International Compressed Air Regulators Description The IR1M and IRN1M Monnier international compressed airregulators provide accurate pressure control for general purposepneumatic systems. Principal features: - Good flow characteristics. - Good regulation characteristics. - Fast response. - Dead tight shut-off on no-flow. - For line, bracket or panel mounting. - Internal and external high quality black anodised finish. Optional extras For further technical information regarding the following options see page 2: - Tamper-proof cap. - Type 21 mounting bracket. - Mounting ring - Aluminium. - Pressure gauges With system pressure on, the regulator poppet valve assembly isin the closed position when the adjusting knob is turned fullycounter clockwise (no spring load). By turning the adjusting knobclockwise, the diaphragm / piston moves downward allowing flowto come in through the orifice created between the poppetassembly and seat. The control diaphragm / piston offsetting theload spring senses pressure downstream. Increasing downstreampressure causes the poppet assembly to move upward until theload of the spring and diaphragm / piston are balanced. The outletpressure has now been reduced. If a valve is opened downstream,the increased demand for pressure creates a reduced pressureunder the control diaphragm / piston. The poppet assembly movesdownward due to the load of the control spring opening the seatarea and air is allowed to meet the downstream pressure demand.Thus, the area of the opening meters the downstream flow
