NorgreN exceloN® Pressure regulators

R72G-2AK-RMN, shown without gage.

R72G Series

l In-Line or Modular Installation l Full Flow Gage Ports l Balanced Valve Design

Minimizes Effect of Variation in the Inlet Pressure on the Outlet Pressure

l Standard Relieving Models

Allow Reduction of Downstream Pressure when the System is Dead-Ended

These products allow inlet pressure to pass directly through the body. The outlet port is at right angles to the inlet. This then allows units to be “Quickclamped” together in a bank meaning numerous regulated pressures can be obtained from a single supply–see illustration. R72M pressure regulators are ideal for control cabinet installations where neat, compact assemblies are required. See website for additional information.
