Spring-loaded Regulators

Reval 182 Pilot-Controlled Pressure Regulator

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 Direct Acting Pressure Regulator

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...

Aperval Pilot-Controlled Pressure Regulator

The Aperval is pilot-controlled pressure regulator for medium and high pressure applications. The Aperval is normally a fail to open regulator and specifically will open under the following conditions: breakage of main diaphragm lack of sensing line connection This...
