction, petroleum, chemical, food, medicine, light textile, electric power, ship metallurgy, energy system and another body pipeline as a regulating and intercepting device.

Tips: When is it necessary to replace the sealing parts on the knife gate valve?

Many processors today use knife gate valves in larger sizes to handle the thicker flows of light grease, heavy oil, varnish, slurry, waste water and paper pulp with greater ease. It is important to note that these valves do have low pressure restrictions and are designed to hold the blade in the elastomer seal after it has cut through the substance it is handling. Viscous liquids can easily slide through these soft seals without disturbance, however, when solids or powders pass through the knife gate, large, dry material will eventually build up into the soft seal located at the end of the gate. When this happens, the seals will eventually fail to close tightly. If this happens, the seal will need to be replaced.
