Norgen Manifold Relieving Regulator R72M-2AK-RMN
Regulators ideally provide a constant outlet pressure independent of variations in inlet pressure or flow.
Regulators are typically used to:
a) reduce pressure to the level required for downstream equipment
b) limit the force of cylinders
c) minimize pressure variation at the point of use
The range of different regulators and options within each type are wide and varied, but each can broadly be put into
application specific regulators
General purpose regulators are designed to give the maximum flow capacity (for their size) while maintaining, to a reasonable accuracy, the outlet pressure to the set level. They are used to control pressures in compressed air line installations to different parts of machines or to pneumatic tools and motors. General purpose regulators are available in relieving or non-relieving types. Relieving regulators can be adjusted from a high pressure to a low pressure. Even in a dead end situation relieving regulators will allow the excess downstream pressure to be exhausted. This causes a loud hissing sound which is perfectly normal. Non-relieving regulators when similarly adjusted will not allow the downstream pressure to escape. The trapped air will need to be released in some other way, for example by operating a downstream valve. General purpose regulators have a control spring which acts on a diaphragm to regulate the air pressure. The rating of this control spring determines the adjustment range of the regulator. The outlet pressure setting is obtained by turning the knob (or T handle) clockwise to increase pressure, counter clockwise to decrease pressure.
