Lug type knife gate valve

Lug type knife gate valveDesigned with lightweight and compact structure as the core, it adopts a combination of knife shaped gate and protruding ear valve body. The bottom of the gate plate has a sharp blade, and the side is embedded with a guide groove. The sealing is achieved by tightly fitting the bottom protrusion with the valve seat. The valve body is designed without a chamber and supports clamp or flange connections. The driving modes include manual, pneumatic, electric, bevel gear and other forms. Its fully lined structure (such as ceramic, rubber, polytetrafluoroethylene) covers all parts in contact with the medium, forming a hard or soft sealing surface, suitable for high wear and high corrosion conditions.

Lug type knife gate valvePerformance Characteristics

Wear resistant and corrosion-resistant: Ceramic or hard alloy sealing surfaces can resist particle erosion and acid-base corrosion, with a service life far exceeding traditional valves.

Reliable sealing: The gate and valve seat adopt hard or soft sealing structures, with self grinding characteristics that can compensate for wear and achieve zero leakage sealing; Some models are equipped with O-shaped ceramic sealed valve seats that support bi-directional sealing.

Strong anti clogging ability: The knife shaped gate can cut fiber or granular media to prevent scaling and blockage; The non chambered valve body avoids medium accumulation and ensures long-term stable operation.

Compact structure: Ultra short structural length saves materials and reduces the weight of pipeline systems; Small footprint, supports pipeline installation at any angle, reduces vibration.

Easy maintenance: Modular design supports quick replacement of seals or gate plates, without the need to disassemble the entire valve, reducing downtime costs.

Cutting function: The gate blade can scrape off the adhesive on the sealing surface, automatically remove debris, and reduce manual intervention.

Application field

Mining and Metallurgy: Processing high wear media such as coal, slurry, and filter residue slurry to resist particle erosion and chemical corrosion.

Electric power industry: used for conveying ash slurry and power plant ash removal systems, capable of withstanding high-temperature particle wear and erosion.

Chemical and petrochemical industries: Control acidic and alkaline solutions, corrosive gases, and other media to prevent leaks caused by chemical corrosion.

Environmental engineering: Treatment of wastewater, mud, pollutants, and clarified water with suspended solids in purification devices to ensure stable system operation.

Paper and Textile: Convey any concentration of pulp, material water mixture, cut fiber media, and avoid clogging.

Municipal sewage treatment: Treating complex media such as sewage and sludge to reduce maintenance frequency and costs.

Food and pharmaceuticals: used for washing and rinsing equipment, grain conveying equipment, malt extract, etc., in compliance with hygiene standards.
