Is it necessary to install a manual valve on each branch of the instrument air pipeline?
Thread Content
As the title indicates, there is a device that contains 3 pneumatic solenoid valves; when instrument air arrives, it is supplied to these valves through an instrument air pipeline and various branch pipelines. The problem now is that a shut-off valve has only been installed on the instrument air main bus, while none have been installed on the branches. Is it necessary to install one for each branch? The specification for the branch pipeline of the instrument air is G8×1. Is there a suitable manual valve available? I understand that the isolation valve is installed so that individual control is possible during maintenance.
Put up an ad? What are the recommendations for valve selection?
