How to install a vacuum ball valve is more reasonable

How to make the vacuum ball valve more reasonable?

1) Remove the maintenance cover at both ends of the flange end and clean it with the valve open.

2) Before the device, the whole machine test should be carried out according to the regular signal (electricity or gas) (to prevent the use of oscillation due to the impact of the transmission). After passing the test, the device can be put on the line (wiring according to the circuit diagram of the electric actuator).

3) Before the pipeline is connected, the residual impurities in the clean pipeline must be washed and cleaned (these materials may damage the seat and the ball)

4) During the installation of the pneumatic ball valve, please do not use the actuator part of the valve as a lifting hoist to prevent damage to the actuator and accessories.

5) The pneumatic ball valve should be installed in the horizontal direction or straight direction of the pipe.

6), the pneumatic ball valve device points adjacent to the pipeline can not have the phenomenon of low hanging or external force, can use the pipe bracket or the support to eliminate the pipeline violation.

7) After connecting with the pipe, please insert the locking flange connection bolt with regular torque.
