Proportional Pressure Regulators
PQ1
-
Description:
The pneumatic proportional valve produces outlet pressure in
proportion to an electrical command input signal. It comprises
a complete closed loop servo system consisting of valves,
manifold, housing and electronic controls.
Single_loop:
Pressure is controlled by two solenoid valves. One valve
functions as inlet control, the other as exhaust. The pressure
outlet is measured by an internal pressure transducer which
provides a feedback signal to the electronic controls. This
feedback signal is compared with the command input signal.
Any difference between the two signals causes one of the two
solenoid valves to open, allowing flow into or out of the system.
Accurate pressure is maintained by these two valves.
Accuracy:
Linearity / Hysteresis = ± 0.15 % FS
Response sensitivity = < 0.1% FS
Repeatability = ± 0.02% v.E
Total accuracy = ± 0.2 % V.E.
Supply_voltage: 15...24 V DC, residual ripple < 10%, with reverse voltage protection
Command signal: 0-10V, 4-20mA as an option
PQ2
-
Description:
The pneumatic proportional valve produces outlet pressure in
proportion to an electrical command input signal. It comprises
a complete closed loop servo system consisting of valves,
manifold, housing and electronic controls.
Double_loop:
The servo valve expands in single loop operation by combining
an additional feedback from an external sensing device with the
internal transducer. The external sensor provides information
on the control status.
The PQ2 then compares the command signal with the second loop feedback signal. Should there be a difference in the signal
comparisons, the servo valve will make adjustments to the
internal loop to bring the system into balance. This provides
accurate final outlet. The acceptance of electrical feedback from
an external sensor enables precise control of conditions such as
pressure, force, torque, position or flow.
External_pressure_transducer:
Any pressure transducer for 0-10 V and 4-20 mA output signal and
suitable for 15-24V DC supply voltage can be applied.
An appropriate coupling socket plus cable is required.
Supply_voltage: 15...24 V DC, residual ripple < 10%, with reverse voltage protection
Command signal: 0-10V, 4-20mA as an option
PQ3-PQ6
-
Description:
Closed loop electronic pressure regulator consisting of two
solenoid valves, an internal pressure transducer, and an
electronic control circuit mounted to an integral volume
booster. The pressure is controlled by activating the
solenoid valves, which apply pressure to the pilot side of
the volume booster.
Single_loop:
Pressure is controlled by two solenoid valves. One valve
functions as inlet control, the other as exhaust. The pressure
outlet is measured by an internal pressure transducer which
provides a feedback signal to the electronic controls.
This feedback signal is compared with the command input signal.
Any difference between the two signals causes one of the two
solenoid valves to open, allowing flow into or out of the system.
Accurate pressure is maintained by these two valves.

Description:
The pneumatic proportional valve controls the outlet pressure
in proportion to an electrical command input signal.
It comprises a complete closed loop servo system in a compact
monoblock assembly with proportional solenoid valve, electronic
regulator and internal pressure transducer.
In the process, the outlet pressure is transformed into a
proportional electrical signal and compared with the input signal.
If the outlet pressure exceeds the preset setpoint, the valve
exhausts down to the pressure desired.
The valve has no constant bleed.
At absence of input signal or supply voltage the valve exhausts.
The power supply of the setpoint potentiometer is provided by the
proportional valve via connector pin number 5.
Pressure_transducer:
Open transducers = 100 mbar, 500 mbar, 1 bar and vacuum
Application_examples:
Proportional pressure regulators are being used for blowing machines, ultrasonic equipments, testing machines, painting systems, contouring systems, laser welding machines, textile machines, cheese presses, pneumatic brakes, clamping devices and medical engineering.

Description:
2-way proportional flow valve controls the volume flow of
maximum 1185 l/min for air in proportion to the input signal
of 0 to 10 V or 0/4 to 20 mA. The proportional valve and the

The nominal width of the orifice following the proportional valve
should not be smaller than the nominal width of the valve.

categorically avoided!

Pressure Boosters
AB
-
Description:
The pressure booster doubles the system pressure of e.g. 5 bar
to an outlet pressure of 10 bar. The pumping force of two
cylindrical chambers compresses the air down to the set outlet
pressure within the third chamber while the fourth chamber is
vented. Upon reaching the outlet pressure it is turned off, when
falling below it is turned on automatically. Pressure boosters
are used for occasional demand of compressed air.
Media: lubricated and 50 µm filtered compressed air
Mounting_position: any
Drive:
double piston intensifier, ratio 1 to 2
Reversing, check and swichting valves provide for automatic control.
Life time approx. 20 million switching cycles.
Inlet_pressure_P1: 2...8 bar
Outlet_pressure_P2: 4...16 bar
Air tanks are recommended. They compensate pressure fluctuations and allow short-term high volume flows. See circuit.
Tank filling time is a measure of booster performance. To reduce
the filling time of the tank, it has to be prefilled with input
pressure P1. See circuit.
Temperature_range: -5 °C to 50 °C / 23 °F to 122 °F
Cylinder: anodized aluminium

pressure has been reached. Service life 3 million cycles, full
load operation 12 min max. per hour.
Media: lubricated, unlubricated and 50 µm filtered compressed air or nitrogen
