Available in 1" and 1-1/4" sizes.
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.
Note: 122 series regulator must be mounted with the diaphragm in a horizontal position. It cannot be mounted sideways with diaphragm in vertical position.
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 speed of response while maintaining stability...just the thing for those troublesome "snap-acting" loads.
Soft seats plus a precision machined "knife-edge" orifice provide positive tight shutoff. And the orifice is removable.
Regulators are pressure control devices with numerous moving parts subject to wear that is dependent upon particular operating conditions. To assure continuous satisfactory operation, a periodic inspection schedule must be adhered to with the frequency of inspection determined by the severity of service and applicable laws and regulations.
