Pneumatic actuation enables rapid response to control signals, facilitating remote, high-frequency automated operation. This product is widely used in automated production lines across mining beneficiation, metallurgical slag removal, papermaking and pulping, wastewater treatment, chemical processing, and building materials industries. It is particularly suitable for controlling solid-liquid or solid-gas two-phase flow media such as mineral slurry, tailings, coal powder, pulp, sewage, dry ash, and granular materials. It serves as critical equipment for achieving process automation, enhancing production efficiency, and ensuring reliable operation under harsh conditions.PZ643W Pneumatic Wafer Type Knife Gate Valve Product Drawing

OverviewPZL73H Sprocket Operated Lug Type Knife Gate Valve is a specialized knife gate valve that combines chain wheel drive and lug clamp connection. Its core component is a sharp blade shaped gate, which can effectively cut and scrape off the slurry, fibers, and solid particles inside the pipeline. The protruding ear design makes installation and disassembly extremely convenient, especially suitable for pipeline systems that require frequent maintenance or limited space. The sprocket transmission mechanism provides a significant labor-saving effect, allowing operators to easily control valves located at high or difficult to access positions on the ground. Widely used in industries such as mining, metallurgy, papermaking, sewage treatment, coal, chemical, building materials, etc., especially suitable for the following working conditions: pipeline cutting containing solid particles or fiber media such as slurry, tailings, coal slurry, pulp, sludge, etc; Pipeline systems with limited space or requiring frequent disassembly and maintenance; Large caliber valves that are difficult to manually operate require the use of sprockets for effortless control.PZL73H Sprocket Operated Lug Type Knife Gate Valve Product Drawing

OverviewThe PZ573H Bevel Gear Operated Knife Gate Valve is a shut-off valve utilizing bevel gear transmission, specifically designed for handling slurries, fibrous materials, and solid particulate media. Its core component is a sharp gate plate (blade) that effectively cuts and scrapes fibrous materials and deposits within pipelines using its razor-sharp edge, preventing blockages. The incorporation of a bevel gear mechanism converts the relatively small input force from the operating handle into substantial output torque, enabling effortless and efficient opening/closing of large-diameter valves. This makes it particularly suitable for high-pressure differential applications or scenarios requiring robust shut-off capability. Widely used in papermaking, wastewater treatment, mining, metallurgy, coal, and chemical industries, this product serves as the ideal shut-off equipment for pipelines handling pulp, tailings, coal-water mixtures, sewage, slurry, and other media containing solid particles and fibrous materials. Its robust cutting and anti-clogging capabilities make it a critical piece of equipment for ensuring uninterrupted flow in demanding process segments.

OverviewPZ73X Slab Type Knife Gate Valve is a compact valve designed for cutting or isolating harsh media such as solid particles, fibers, and slurries. Its core component is a sharp knife shaped gate plate, which can cut in and cut off the flowing medium when closed like a "plug plate", effectively preventing blockage. This valve adopts a clamp type connection, with a very short structural length and light weight. Its "X" characteristic represents that its gate or valve seat is usually sealed with elastic materials such as rubber for soft sealing, ensuring the tightness of the seal while achieving strong cutting. This product is widely used in industries such as mining, metallurgy, papermaking, wastewater treatment, coal, chemical, and food. It is an ideal cutting device in pipeline systems for processing media such as slurry, tailings, pulp, wastewater, slag slurry, grains, and dry powders. Its excellent anti clogging and tight sealing characteristics make it a key component to ensure smooth flow in harsh solid-liquid two-phase flow conditions.PZ73X Slab Type Knife Gate Valve Product Diagram

Overview The PZ643TC Pneumatic Ceramic Wear-Resistant Knife Gate Valve is a high-performance automated valve specifically engineered for extreme abrasive service conditions. Driven by a pneumatic actuator, it interrupts or permits media flow by vertically lifting or lowering a knife gate with sharp edges. Its core innovation lies in the use of high-tech structural ceramics (such as alumina or silicon carbide) for critical flow-path components (gate, seat, and valve body lining), with “TC” denoting “Ceramic.” The wafer-type connection ensures an exceptionally compact structure, optimized for handling highly abrasive slurries and powdered media. This product represents the ultimate solution for handling highly abrasive and corrosive media. It finds primary application in extremely demanding processes such as ash removal systems in thermal power plants, pulverized coal and water-coal slurry conveyance in the coal industry, tailings and concentrate pipelines in mining operations, dust collection systems in steel mills, and the handling of high-hardness catalysts and granular materials in chemical plants. It serves as the core equipment ensuring long-term, stable, and low-maintenance operation in such high-wear systems.Product drawing of PZ643TC pneumatic ceramic wear-resistant knife gate valve

The ZZJ pneumatic slurry valve is a lightweight shut-off valve driven by a pneumatic actuator, specifically designed for media containing fibers, solid particles, or viscous slurries in mining, papermaking, coal washing, municipal sewage, and chemical production. Utilizing a knife-edge principle, the core component—the gate plate—performs a vertical reciprocating motion under the actuator's thrust. Through the sharp blade at the bottom of the plate, the valve effectively shears through impurities at the moment of closing and presses against the seat to achieve a tight seal. With its short face-to-face dimension, low resistance coefficient, excellent anti-clogging capabilities, and ease of automation, the ZZJ series is a critical execution device for handling harsh media in modern industrial fluid systems.Product Image of ZZJ Pneumatic Slurry Valve

PZ673 Pneumatic Wafer Knife Gate Valve is an industrial automation execution unit combining a pneumatic actuator with an ultra-thin knife gate valve body. Utilizing compressed air as the power source, the pneumatic cylinder drives the piston to move the gate plate in a linear reciprocating motion, thereby opening or closing the pipeline. The core design features a gate plate with a sharp knife-edge at the bottom, which effectively shears through fibers, paper pulp, wood pulp, and impurities at the moment of closing to prevent jamming. The letters H, X, and F represent metal hard seal, rubber soft seal, and fluoroplastic seal, respectively, to meet various temperature, pressure, and corrosive conditions. Known for its short face-to-face dimension, light weight, and low flow resistance, this valve is widely used in paper making, mining, coal washing, chemicals, and sewage treatment systems.Product Image of PZ673 Pneumatic Wafer Knife Gate Valve
