pneumatic operated knife gate valve

Knife gate valve（Slide Valve )

There are two types of gate valves: round and square. There are dozens of specifications according to the diameter. They are widely used in metallurgy, carbon, chemical industry, building materials and other industries. The gate valve has the advantages of simple structure, compactness, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

Electric knife gate valve

The opening and closing part of the electric plug-in board is the gate. The movement direction of the gate is consistent with the direction of the fluid.

Perpendicular to each other, the electric knife gate valve can only be fully opened and fully closed, and cannot be used for adjustment and throttling. The gate has two sealing surfaces. The most commonly used gate valve has two sealing surfaces.

The wedge shape and wedge angle vary with the valve parameters.

Manual knife gate valve（Slide Valve )

The manual knife gate valve has a simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

With the advantages of loading and unloading, the manual spiral gate valve can be installed horizontally or vertically, and has the characteristics of anti-wear and automatic compensation function and long service life. During normal use of the manual gate valve, each transmission part should be inspected regularly, lubricated and maintained.

Pneumatic gate valve

The advantages of pneumatic  gate valve are simple structure, flexible operation, light weight and no jamming.

Resistance. It is especially suitable for conveying and adjusting the flow of various solid materials and block and lump materials of about 50 mm. The installation is not restricted by angles, it is easy to operate, and the scale can be adjusted at any time. It is widely used in metallurgy, mining, building materials, food, chemical and other industries to control flow changes or quickly cut off.
