Manual slide valve, also known as manual spiral gate valve, is usually used in conjunction with unloaders. The diameter of the manual spiral gate valve matches the feeding port of the unloader, and there are two types: square and circular. The advantage of this valve is that the valve body diameter has no grooves, the medium will not get stuck or blocked, and it has full diameter flow characteristics, suitable for use in pipelines with powder particle media. The sealing structure of the plug-in valve can be divided into soft sealing and hard sealing structures. The manual plug-in valve has good processability, compact structure and other characteristics. The sealing valve seat is designed with a movable structure, which has anti wear and automatic compensation functions, resulting in a longer service life. During the closing and opening process of the plug-in valve, the valve seat and gate always move closely together, which stabilizes the opening and closing force of the valve and has the characteristics of cutting off the medium. Configuring a handwheel allows for direct operation of the handwheel to open and close valves.

The manual plug valve is the main equipment for controlling the flow of powder, crystalline particles, and small particles. Electric plug-in valves are widely used in industries such as metallurgy, mining, building materials, grain, and chemical engineering. This gate is equipped with electric, pneumatic, and electro-hydraulic push rods as driving devices, making it an ideal equipment for controlling flow rate and cutting off quickly. The plug-in valve has a compact structure, wear resistance, low leakage, and is characterized by easy operation, flexible action, and labor-saving. It can work normally in environments with high temperature, high dust, and strong magnetism.

Pneumatic plug valves, electric plug valves, and manual plug valves are mostly used in conjunction with unloaders and are divided into two types: square mouth and round mouth. The type of pneumatic plug valve port should be selected according to the shape of the unloader. The plug-in valve produced by Tianzhe Machinery is durable, with low flow resistance, small size, light weight, easy maintenance, and wide use. The sealing structure of the plug-in valve can be divided into soft sealing and hard sealing structures. The manual plug-in valve has good processability, compact structure and other characteristics. The sealing valve seat is designed with a movable structure, which has anti wear and automatic compensation functions, resulting in a longer service life.
