Manual knife gate valve: manual drive, wafer connection, rising rod parallel rigid single gate, valve seat sealing surface is cemented carbide and PTFE, nominal pressure PN10~16, valve body material is carbon steel ( PZ73H-10C/16C), stainless steel (PZ73F-10P/16P PZ73Y-10P/16P), gate valve with slag discharge function.
Structural Principles
It adopts a full-circle channel design, and the upper end of the knife plate is equipped with PTFE, a mud scraper, and a wear-resistant flanged cone made of polygrease or Ni-containing wear-resistant cast iron is installed at the inlet end of the knife gate valve, which can A plurality of flushing ports are arranged around the valve body. The bottom end of the blade is machined into a blade, with high smoothness and good sealing. Widely meet the requirements of papermaking, pulp industry, industrial sewage and municipal sewage treatment, chemical plant, fly ash treatment, bulk material transportation, food and beverage industry and harsh environmental conditions.
