Design and principle of operation

2 Design and principle of oper-

ation

The supply pressure regulator is used to sup-

ply pneumatic measuring and control equip-

ment with a constant air supply. The maxi-

mum 12bar pressure of the compressed air

network in a plant is reduced to an adjust-

able minimum pressure of 0.5 to 6bar.

The compressed air at the inlet (supply) ows

across the lter and leaves the output with a

reduced pressure depending on the set point

adjusted. The plug is balanced to eliminate

the forces created by the upstream pressure

acting on the plug.

Any water contained in the compressed air

is separated and collected as condensate in

the lter receptacle, which must be mounted

suspended downwards. The collected con-

densate in the lter receptacle can be

drained off by briey pushing the drain

plug.

Mounting the supply pressure regulator

3 Mounting the supply pressure

regulator

ÎTo prevent excessive amounts of con-

densed water from collecting, keep the

distance between the compressor and

supply pressure regulator as short as

possible.

The supply pressure regulator can either be

mounted directly in the pipeline of the air

supply or on rails or brackets using the cor-

responding mounting parts (see accessories

in section8).

ÎObserve the ow direction of the supply

air. An arrow on the nameplate indicates

the direction.

Depending on how the regulator is installed

in the pipe, it may be necessary to mount the

pressure gauge at the back of the supply

pressure regulator (see section 4.1).

4 Pneumatic connections

The air connections (supply and output, see

Fig.1 on page6) are designed either

with ISO-228/1 - G½ or ½-14NPT

threads.

The second pressure gauge on the back of

the regulator can be used to additionally

supply pilot valves with a constant supply

pressure. This connection at the back has a

G

thread.

4.1 Pressure gauge

ÎWhen attaching the pressure gauge,

make sure that the gap between the lock

nut and pressure gauge’s square end is

not smaller than 2 to 3mm.

Mountingthepressuregaugeontheback:

ÎRemove the stopper (hexagon socket

head screw G

) and screw it into the

unoccupied pressure gauge connection

at the front to seal it.
