Valve a specification of batch manufacturing, should be entrusted to the authority of the performance test: 1. Valve under the working pressure of the opening and closing torque; 2. Under the working pressure, continuous opening and closing times of the valve can be ensured to close tightly; 3. Test the flow resistance coefficient of the valve under the condition of pipeline water delivery;

Valve inspection before delivery: 1. When the valve is open, the valve body should bear double internal pressure of the valve working pressure; 2. Under the closed state, both sides of the valve bear 11 times the working pressure of the valve respectively, without leakage; But the metal seal butterfly valve, leakage value should not be greater than the relevant requirements.
