Optional extras

Airsets

- The MP2M, MPN2M regulators are also available as

airsets consisting of Type 8 bracket, mounting ring and pressure

gauge (see options below).

Type 8 mounting bracket and mounting ring

The filter/regulator can be mounted using a zinc plated mild steel

bracket and aluminium mounting ring (not shown). Both items must

be specified when placing an order.

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. The control diaphragm/piston offsetting the

load spring senses pressure downstream. Increasing downstream

pressure causes the poppet assembly to move upward until the

load of the spring and diaphragm / piston are balanced. The outlet

pressure has now been reduced. If a valve is opened downstream,

the increased demand for pressure creates a reduced pressure

under the control diaphragm / piston. The poppet assembly moves

downward due to the load of the control spring opening the seat

area and air is allowed to meet the downstream pressure demand.

Thus, the area of the opening meters the downstream flow.
