Knife type gate valve; Manual clamping knife type gate valve
1. Adopting a fully circular channel design, the bottom end of the blade is processed into a cutting edge with high smoothness, ensuring good sealing. 2. The PZ73 knife type gate valve is equipped with polytetrafluoroethylene and a scraper at the upper end of the blade, which can prevent abrasive substances such as dust and gravel from entering the packing box. 3. The wear-resistant folding cone made of polymer grease or Ni containing 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. 4. According 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. 5. The PZ73 manual clamp type knife 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.
