The 316 Stainless Steel Lugged Knife Gate Valve is a heavy-duty isolation valve designed for industrial, slurry, wastewater, and process applications where reliable shut-off is required. Manufactured with an ASTM A351 CF8M stainless steel body and SS316 + Cr gate/disc, this valve provides excellent corrosion resistance and durable performance in demanding services.
Knife gate valves are commonly used for on/off isolation in applications involving liquids, slurries, and media containing suspended solids. The knife gate design allows the gate to move through the flow path, making it suitable for services where standard gate valves may not be ideal.
This valve features a fully lugged end connection and is suitable for BS Table D, Table E, or ANSI Class 150 flange patterns. It is designed and manufactured to MSS SP-81, with face-to-face dimensions to MSS SP-81-2001 and pressure/temperature rating to ISO 7005-1, 10 bar.
The valve is supplied with manual handwheel operation, with actuation available on request.
This valve is designed for on/off isolation in applications involving water, wastewater, slurry, suspended solids, and general industrial process media. The knife gate design is well suited to services where a standard gate valve may not be suitable.
Yes, this valve is commonly used in slurry and suspended solids applications. The knife gate design allows the gate to cut through or pass through heavier media, making it suitable for mining, wastewater, pulp and paper, and similar industrial services.
The valve body is manufactured from ASTM A351 CF8M stainless steel, which is a 316 stainless steel equivalent casting material. This provides good corrosion resistance for suitable industrial and process applications.
This valve is available with EPDM, metal, or PTFE seats. The best seat option will depend on the media, temperature, pressure, and required sealing performance.
The valve is designed to suit BS Table D, BS Table E, or ANSI Class 150 flange patterns. This makes it suitable for a wide range of common flanged pipework systems.
Yes. The standard valve is supplied with manual handwheel operation, but pneumatic, electric, or other actuation options may be available on request depending on the application and size.
The standard size range is 50NB to 600NB. Larger sizes may be available on request.
