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.

Assembly, commissioning and operation

CAUTION

| 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.

---|---

CAUTION

| 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 the cylinders are in their end position. For cylinders not in the end position, make sure they do not present any danger.

CAUTION

| System is operating under pressure!
Incorrect installation could damage the product and cause serious injury.

• Before commissioning, check that all connections, ports and maintenance equipment have been correctly installed.

Mounting fastening elements W01 – W05

See Fig. 8 to  Fig. 12

Mounting the pressure gauge

See  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.
---|---

Pressure gauge with radial sea

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.

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. Otherwise, water may condense in the housing.
• Check that all electrical and pneumatic connection ports are connected or plugged. Only operate a fully installed product.

Adjusting the pressure

See  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 readjustment.
---|---

Retracting the safety eyelets

• Turn the top rim of the handwheel clockwise until the safety eyelets are fully retracted.

Locking the handwheel

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

AS1

To lock handwheel:

• Turn key clockwise and then pull it out

To unlock hand wheel:

• Turn key counterclockwise and then pull it out.

AS2 – AS5

To attach padlock:

1. Push down the handwheel (a).

2. Turn the top rim (b) of the handwheel in counterclockwise direction to locking position.
   This extends the safety eyelets (c).

3. Hang the padlock into one of the safety eyelets (c) and lock it.

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.

To unlock handwheel:

• Turn key counterclockwise and then pull it out.

| RGP precision pressure regulator valves and some RGS pressure regulator valves permanently release the internal air consumption to the atmosphere. A leakage noise is emitted during this process.
---|---

Semi- and fully automatic condensate drain

CAUTION

| Potential impairment of compressed air system by condensate!
In the case of the semi-automatic condensate drain, condensate is only discharged when the reservoir is not under pressure. If in operation for an extended period, the condensate may exceed the maximum filling level and find its way into the compressed air system. This may result in damage to the compressed air system.

1. Regularly check the filling level in the reservoir.
2. Drain condensate manually once it reaches the maximum filling level.
3. Do not allow the condensate to enter the environment in an uncontrolled manner.

---|---

Semi-automatic condensate drain

See Fig. 4 (I)
The condensate drain opens and closes depending on operating pressure:

• Pressure < 1.5 bar: drain open
• Pressure > 1.5 bar: drain closed

Setting the semi-automatic mode

• Turn the drain screw all the way counterclockwise. You may leave the screw one turn deep in the thread or remove it completely.

Draining condensate manually

See  Fig. 4 (III)
The condensate can also be manually drained (b = maximum filling level).

1. Turn the drain screw (a) all the way clockwise (closed position).
2. Turn the drain screw (a) counterclockwise a few turns until condensate runs out.

Fully automatic condensate drain

See  Fig. 4 (II)
The fully automatic condensate drain is available in versions “open without pressure” and “closed without pressure”. In both versions the valve opens automatically as soon as the floater reaches the highest point and closes again when the it reaches the lowest point.

Version “open without pressure”

The condensate drain opens and closes depending on operating pressure:

• Pressure < 1.5 bar: drain open
• Pressure > 1.5 bar: drain closed

Setting the automatic mode

• Turn the drain screw clockwise as far as it will go.

Version “closed without pressure”

The condensate drain is closed regardless of the operating pressure.

Draining condensate manually

See  Fig. 4 (III)
The condensate can also be manually drained (b = maximum filling level).

• Turn the drain screw (a) counterclockwise as far as it will go.

| If the drain screw is screwed in all the way anti clockwise, the automatic drainage is blocked.
---|---

Disassembly, exchange

CAUTION

| Danger of injury if disassembled under pressure or voltage!
Disassembling when under pressure or voltage can lead to injuries and damage to the product or system parts.

1. Make sure the relevant system part is without voltage or pressure prior to disassembly.
2. Protect the system against being restarted.

---|---

Replacing the pressure gauge

Fig. 1 (II)

1. Unscrew the old pressure gauge from the pressure gauge thread.
2. Mount the new pressure gauge as described in the g 5.2. Mounting the pressure gauge section.

Exchanging the filter

CAUTION

| System is operating under pressure!
Opening the system while under pressure may damage the product and cause personal injury.

• Ensure that the system is not under pressure before you open the reservoir.

---|---

INFO : The filters clog up over time and need to be replaced regularly, at the latest after a year.
This, however, is just a guidance value, since the intervals depend on the compressed air quality and airflow rate.
