The custom diverter flap valve is used to transport powdery materials . And this custom valve controls the direction of material flow.
The flow direction can be changed by adjusting the position of the valve core in the cylinder. Widely used in building materials, metallurgy, mining , light industry, food and other industries.
It is an ideal equipment for changing the flow direction of materials in solid grain and powder material conveying systems. The electric distribution valve is mainly controlled by an electric actuator, which is operated by inputting a 4-20mA electrical signal.
Features
This custom valve adopts high-quality steel plate welded structure, which has small size, light weight and low resistance. It is driven by electric push rod, electro-hydraulic push rod and pneumatic push rod, which can quickly switch the material flow.
Equipment composition
This custom diverting flap valve is mainly composed of valve body, valve shaft, valve plate, crank mechanism, electric actuator, etc.
Working principle
The valve consists of four parts: electric actuator, shell, arc-shaped valve plate and lower inflation device. When working, the electric actuator drives the arc-shaped valve plate to swing at a certain angle through the central axis to adjust the set position.
The lower inflation device fluidizes the material on the breathable layer and transports it out along the discharge direction. This achieves the purpose of controlling material flow and distributing materials.
Operation method
It includes four modes: manual, electric, pneumatic and electric.

Operation precautions
1. Install a regulating valve on the gas path before the gas enters the inflation device at the bottom of the electric distribution valve to control the amount of air intake, and drain the gas tank regularly according to actual operating conditions.
2. Before operation, let low-pressure air (the low-pressure air should be filtered by the dryer) enter the breathable layer before allowing material to be fed; when parking, the material should be stopped first, and then the air source should be turned off; when parking for a long time, the Clean the material on the breathable layer.
3. The air source entering the breathable layer should be a Roots blower.
4. Materials and debris that are agglomerated, agglomerated and have a humidity >1% are not allowed to enter to prevent the arc-shaped valve core from getting stuck.
