Pneumatic Control Switch 1 (Alumunium)

Pneumatic Control Switch 1 (Alumunium)

The air control switch has a housing made of aluminum alloy, processed and anodized, and assembled into units.  It is installed in the tanker operation box and uses the tanker's own air source to control the pneumatic valves in each compartment. The QKC series adds a new feature of a branch route indicator. When the main air circuit is open (with the main handle pulled, and air pressure between 0.5 MPa and 0.8 MPa), the branch handle  opens, the branch air circuit is activated, and the green indicator block on top extends. When the branch handle is closed, the branch air source is cut off, and the green indicator block retracts.
