Replaced Rubber Lined Type Knife Gate Valve
Lixin’s bidirectional heavy-duty slurry valve is designed for slurry applications with a wafer-style face-to-face dimension. The design features twin elastomer seat sleeves and a specially engineered gate to facilitate self-cleaning and prevent media buildup, ensuring reliable bidirectional isolation. 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.
- Face-to-face dimensions follow the short series design, and the lightweight valve body reduces the need for pipe support.
- Continuous flow path design prevents cavities in the open position, minimizing turbulence and load loss.
- Full-bore design provides high flow capacity with low pressure drop.
- Internal flow path design prevents solid accumulation in the seat area.
- Valve seat consists of two rubber ferrules symmetrically positioned on both sides of the valve body.
- Ferrules are made of natural rubber with an internal metal core to maintain shape and prevent deformation.
- Ferrule elasticity ensures permanent contact, preventing solid buildup between valve body components.
- Wear-resistant design ensures reliable shutoff, and ferrules protect the valve body from abrasion.
- Ferrules can be replaced from the outside of the valve body without pipeline removal, simplifying maintenance.
- Standard packing uses a specially designed EPDM V-ring to provide a reliable seal between body and disc, preventing leakage.
- Grease packing strip assists smooth opening and closing operation.
- Packing components can be replaced in an easily accessible position without dismantling the valve from the pipeline.
