Ball valve installation
1. Remove the protective cover on both sides of the flange, the valve is fully open in the state to wash clean.
2. iInstalled before the required signal (electricity or gas) to carry out the whole test (to prevent the impact of transport vibration caused by the use of performance), qualified rear line can be installed (wiring according to the electric actuator line diagram).
3. Prepare and remove the remaining impurities in the clean piping (which may damage the valve seat and ball) before connecting the pipe to the pipe.
4. During the installation, please do not use the valve body part as a lifting point, to avoid damage to the actuator and accessories.
5. This type of valve should be installed in the horizontal direction or vertical direction of the pipe.
6. Install the pipeline near the falls, or to withstand external force phenomenon, can use pipe support or supports pipeline to eliminate the deviation.
7. After connecting with the pipe, use the specified torque cross locking flange connection bolt.
Operation and use
1. Before the operation must be confirmed that the pipeline and the valve has been washed off.
2. Valve operation according to the actuator input signal size to drive the valve stem rotation: forward rotation 1/4 circle (90 degrees), the valve off. Reverse rotation 1/4 circle (90 degrees), the valve opens.
3. When the implementation of the direction of the arrow and the direction of the pipeline in parallel with the pipeline, the valve is open, indicating the direction of the arrow and the line when the valve is closed, the valve is closed.
