Single Stage Changeover System Special Manifold Block Gas Pressure Regulator Gas Regulator Panel System
Product Description of Pressure Regulator Stainless Steel
It is used in the double-sided high-pressure gas cylinder to reduce the pressure supply.It can be continuously switched on both sides to achieve continuous gas supply and purge function. The maximum input pressure can reach 20.7mpa（3000psi），corrosion resistance，clean shop assembly test，gas analysis such as high purity gas.
Features
Suitable for uninterrupted air supply, automatically switches to the other end when one end is exhausted
Priority supply source can be set with the gas source priority selection handle
The WR11 pressure reducing valve is the prototype valve, and can be used for corrosive and toxic gases.
WV4C diaphragm valve two-way 3-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

Working principle
The WCOS11 series switching device contains two independent pressure reducing valves. The outlet pressure of the left and right sides is adjusted by operating the linkage valve lever, i.e., when the left side increases, the right side When the right side increases, the left side decreases and the right side supplies air.
When the supply side is exhausted, the supply is automatically switched to the other side
By closing the inlet diaphragm valve and opening the pressure relief diaphragm valve, the exhausted side is emptied, and then replaced with a new air supply.
Priority supply source can be selected by turning the switching handle

The application areas of special gases are mainly in the four fields of integrated circuit manufacturing, solar cell, compound semiconductor, liquid crystal display and optical fiber production, among which the main application is in the production of semiconductor integrated circuits. There are more than 110 kinds of special gases used in the semiconductor industry, of which 20-30 kinds are commonly used. 
The boxes of the reducer connector solenoid valve and valve products are customized, and the boxes are usually filled with tape. After wrapping a layer of tape on the outside, the boxes will be fixed with a layer of tensile film to prevent damage. The logistics are normally federal, UPS, etc. If you need to use the designated logistics, you can communicate with the customer service
