Pneumatic plug valveFeatures:
Pneumatic plug valves are the primary control equipment for the flow or conveying quantity of powdered, granular, granulated, and small piece materials, widely used in metallurgy.MiningFlow control or rapid shutdown in industries such as building materials, grain, chemicals, etc. Pneumatic gate valves offer the advantages of simple structure, flexible operation, lightweight, no jamming, and are particularly suitable for various solid materials and substances.50mmThe conveyance and flow regulation of blocky and granular materials, installation is angle-independent, easy to operate, and can be adjusted at any time. Structural features include simple structure, flexible operation, light weight, no jamming, and quick cutting, particularly suitable for all types of non-viscous solids, powders, and materials smaller thanΦ10mmGranule material conveyance and flow regulation, with installation not restricted by angle, easy operation, and the ability to adjust the opening at any time. Primarily used in storage tops, bottoms, and进出口 of industries such as construction materials, metallurgy, mining, power, chemicals, glass, light industry, and grain. It is an ideal equipment for controlling significant flow variations, frequent startups, and quick cutoffs.

Pneumatic Single and Double Acting Plug ValvesAlso known as a manual knife gate valve，Blade-shapedGate valveIt is a valve with a gate and seat that maintains a tight seal at all times. The principle involves a circular opening of the same size as the valve passage on the gate, which, through the opening and closing of the gate, allows for a complete disengagement and alignment with the passage. The advantages of this valve include a valve body passage without grooves, ensuring the medium does not get stuck or blocked, and it features full passage flow characteristics. The sealing structure can be divided into soft and hard sealing configurations. Through-type knife gate valveIt features precise construction, good craftsmanship, and compact structure. The sealing valve seat is designed as a movable structure with anti-wear and automatic compensation functions, thereby extending its lifespan. During the closing and opening process, the valve seat and gate plate remain tightly sealed while moving, ensuring stable operation force and characteristics such as medium cutoff.
