Acting German AVENTICS pneumatic valve generally requires the characteristics of Anwochi

German AVENTICS pneumatic valves generally require the characteristics of Anwochi
The Anvochi AVENTICS pneumatic valve is a right-angle rotary structure, which is used with the valve positioner to achieve proportional adjustment. The V-type spool is suitable for various adjustment occasions, with a large rated flow coefficient, large adjustable ratio, and sealed. The effect is good, the adjustment performance is sensitive, the volume is small, and it can be installed in a vertical position. Suitable for controlling gases, vapors, liquids and other media. It is a right-angle rotary structure consisting of a V-shaped valve body, a pneumatic actuator, a positioner and other accessories; it has an inherent flow characteristic of approximately equal ratio; a double-bearing structure, small starting torque, excellent sensitivity and Induction speed; superior shearing capacity The pneumatic piston actuator adopts compressed air as the power source. The movement of the piston drives the crank arm to rotate 90 degrees to achieve automatic opening and closing of the valve.

General requirements for Avative AVENTICS pneumatic valves
1. Pneumatic valve specifications and categories should meet the requirements of the pipeline design documents.
2. The model of the pneumatic valve should indicate the national standard numbering requirements. If it is an enterprise standard, the relevant description of the model number should be indicated.
3. Pneumatic valve working pressure requires ≥ working pressure of the pipeline. Under the premise of not affecting the price, the working pressure of the valve should be greater than the actual working pressure of the pipeline; any side of the pneumatic valve should be able to withstand 1.1 times. The valve pressure value does not leak; when the valve is open, the valve body should be able to withstand the requirements of twice the valve pressure.
4. Pneumatic valve manufacturing standards shall state the national standard number on which the basis is. If it is an enterprise standard, the enterprise contract shall be attached to the procurement contract. Pneumatic valve standard is divided into three categories: national standard, American standard and Japanese standard.
5. The complete description of the pneumatic valve includes its size, material, connection method, and action mode (where the action mode is divided into 1: double action, 2: single action).
Performance requirements
1. When a certain specification of a valve is manufactured in batches, an authoritative organization shall be entrusted to perform the following performance tests:
1 The opening and closing torque of the valve under the working pressure condition;
2 Under the condition of working pressure, it can ensure the tight closing and closing times of the valve;
3 The 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 internal pressure detection twice the valve pressure value;
2 Under the closed condition of the valve, the two sides respectively withstand 1.1 times the valve working pressure value, no leakage; but the metal sealed butterfly valve, the leakage value is not greater than the relevant requirements.
