Sensus Model 121 Regulators

The Model 121 is a new dimension in spring regulator capability, offering spring regulator dependability, simplicity and economy. New technology plus contemporary design provides greater capacity, higher inlet pressure, more accurate performance and faster response, with resulting economy — in most cases a smaller regulator will do the job. Use the 121 for commercial and industrial applications: burners, boilers, furnaces, air heaters, kilns, gas engines and benefit from its fast response. Use it also as a large capacity supply regulator on commercial or industrial service lines, or as a small district regulator. It’s excellent for primary control or monitoring — use it for either or both. The 121 is actually a whole new family of regulators – standard regulator, zero governor or atmospheric regulator, differential regulator, back pressure regulator, or relief valve, vacuum regulator and vacuum breaker. Compatible with natural gas, propane, LPG, air nitrogen, etc. Special material available for certain corrosive gases.

Features:

• Allows above-ground or vault installation
• Provides for pilot-operated, pressure-loaded and V-port options
