New Technology Soft-Sealed Manual Stainless Steel Flange Industrial Knife Gate Valve

Product Description

PZ73FHXY-1016C Stainless Steel  Knife Gate Valve

Cast steel knife gate valves, also known as cast steel knife-type gate valves, feature a compact structure, reasonable design, lightweight and material-saving construction, reliable sealing, easy and flexible operation, small size, smooth flow path, low flow resistance, light weight, and easy installation and disassembly. They can operate normally under working pressures of 0.6MPa-1.6MPa and operating temperatures of -29-550℃. The gate of the knife gate valve has a shearing function, which can scrape off adhering substances on the sealing surface and automatically remove debris. The stainless steel gate prevents sealing leaks caused by corrosion.

Specification

Applications

Knife gate valves are suitable for specialized pipeline systems in mining and power plants for coal preparation, ash and slag removal, urban sewage treatment, food processing, sanitation, and pharmaceutical applications.

Key Features

1. Ultra-short structural length saves materials and significantly reduces the overall weight of the pipeline system.

2. Small footprint effectively supports pipeline strength and reduces the possibility of pipeline vibration.

3. The gate is made of austenitic stainless steel, greatly improving corrosion resistance and effectively preventing leaks caused by gate corrosion.

4. The upper sealing packing uses flexible PTFE, ensuring reliable sealing and easy, flexible operation.

5. The gate functions as a "knife gate," effectively blocking various impurities in the medium.

Advantages

Ultra-thin knife gate valves, with their advantages of small size, low flow resistance, light weight, easy installation, and easy disassembly, have completely solved the problems of high flow resistance, heavy weight, difficult installation, and large footprint of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves, and other similar valves. Since the advent of knife gate valves, a large number of general-purpose shut-off valves and regulating valves have been replaced by them.
