200bar High Pressure Changeover Switch Gas Regulator

Features

• Suitable for uninterrupted gas supply, with automatic switch to the other end when one end is exhausted, with a priority selection handle for setting the priority gas supply
• The WR11 pressure reducing valve is the prototype valve, and 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

Working Principle

• The WCOS11 series switching device contains two independent pressure reducing valves. By operating the linkage valve lever to adjust the outlet pressure on the left and right sides, 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

Cleaning process
Standard (WK-BA)
Welded joints are cleaned according to our standard cleaning and packaging specifications, to be ordered without adding a suffix

Cleaning for Oxygen (WK-O2)
Product cleaning and packaging specifications for oxygen environments are available, and this meets ASTM G93 Class C cleanliness requirements; to order, add -O2 to the ordering number

Specialty Gases include rare gases, extremely pure gases and gases of the highest mixing accuracy, which are used in very demanding applications by a wide range of industries.

Many Customers have specific requirements that are not always standard mixtures. For these applications, we are able to provide the Quality Control Solution via our range of  NovaCHROM Gas Chromatographs or Gas Analysers depending on the exact requirement.
