Knife gate valveFeatures:

1Adopting a fully circular channel design, the bottom end of the blade is processed into a cutting edge with high smoothness, ensuring good sealing.

2PTFE and scraper are installed on the upper end of the blade to prevent abrasive substances such as dust and gravel from entering the packing box.

3Polyglue or containingNiThe wear-resistant flanged cone made of wear-resistant cast iron is installed at the inlet end of the knife gate valve, which can prevent particle materials from directly flushing on the seal, thereby improving working conditions and extending service life.

4According to the needs, multiple flushing ports can be set around the valve body, which can be directly flushed with air, steam or water to prevent sediment from gradually accumulating. It is particularly suitable for fluids with difficult input.

5The knife type gate valve has a compact design, occupies small space, is lightweight, easy to install, has complete wear-resistant and anti blocking measures, is easy to maintain, and has a long service life. Widely meet the usage requirements and working conditions of papermaking, pulp industry, industrial and urban sewage treatment, chemical plants, fly ash treatment, bulk material transportation, food and beverage industry under harsh environmental conditions.

5. FivePZL73H/X/FChain wheel clamp typeKnife gate valveNotes:

1.Before installation, it is necessary to check the valve chamber and sealing surface, and no dirt or sand particles are allowed to adhere to them;

2.The bolts at each connection point should be tightened evenly;

3.Check the filling position and ensure that it is tightly pressed to ensure both the sealing of the filling and the flexibility of the gate opening;

4.Before installing the valve, users must verify the valve model, connection size, and pay attention to the flow direction of the medium to ensure consistency with the valve requirements;

5.Users must reserve necessary space for valve actuation when installing valves;

6.The wiring of the driving device must be carried out according to the circuit diagram;

7.Knife type gate valves must be regularly maintained and must not be bumped or squeezed at will to avoid affecting the sealing.
