(1) Remove the protective covers on both sides of the flange end of the pneumatic three-way internal thread ball valve, and flush and clean it when the valve is fully open.
(2) Before installation, the whole machine shall be tested according to the specified signal (electric or pneumatic) (to prevent the vibration caused by transportation from affecting the service performance), and can only be installed online after passing the test (wiring shall be in accordance with the circuit diagram of electric actuator).
(3) Before preparing to connect with the pipe, the residual impurities in the pipe must be flushed and removed (these substances may damage the valve seat and ball).
(4) During the installation of pneumatic three-way internal thread ball valve, please do not use the actuator part of the valve as the lifting point to avoid damage to the actuator and accessories.
(5) Pneumatic three-way internal thread ball valve shall be installed in the horizontal or vertical direction of the pipeline.
(6) The pipeline near the installation point shall not sag or bear external force, and the pipeline support or support can be used to eliminate the deviation of the pipeline.
(7) After the pneumatic three-way internal thread ball valve is connected to the pipeline, please cross lock the flange connecting bolts with the specified torque.
