Working Principle

1. Wcosr11 series switching device includes two independent pressure reducing valves. Adjust the outlet pressure on the left and right sides by operating the linkage lever, that is, when the left increases, the right decreases and the left supplies air; When the right increases, the left decreases, and the right supplies air
2. When one side of the air supply is exhausted, it will automatically switch to the other side of the air supply
3. Close the inlet diaphragm valve, open the pressure relief diaphragm valve, empty the air source on the exhausted side, and then replace with a new air source
4. The priority air supply source can be selected by turning the switch handle

Features

1. It is applicable to the occasion of uninterrupted gas supply. When one end is exhausted, it will automatically switch to the other end
2. With the air supply priority selection handle, you can set the priority air supply source
3. WR11 pressure reducer is used as the prototype valve, which can be used for corrosive and toxic gases
4. Wv4c diaphragm valve two-way three-way valve is adopted, with fewer links
5. Install a 20 micron filter element at the inlet
6. Oxygen environment application options are available
7. The output pressure is within a certain range and has been set at the factory
