Spring-Loaded Regulators

Reval 182

The Reval 182 is a pilot-controlled pressure regulator for medium and low pressure applications. The Reval 182 is normally a fail to close regulator that will close under the following conditions: breakage of main diaphragm lack of gas feeding to the pilot loop This...

Norval

Norval pressure regulators are direct acting devices for low and medium pressure applications, controlled by a diaphragm and counter spring. These regulators are suitable for use with previously filtered, non-corrosive gases and Bio Gas, depending upon its...
