10-22" WC Red Spring for R400 & R400S

The R & RS series is intended for use with both main burner and pilot load applications. The double diaphragm balanced valve design makes it possible to build a regulator physically small in size yet having good capacity characteristics. They are able to maintain steady outlet pressure control with widely varying inlet pressures. The high quality molded balancing diaphragm eliminates the inlet pressure effect acting on the valve. They are suitable for application in natural, manufactured, mixed gases, liquefied petroleum gases and LP gas-air mixture piping systems.
