Valve Specification Requirements

1. The valve model should indicate the national standard number requirements based on it. If it is an enterprise standard, the relevant description of the model should be indicated.
2. The working pressure of the valve must be ≥ the working pressure of the pipeline. Without affecting the price, the working pressure that the valve can withstand should be greater than the actual working pressure of the pipeline.
3. The valve manufacturing standard should indicate the national standard number it is based on. If it is an enterprise standard, the enterprise document should be attached to the procurement contract.
