What is Parallel Slide Gate Valve?
Pneumatic ceramic double gate valve is a device used to control the flow of materials. It is usually used in the conveying system of powder and granular materials. Its main feature is that the valve body and valve core are made of wear-resistant and corrosion-resistant ceramic materials to ensure long-term stable operation in harsh working environments. This kind of valve is widely used in chemical industry, metallurgy, building materials and other fields, and can effectively improve the reliability and durability of production systems.
Fundamental of Parallel Slide Gate Valve:
The basic principle of pneumatic ceramic double gate valve is to regulate the flow of materials by controlling the opening and closing of the valve core. The valve core is usually made of wear-resistant ceramic material. It moves in the valve body and changes the opening of the channel, thereby regulating the flow and velocity of the material. When the valve core is closed, the sealing performance of the valve body prevents materials from passing through, but when the valve core is open, materials can pass through the valve smoothly. This design can effectively control the flow of materials, prevent leakage of materials and dust, and ensure stable operation of the system.
Structural features:
The structural features of pneumatic ceramic double gate valve mainly include the following aspects:
1. Material selection: *The valve body and valve core are made of wear-resistant and corrosion-resistant ceramic materials to ensure the long life and stability of the valve in harsh environments.
2. Sealing performance: The valve design focuses on sealing performance to prevent material leakage in the closed state and ensure the operational safety and environmental protection of the system.
3. Anti-clogging design: Some ceramic discharge valves also adopt special anti-clogging designs to prevent materials from accumulating inside the valve, thus improving the reliability of the valve.
4. Circulation channel: The structural design ensures that the material is not blocked during the circulation process and ensures the smooth operation of the fluid.
5. Driving device: Valves are usually equipped with pneumatic driving devices to facilitate automatic control and improve the intelligence level of the production system.
These structural features make pneumatic ceramic double gate valves suitable for various industrial scenarios, especially environments that require high wear resistance and corrosion resistance.

Features of Parallel Slide Gate Valve :
This valve refers to Armstrong valve technology and is fully sealed in any direction after closing. The valve body of our company's new pneumatic ceramic double gate valve is cast in one piece, which has better sealing performance and longer service life, effectively reducing the need for maintenance. The packing uses hard seals.
working principle:
The working principle of the pneumatic ceramic double gate valve involves the movement control of the valve core to regulate the flow of materials. Here's how it basically works:
1. Initial state: In the closed state, the valve core is located in the valve body, blocking the flow channel of the material to ensure that the system is sealed.
2. Opening process: When it is necessary to start the flow of materials, the movement of the valve core is controlled by electric, pneumatic or manual devices. The valve core gradually moves away from the valve body, opening the flow channel.
3. Flow control: The position adjustment of the valve core determines the opening of the circulation channel, thereby controlling the flow and velocity of the material. This allows the operator to adjust the output of material precisely as needed.
4. Closing process: When the material flow needs to be stopped, the valve core is moved back to the valve body through the control device again to close the circulation channel to ensure that the system stops flowing and is sealed.
The key is to use wear-resistant and corrosion-resistant ceramic materials between the valve core and valve body to ensure the valve maintains durability over long-term use. This working principle makes the ceramic discharge valve an important control device in the conveying system for handling granular materials.
