1) Remove the protective cover on both sides of the flange end and rinse and clean the valve in a fully open state.
2) Before installation should be in accordance with the specified signal (electricity or gas) for the whole machine test (to prevent the transport of vibration impact on the use of performance), qualified rear can be installed on the line (wiring according to the electric actuator circuit map).
3) before preparing to connect to the pipe, rinse and remove the remaining impurities in the clean pipe (these substances may damage the seat and the ball).
4) During installation, 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 pipe.
6) The pipe near the installation point must not droop or withstand the phenomenon of external forces, you can use pipe bracket or support to eliminate the deviation of the pipeline. 7) After connecting with the pipe, cross-lock the flange connecting bolts with the specified torque.
