Ball valve installation：
1. Remove the protective covers on both sides of the flange, and rinse and clean with the valve fully opened.
2. Before installation, the whole machine should be tested according to the specified signal (electricity or gas) (to prevent the vibration caused by transportation from affecting the performance), and then it can be installed online (wiring according to the wiring diagram of the electric actuator).
3. Before preparing to connect with the pipeline, flush and remove the remaining impurities in the pipeline (these substances may damage the valve seat and ball).
4. During installation, please do not use the actuator part of the valve as a lifting point to avoid damage to the actuator and accessories.
5. This type of valve should be installed in the horizontal or vertical direction of the pipeline.
6. The pipeline near the installation point should not be drooping or bear external force. Pipe supports or supports can be used to eliminate pipeline deviation.
7. After connecting with the pipeline, please cross-tighten the flange connecting bolts with the specified torque.
Operation and use of ball valve：
1．Before operation, make sure that the pipeline and valve have been flushed.
2．The operation of the valve drives the valve stem to complete rotation according to the size of the input signal of the actuator: when it rotates 1/4 turn (90°) in the forward direction, the valve is closed. When reverse rotation 1/4 turn (90°), the valve opens.
3．When the direction indicating arrow of the actuator is parallel to the pipeline, the ball valve is in the open state; when the indicating arrow is perpendicular to the pipeline, the ball valve is in the closed state.
