Manual carbon steel knife gate valve

PZ73X/F/H/Y cast steel knife gate valve, also known as cast steel knife gate valve or cast steel knife gate valve, has the advantages of compact structure, reasonable design, lightweight and material saving, reliable sealing, lightweight and flexible operation, small volume, smooth channel, low flow resistance, light weight, easy installation and disassembly. The gate plate of the knife gate valve has a shearing function, which can scrape off the adhesive on the sealing surface, automatically remove debris, and the stainless steel gate plate can prevent sealing leakage caused by corrosion. Suitable for professional pipeline systems such as coal preparation, ash discharge, slag discharge, urban sewage treatment, food, sanitation, medicine, etc. in mining power plants.

oneManual cast steel knife gate valve product introduction:

PZ73X/F/H/Y cast steel knife gate valve, also known as cast steel knife gate valve or cast steel knife gate valve, has the advantages of compact structure, reasonable design, lightweight and material saving, reliable sealing, easy and flexible operation, small volume, smooth channel, low flow resistance, light weight, easy installation and disassembly. It can work normally under working pressure of 0.6MPa-1.6MPa and operating temperature of -29-550 ℃. The blade gate valve has a shearing function on its gate plate, which can scrape off the adhesive on the sealing surface and automatically remove debris. The stainless steel gate plate can prevent sealing leakage caused by corrosion. Suitable for professional pipeline systems such as coal preparation, ash discharge, slag discharge, urban sewage treatment, food, sanitation, medicine, etc. in mining power plants.
