Analyze cast steel gate valves

The opening and closing parts of cast steel gate valves are gate plates, which can only be fully opened and fully closed, and cannot be regulated and throttled. The gate has two sealing surfaces, and the most common mode of gate valves is two sealing surfaces forming a wedge. Wedge gate valve gate plate can be made into a whole, called rigid gate plate; The electric butterfly valve can also be made into a slightly deformed gate plate, called an elastic gate, to improve its technology and compensate for the deviation of the sealing surface Angle during processing.

1. Asbestos graphite or flexible graphite is adopted for reliable sealing and flexible operation.

2. Widely used in pipelines of various systems of petroleum, chemical, hydraulic and thermal power stations.

3. Compact structure, reasonable design, good rigidity of valve, smooth passage and low flow resistance coefficient.

4. The sealing surface is stainless steel or hard alloy, with long service life.

5. Various fitting flange standards and flange sealing cover can be adopted to meet various engineering requirements and user requirements.
