AFK Stainless Steel Double Side Gas Supply Automatic Switching Heating Device Pressure Reducing Valve
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
- Suitable for uninterrupted air supply, automatically switches to the other end when one end is exhausted
- With priority selection handle, priority supply source can be set using the WR11 pressure reducing valve as a prototype valve, which can be used for corrosive and toxic gases
- WV4C diaphragm valve two-way three-way valve is used as a prototype valve, with fewer links
- 20 micron filter element installed at the inlet
- Oxygen environment application options are available
- Output pressure within a range, factory set
