(2) before installation, the whole machine shall be tested according to the specified signal (electric or pneumatic) (to prevent the vibration from affecting the performance due to transportation), and the installation can be carried out on line after passing the test (wiring shall be in accordance with the circuit diagram of electric actuator).
(3) before preparing to connect with the pipeline, the residual impurities in the pipeline must be washed and cleaned (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 damaging the actuator and accessories.
(5) the pneumatic three-way internal thread ball valve should be installed in the horizontal or vertical direction of the pipeline.
Or the pipe can not be supported by external support.
(7) after the pneumatic three-way internal thread ball valve is connected with the pipeline, please cross lock the flange connecting bolts with the specified torque.
