• No soiling may be allowed to collect on or in the filters, reservoirs or windows.
Replace reservoirs if soiling cannot be removed from the drain (drain may be-
come clogged).
Also observe the "Customer information on material resistance in compressed air
preparation" (MNR R412025273)

3 Scope of delivery

• 1x Pressure regulator valve or filter pressure regulator valve (see: Order)
• Optional: Pressure gauge enclosed separately
• 1x Operating instructions

4 Product description

Pressure regulator valves and filter pressure regulator valves are components of
maintenance units. These valves serve to reduce the applied system pressure to a
maximum, regulated working pressure.
Filter pressure regulator valves form a compact unit and are also used for coarse
compressed air filtering.

5 Assembly, commissioning and operation

Danger of injury if assembled under pressure or voltage!
Assembling when under pressure or voltage can
lead to injuries and damage to the product or system components.
1. Make sure the relevant system part is without voltage or pressure prior to
assembly.
2. Protect the system against being restarted.
Sudden pressure increase during commissioning!
The system is exposed to sudden pressure on commissioning if no SSU filling
unit is used! This may result in dangerous erratic cylinder motions.
When commissioning a system without an SSU filling unit, make sure that
u
the cylinders are in their end position. For cylinders not in the end position,
make sure they do not present any danger.
System is operating under pressure!
Incorrect installation could damage the product and cause serious injury.
Before commissioning, check that all connections, ports and maintenance
u
equipment have been correctly installed.
5.1 Mounting fastening elements W01 – W05
See g Fig. 8 to g Fig. 12

5.2 Mounting the pressure gauge

See g Fig. 1 (I)
If a pressure gauge is not mounted, the blanking screw must be
screwed into the pressure regulator valve and sealed.
The blanking screw must be ordered separately.

5.2.1 Pressure gauge with radial seal

1. Firmly screw the pressure gauge by hand into the pressure gauge thread until
the seal is completely screwed into the thread.
2. Tighten the pressure gauge with an open-end wrench (SW 14) by at least a
1/2 turn and align it visually at the same time.

5.2.2 Pressure gauge with axial (metal) seal

If the pressure gauge was ordered separately, the compression ring is
supplied as a separate part.
1. Mount the compression ring on the pressure gauge.
2. Turn the pressure gauge into the pressure gauge thread until the compression
ring is flush against the sealing face.
3. Seal off the connection while aligning the pressure gauge at the same time by
tightening with max. one turn (open-end wrench SW 14). Max. tightening
torque 7 – 8 Nm.

Before commissioning

Let the product acclimatize for several hours before commissioning. Other-
u
wise, water may condense in the housing.
Check that all electrical and pneumatic connection ports are connected or
u
plugged.
Only operate a fully installed product.
5.3 Adjusting the pressure
See g Fig. 2
1. Pull the handwheel (a) up.
2. Turn the handwheel (a) to set the desired pressure.
3. Push down the handwheel (a). This relocks the handwheel.
The safety eyelets need to be retracted fully for any pressure readjust-
ment.
Retracting the safety eyelets
Turn the top rim of the handwheel clockwise until the safety eyelets are fully
u
retracted.

5.4 Locking the handwheel

See g Fig. 3
To prevent any unauthorized change of the pressure setting, the pressure regula-
tor valve handwheel can be locked using a key (AS1) or a padlock (AS2 – AS5).

5.4.1 AS1

To lock handwheel:
Turn key clockwise and then pull it out.
u
To unlock hand wheel:
Turn key counterclockwise and then pull it out.
u
5.4.2 AS2 – AS5
To attach padlock:
1. Push down the handwheel (a).
2. Turn the top rim (b) of the handwheel in counterclockwise direction to lock-
ing position.
This extends the safety eyelets (c).
3. Hang the padlock into one of the safety eyelets (c) and lock it.
5.4.3 AS1 – AS5 (E11)
Version with E11 locking
Supplied without key. Key must be ordered separately.
To lock handwheel:
Turn key clockwise and then pull it out.
u
To unlock handwheel:
Turn key counterclockwise and then pull it out.
u
RGP precision pressure regulator valves and some RGS pressure regu-
lator valves permanently release the internal air consumption to the
atmosphere. A leakage noise is emitted during this process.
