Seek help regarding the air circuit of the cut-off valve in the diagram
Thread Content
I’ve been troubled lately by the air circuit of the device’s cut-off valve. Seek help regarding the air circuit of the cut-off valve in the diagram. The manufacturer and model are indicated on the second image: rotex-53402-16-4R
It’s difficult to figure things out just by looking at the diagrams; by going to the site and drawing out the actual connections between the various components, and then understanding how each component works and what the technical requirements are, it becomes much easier.
Is this valve a MAGWEN valve?
The air supply pipeline provides instrument air, which passes through a filter and pressure regulator before going to the solenoid valve that controls the pneumatically operated valve of the ROTEX two-position five-way valve； Another route passes by the check valve; 1. Connect to the instrument air storage tank ； 2. Go to the air source of the air control valve ； 3. Connected to the back side of the solenoid valve, for manual testing or use in emergency situations ； The valve should be a pneumatic double-acting on-off valve, and the failure position in case of power loss is determined based on the pneumatically controlled valve ； The failure location is determined by a small pneumatic valve located in front of the solenoid valve, which controls whether the ROTEX pneumatic valve has a supply of control air, thereby identifying its faulty position. It’s best to find the air circuit diagram of the valve, then it will be easier to analyze.
