The Ceramic Double Disc Gate Valve by LIDON VALVE serves a primary function in handling the feeding and discharge of dry powder in transport pipelines. It utilizes robust toughened ceramic for its shut-off mechanism, ensuring durability and wear resistance. The valve incorporates a pressure self-sealing design and an automatic rotation feature for the valve disc. This innovative construction enhances the wear resistance of the sealing surface during frequent opening and closing cycles with dry powder. As a result, the valve not only meets high sealing performance standards but also ensures an extended operational lifespan.

Characteristics

1. Simple structure and easy maintenance

The structure of the double gate valve is relatively simple, consisting of two parallel gates connected to the pipeline through ordinary threads. Therefore, the double gate valve is not only easy to install, but also relatively easy to maintain.

2. Long service life

The sealing surface of the double gate valve is made of metal materials, such as stainless steel, copper alloy, etc., which have been specially treated to have high hardness and wear resistance. Therefore, the service life of double gate valves is relatively long, up to several years.

3. Good sealing performance

The sealing surface of the double gate valve is made of metal material and has good sealing performance. In addition, the double gate valve also has the characteristics of two-way sealing, that is, it has good sealing performance in both directions. Therefore, double gate valves are widely used in the field of fluid control.

4. Easy to operate

The operation of the double gate valve is relatively simple. You only need to rotate the valve cover to complete the switching operation. In addition, the double gate valve can also be automatically controlled electrically or pneumatically to improve production efficiency.
