IP2DM
Principle of operation With system pressure on, the regulator poppet valve assembly is in the closed position when the adjusting knob is turned fully counter clockwise (no spring load). By turning the adjusting knob clockwise, the diaphragm / piston moves downward allowing filtered air to flow in through the orifice created between the poppet assembly and seat. Auto-drain - IP2AM The Monnier internal auto-drain is a pilot operated unit. As the water level in the bowl rises, the float ( 13 ) lifts, allowing line pressure to act on a piston, which opens the main discharge valve. As the liquid level falls, the float closes and line pressure shuts the main valve. Under zero pressure conditions, the automatic drain will be in the open position, allowing any liquid to drain away. Automatic dump valve - IP2DM This is a spring loaded valve which will allow the filter / regulator to automatically drain when the pressure in the bowl drops below 0.06 bar (i.e. when air to the plant is shut off). The units can also be drained manually by pushing the protrouding valve stem sideways or upwards.
