Optional extras

Mounting kit - The MR1M, MR2M and MRN1M regulators may be

used with an optional mounting kit consisting of bracket (Type 8 or

Type 4), mounting ring and pressure gauge (see options below).

Mounting kits are supplied separately. Fasteners are not included.

Type 8 mounting bracket and mounting ring (MR2M only)

For panel mounting: An aluminium

mounting ring is to be specified.

For bracket mounting: A Type 8 mounting

bracket and aluminium mounting ring

is to be specified.

Type 4 mounting bracket (MR1M only)

An angle bracket in zinc plated mild steel to enable the regulator to

be mounted behind the panel. The regulator is attached to the bracket

by a screwed nipple.

in both bar and psi. The 40 mm gauge will be supplied unless the

50 mm is specified on the order.

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 flow

to come 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.
