Series 150 Knife Gate Valve
The Series 150 Knife Gate Valve was fabricated with a bi-directional valve in response to customers needing a robust valve for coarse solids and tailing service in mining. These valves have found use in abrasive bottom ash discharge circuits in coal-fired power plants.
The CAD/CAM designed and CNC plasma-cut components are robot welded and pressure tested to ensure a long reliable life. The cast stainless steel double taper blade ensures a positive open and closes every cycle.
The tapered blade mates to a matching Towniprene urethane seat, that has been chemically bonded to the metal body. Also, the series 150 incorporates opposing high-chrome cast inserts to absorb the constant coarse feed 24/7 with operating temperatures at 165F or lower.
Features:
- The heavy-duty fabricated body resists mechanical and pressure-induced damage
- Flange-style body for improved strength
- Custom “face to face” dimension upon request
- Variety of materials to match application
- Towniprene® urethane-lined seat high-chrome inserts
- Heavy-duty blade cuts through media
- Tapered edges and blade body assures easy opening without binding
- Combine stainless steel blade with Towniprene® urethane-lined seat and body for excellent corrosion resistance
- Features standard 150 PSI rating with higher service rating upon request
- 150# drilling standard, custom drilling by request
- Optional mechanical lockout for safety
- Bi-directional flow
- Hand-wheel standard adaptable to existing actuation or new
- 4″ through 24″ full port IDs, others available on request
- The used valve can be fully rebuilt at our factory
- The bonneted design allows simplified sealing of shaft only
