1. When a valve is manufactured in batches of a certain specification, an authoritative organization should be entrusted to carry out the following performance tests:
①The opening and closing torque of the valve under working pressure;
② Under the condition of working pressure, the continuous opening and closing times of the valve can be guaranteed to be tightly closed;
③ Detection of the flow resistance coefficient of the valve under the condition of pipeline water delivery.
2. The valve should be tested as follows before leaving the factory:
① When the valve is open, the valve body should be subjected to an internal pressure test twice the working pressure value of the valve;
②When the valve is closed, the two sides are respectively subjected to 1.1 times the working pressure value of the valve, and there is no leakage; but the leakage value of the metal-sealed butterfly valve is not greater than the relevant requirements.
