Stainless steel American standard ball valve installation method

1) Remove the protective covers on both sides of the flange end, and rinse and clean with the American standard ball valve fully opened.

2) Before installation, the whole machine should be tested according to the specified signal (electricity or gas) (to prevent vibration caused by transportation from affecting the performance), and only after passing the line installation (wiring according to the circuit diagram of the electric actuator) for the control type American standard ball valve.

3) Before preparing to connect to the pipeline, the remaining impurities in the pipeline must be rinsed and removed (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 - American standard ball valve should be installed in the horizontal or vertical direction of the pipeline.

6) The pipeline near the installation point must not be sagging or subjected to external force. Pipe supports or supports can be used to eliminate the deviation of the pipeline.

7) After connecting with the pipeline, cross-tighten the flange connecting bolts with the specified torque.

Stainless steel American standard ball valve operation and use method

1) Make sure that the pipeline and valve have been flushed before operation.

2) The operation of the valve is completed by driving the valve stem to rotate according to the size of the input signal of the actuator: when the valve is rotated 1/4 turn (90°) in the forward direction, the valve is turned off. The valve opens when reversed by 1/4 turn (90°).

3) When the direction indicating arrow of the actuator is parallel to the pipeline, the valve is open; when the indicating arrow is perpendicular to the pipeline, the valve is closed.
