Pneumatic control valves are devices that use compressed air as a power source, with a cylinder acting as the actuator. They are controlled by accessories such as electrical valve positioners, converters, solenoid valves, and retaining valves to perform switching or proportional adjustments. These valves receive control signals from industrial automation systems, allowing them to regulate various process parameters like flow, pressure, and temperature in pipelines. The key features of pneumatic control valves include simple operation, fast response time, and intrinsic safety. Since they don't require additional explosion-proof measures, they are widely used in industries such as petroleum, chemical, power, and metallurgy.
When purchasing pneumatic control valves, simply meeting basic specifications, categories, and pressure requirements may not be sufficient in today’s competitive market. Due to product competition, manufacturers have introduced different innovations under the concept of unified design, leading to their own corporate standards and unique product characteristics. Therefore, when buying pneumatic control valves, it is essential to define more detailed technical requirements and reach an agreement with the manufacturer. These details should be included in the purchase contract. Below are four general requirements for pneumatic control valves:
1. The manufacturing standard of the pneumatic control valve should clearly indicate the national standard number. If the product follows an enterprise standard, the relevant enterprise contract must be attached to the procurement agreement.
2. The specifications and types of the pneumatic control valves must meet the requirements outlined in the piping design documents.
3. The working pressure of the pneumatic control valve must be greater than or equal to the pipeline's working pressure. Ideally, the valve's working pressure should exceed the actual pipeline pressure if possible. Both sides of the valve should be able to withstand 1.1 times the rated pressure without leakage, and the valve body should endure twice the rated pressure when fully open.
4. The model number of the pneumatic control valve should follow national standard numbering rules. If it's based on an enterprise standard, the model description must be clearly stated.
