Sensus 122-12 2-1/2" NPT Gas Pressure Regulator

Sensus Model 122-12, 2-1/2" NPT Industrial Combustion Regulator provides large capacity. It has a 12" Diaphragm; 1/4" Inlet and Outlet Taps. Carefully engineered internal sensing produces accurate pressure control without an external control line. And, just in case an 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 speed of response while maintaining stability, which is 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. Springs are color coded. And it is also available as a zero governor or atmospheric regulator, a differential regulator and a relief valve or back pressure regulator.

Other Sensus orifice and spring sizes are available, and sold seperately. These regulators include inlet & outlet taps, 1/4" NPT. Input gas pressures are orifice size dependent, unless a fixed design. Output gas pressures are spring dependent. Ask us how we can help you to change your gas regulator orifice and spring. Sensus is a USG Brand, formerly known as Xylem, Rockwell, Equimeter and BTR.

Standard Model 122 regulators are most widely used on natural gas. However, they perform equally well on LP gas, nitrogen, dry CO2, and air.
