Valve specification requirements

1. The model of the valve should indicate the national standard number requirements according to it. If it is an enterprise standard, the relevant description of the model should be indicated.

2. The working pressure of the valve requires the working pressure of the pipeline, and the working pressure that the valve can withstand should be greater than the actual working pressure of the pipeline under the premise of not affecting the first grade.

3. The valve manufacturing standard should indicate the national standard number based on it, and if it is an enterprise standard, the enterprise documents should be attached to the procurement contract.

Performance testing requirements.

1. When the valve is manufactured in batches of a certain specification, the following performance testing should be entrusted to an official organization: The opening and closing torque of the valve under working pressure; Detection of the flow resistance coefficient of the valve under the condition of pipeline water transportation.

2. The valve should be tested as follows before leaving the factory: When the valve is opened, the valve body should be subjected to the internal pressure test of twice the working pressure value of the valve; When the valve is closed, both sides bear 11 times the working pressure value of the valve, and there is no leakage; However, the leakage value of the metal-sealed butterfly valve is not greater than the relevant requirements.
