Pneumatic three-way valve
Thread Content
Let’s consider it this way: under normal conditions, when delivering material from a to b, if there is a power or air supply interruption in the a-c section, it is necessary to maintain pressure in that area. For our pneumatic three-way valve, should we use a single-coil or double-coil version to maintain pressure in the absence of power or air supply? How does the solenoid valve work?
Three-way valves are also divided into types for merging streams and for splitting streams; it would be best if you could provide a schematic diagram so that everyone can help analyze the problem for you!
Are you from the manufacturer or the field engineering side? For on-off valves, position maintenance valves and dual-control solenoid valves can be considered for implementation. Adjustable valves do not require solenoid valves; it is advisable to use a positioner with three-stage protection for this purpose.

I’m very curious too; I hope someone experienced can advise me on how solenoid valves maintain pressure
2-channel 5-way dual control, one air circuit and two power supplies
According to your description. To achieve power loss and air loss under conditions A-C while maintaining the position of the A-C valve, it is not necessary to maintain pressure. A single-coil solenoid valve will suffice.
This shouldn’t be that complicated. If I understand correctly, a single-acting cylinder paired with a solenoid valve should suffice; further details are needed for a precise answer
I need a two-coil three-position five-way solenoid valve. These solenoid valves are not cheap.
