描述

Non-rising stem knife gate valve

For plastic solids and high-viscosity slurries such as paper pulp, a specialty valve known as a knife gate valve is used to cut through the material to stop the flow. A knife gate valve is usually not wedge shaped and has a tapered knife-like edge on its lower surface.

DISTINCTIVE FEATURES 

□ Wafer or Semi-lugged
■ Full Lugged or Flanged
□ Bonnetless  Design
■ MSS SP-81 Complied
□ Cast Steel or Cast Iron
■ Soft Seat or Metal Seat
□ Uni or Bi Directional
■ API 6D & CE Certified

MAIN CHARACTERISTICS

FUTURE VALVE offer a broad line of universal knife gate valves covering resilient seat and metal to metal seat, ends connection in wafer, flanged and fully lugged which are widely used in various industries, including mining, power plant, urban sewage treatment, food and beverage, paper mill, petroleum, etc

DESIGN ADVANTAGES

Wafer or Fully Lugged bonnetless knife gate valves are with advantages of compact structure, reasonable design, material saving, reliable sealing, convenient operation, small volume, full passage flow, small flow resistance, small weight, easy installation and maintenance.
