1. Product Introduction of Knife Gate Valves
II. Main Types of Knife Gate Valves
By driving method
Manual knife gate valve: Driven by handwheel, it has a simple structure and convenient operation, suitable for on-site manual control.
Pneumatic knife gate valve: Driven by a pneumatic actuator, it enables remote control, has fast opening and closing speed, and is suitable for automated pipelines.
Electric knife gate valve: Equipped with an electric actuator, it can accurately adjust the opening and is compatible with remote automatic control systems
Classified by connection method
Wafer-type knife gate valve: compact in size, easy to install, suitable for pipelines with limited space
Flange gate valve: firm connection, strong sealing performance, suitable for high-pressure and large-diameter pipelines
Classified by sealing material
Wear-resistant rubber-sealed knife gate valve: Elastically sealed with good sealing performance, suitable for slurry and mud working conditions
Metal hard-seal knife gate valve: high temperature and wear resistant, suitable for slurry working conditions with high particle size
III. Core Components
Gate plate: Made of stainless steel or wear-resistant alloy, with a smooth surface, enabling smooth opening and closing without material jamming.
Valve body: Made of cast steel/wear-resistant cast iron, with high structural strength, resistant to erosion and deformation.
Sealing ring / packing: Made of wear-resistant rubber, flexible graphite and other materials, with reliable sealing and leak-proof performance.
Actuator: Manual gearbox, pneumatic actuator, electric actuator, suitable for different control requirements
Fasteners, brackets and other supporting components feature high versatility and easy replacement.
IV. Product Performance Characteristics
Straight-through flow passage without clogging
Groove-free and dead-end-free structure allows smooth passage of ore pulp, mud and granular materials, eliminating gate jamming and material blockage issues
Compact structure with small footprint
Thin valve body design, small installation space, suitable for layout in mine pipeline dense scenarios
Good wear-resistant sealing performance
Special wear-resistant sealing material resists particle erosion, ensuring reliable sealing and long service life.
Light opening and closing with low resistance
The gate plate is thin with small friction, making manual operation effortless. Pneumatic or electric operation is stable with low energy consumption.
Strong adaptability and complete specifications
Full range of nominal diameter specifications, compatible with various actuation and connection methods to meet different pipeline working conditions
Easy maintenance and low cost
Fewer wearing parts, convenient replacement of sealing parts, and lower overall operation and maintenance costs than conventional valves
