in life support or other systems not covered in the published instructions, please contact Norgren directly.

Due to misuse, wear, or malfunction, components used in pneumatic systems can fail in a variety of ways.

System designers are strongly advised to consider the failure modes of all component parts used in pneumatic systems

and to take adequate safety precautions to prevent personal injury and equipment damage in the event of such a failure.

System designers are required to include safety information for the end user in the

operations manual if fault protection is not adequately provided.

System designers and end users are strongly advised to follow the safety instructions included with the products.

3. Functional Safety

3.1. General Safety Instructions

Note:

The VP23 is not a design with inherent fail-safe characteristics.

Therefore, no safety-related properties can be guaranteed at valve level.

For machine controls (complex mechatronic systems) with the VP23, a risk analysis

according to e.g. EN-ISO12100 is strongly recommended.

Information on the current standards situation can be obtained from the VDMA or the BGIA.

DANGER - Danger due to hazardous movement

Changes to the valve coniguration can lead to unwanted movements or changes to connected consumers under air supply.

Please establish a safe operating condition before changing the valve coniguration. This also applies

in particular to changes via the USB coniguration interface or the IO-Link parameters.

Use suitable stop and vent valves in the supply lines and at the consumer connections for disconnection.

Warning! - Danger from compressed air

After switching off the pressure supply, port 1 may still be under pressure for a longer period of time.

Protect yourself and others by not removing pressurized connections and wear

appropriate personal protective equipment when working!

Depressurize the system before carrying out any work

Have all work carried out by Pneumatics specialists

Warning! - Clogging of silencers

Blockage of the silencers can lead to malfunction of the valve

Ensure appropriate air purity

Warning! - Risk of injury due to noise

Operate the valve only with suitable silencers

Always wear hearing protection when working

Warning! - Risk of injury due to insuficient qualiication

As the operator, make sure that work is only carried out by qualiied specialist personnel

Train the operating personnel comprehensively in safety issues

Have electrical installations carried out by qualiied electricians only

CAUTION - Risk of burns due to hot surfaces

After longer operating times or at high pressures, considerable heat may be

generated at the solenoid. Danger of burns when touched

4. Basic function

4.1. General Description

4.2. Application

4.3. Function

The VP23 is a digital proportional pressure regulator that uses an electronic setpoint (analogue voltage/current or IO-Link

process data) to control the valve output pressure. The pressure is kept constant even if the medium (compressed air or

neutral gases) is consumed. The actual pressure value is reported back to the user as a voltage output and current output or

as IO-Link process data.

The VP23 allows the stepless adjustment of a pneumatic pressure. This can be used to control or regulate the following

processes: Speed, position, low, force, control of pneumatically actuated control and metering valves.

The valve operates with a closed control loop in which the outlet pressure is constantly detected by the pressure sensor and

compared with the speciied setpoint. If the outlet pressure is lower than the pressure set by the set point or if a higher

pressure is required, the force on the spool is increased via the electric proportional solenoid. A connection is made between

port 1 (inlet pressure) and port 2 (outlet pressure) until the outlet pressure is equal to the speciied set point. If the outlet

pressure is higher than the pressure set by the set point or if a lower pressure is desired, the force on the spool is reduced by

the electric proportional solenoid. A connection is made between port 2 (outlet pressure) and port 3 (vent) until the outlet

pressure is equal to the speciied set point. In addition, after switching off the supply voltage, the last set output pressure is

vented down to 0 bar.

Option: The IO-Link interface allows the user to not only control the output of the device, but also to adjust operating

parameters and monitor various performance feedback such as current output pressure and operating hours.

5.1 Block Diagram of the Valve Function (3/2 way)

5.2 Operating Medium

Port 1: System (input) pressure

Port 2: Working port (outlet pressure)

Connection 3: Venting

The pneumatic connections are marked with numbers and preferably have the following function and low direction: Flow

direction: 1 => 2 (consumer pressure build-up), 2 => 3 (consumer pressure reduction, venting). Without current the pneumatic

connection 2=> 3 is open.

Connection size: lange-mounted version with connecting plate G 1/4, G3/8, G1/2, G3/4

Filtered, oil-free and lubricated condensate-free compressed air or neutral gases (non-lammable).

Filtering of the supply air (50 µm) is recommended. When using lubricated compressed air, the dynamics and service life can

be inluenced by lubricants and their additives.

Medium temperature: -5 ... 50°C ( 23 ... 122°F) (non-condensing)

To prevent parts from freezing, the compressed air must be free of moisture below 2°C ( 35 °F).

Caution!

When using lubricated compressed air, the dynamics and the service life can be inluenced by the lubricants and their

additives.

Caution!

Avoid sealing the screw connections on the connection plate with Telon sealing tape or other sealing material. Otherwise

sealing material residues could get into the valve body and lead to sluggishness and malfunction of the valve.

The maximum permissible inlet pressures depend on the pressure range:

Set pressure P2 Operating pressure P1 max.

0 (0,02) ... 2bar 7 bar

0 (0,1) ... 10bar 12 bar

0 (0.16) ... 16bar 17 bar

This device has an optional IO-Link communication interface that requires an IO-Link-capable module (IO-Link master) for

operation. The IO-Link interface enables direct access to the process and diagnostic data and provides the possibility to set

the parameters of the unit during operation. In addition, communication is possible via a point-to-point connection with a USB

adapter cable for parameterization purposes.

The IODDs required for coniguring the IO-Link unit and detailed information about process data structure

(VA and VS are galvanically isolated)

Nominally the VP23 is supplied with 24V DC. The max. permissible supply range is between 18 and 32 V DC (incl. residual

ripple). The electronics are protected against incorrect polarity of the supply and will not be damaged. However, higher

voltages can destroy the electronics!

Before connecting, make sure that the supply voltage is switched off.

Connect the device as follows:

Supply voltage UB or VA and VS with IO-Link: 24V nominal (18 to 32V DC)

Residual ripple max.: 10%

Current consumption UB or VA with IO-Link:

Max. at 24 V DC: < 2,0 A approx.

Static at 24V DC, 25°C and balanced (X=W): < 0,7A approx.

Current consumption VS with IO-Link at 24V DC: approx. 50mA

The power supply of the proportional directional control valves may only be operated via a supply with safe isolation

from the mains (PELV according to EN 60204-1, DIN VDE 0100-410, IEC 364-4-41, HD 384.4.41 S2, EN 60079-14).

Our policy is one of continued research and development. We therefore reserve the right

to amend, without notice, the speciications given in this document.

Note:

The device must be connected by a qualiied person. The national and international regulations for the installation of electrical

equipment must be observed.

The valve body must always be integrated into the equipotential bonding of the plant (grounding).

The actuator system (=valve solenoid) is activated from 18 V supply voltage. Although the current draw at 24V drops to <

approx. after 1 sec. 0.7 A is limited, peaks of up to 2.0 A can occur. This must be taken into account when designing the system

supply.

In the IO-Link version, the supply voltage of the valve actuator is ensured via a second channel (VA). The valve is therefore

connected via port class B. This must be taken into account when selecting a suitable master.

Power supplies often have electronic current limiting, the activation of which results in a reduction of the output voltage.

This allows the switch-off threshold of the actuator of the VP23 of 18 V to be undershot. Due to the then drastically reduced

current requirement of the valve (~0.08 A), the power supply voltage rises again above the switch-on threshold. This may

cause an undesired oscillation process!
