(23) Industrial combustion regulators combine new technology with modern design to provide greater capacity, higher inlet pressure, more accurate performance, and faster speed of response. In most cases, this will allow the use of a smaller regulator. Both models of regulators have high strength, corrosion resistant, die-cast diaphragm cases and cast iron bodies, assuring a highly functional regulator at a better price. Both models incorporate soft seat valve material plus a precision machined "knife edge" orifice to provide a positive, tight shutoff.
Use the 121 for commercial and industrial applications; burners, boilers, furnaces, air heaters, kilns, gas engines. Its fast response will help.
(6) For an unbeatable combination of capacity, performance and economy, install the Sensus Metering Systems Model 122...the latest in industrial-combustion type gas pressure regulators.
Streamline body passages provide large capacity.
Carefully engineered internal sensing produces accurate pressure control without an external control line. And, just in case a particular application necessitates one, a handy tap on the 122 makes connection into an external control line a simple matter.
Diaphragm cases are high strength, corrosion resistant die-cast aluminum alloy. This makes a better looking regulator at a better price. In addition, on 1" through 2 1/2" sizes a large area double acting damper in the vent assures fast ...
