Rubber Lined Flanged Type Knife gate valve
Lixin’s bidirectional heavy-duty slurry valve is designed for demanding slurry applications. The design utilizes twin elastomer sleeves and a specially engineered gate that facilitates self-cleaning and prevents media buildup, ensuring reliable bidirectional isolation. The durable ductile iron body is offered in a two-piece bolted flange style. When fully open, the valve provides a full-bore flow path with no resistance to the media. With dedicated workshops and superior mold casting capabilities, Lixin is well equipped to meet your knife gate valve requirements
KEY FEATURES:
- Two-piece valve body.
- Standard Wafer design.
- Integral ultra-thin body structure.
- Knife gate provides strong shearing force.
- Cavity-free flow channel prevents solid accumulation.
- Channel and raised-face flange surface are rubber-lined for excellent wear resistance.
- Bi-directional sealing capability.
- No metal parts in contact with the medium when the valve is fully open.
- Field-replaceable heavy-duty elastomer sleeves.
- Top bracket supports manual, pneumatic, or electric actuators for easy conversion.
- Yoke design consists of two plates that fully enclose the gate, spindle, and stem nut to protect components from slurry splatter and prevent operational issues.
