1. Introduction
Parker TPQ proportional throttle valves have an
integral electronic and requires only one sole elec-
trical common for the control system. Different flow
sizes are available to achieve an optimal adaption
for different applications.
Characteristics of Valve Driver
The described integral electronic driver combines
all necessary functions for the optimal operation of
the valve.Thanks to its excellent dynamic the valve
is usable within closed loop control applications.

For detailed information concerning pressure
fluids note VDMA-document 24317 as well
as DIN 51524 & 51502.
• Check the proper position of the valve ports
and the O-rings.
• Mounting bolts: use property class 12.9, DIN
912
Insufficient condition of the valve mounting
surface migth create malfunction!
Incorrect mounting resp. bolt torque may
result in abrupt leakage of hydraulic fluid on
the valve ports.
Y-port has always to be tied directly and
separately to tank!
Operation Limits
The valve may be operated within the determined
limits only. Please refer to the “technical data“
section as well as to the “characteristic curves“ in
the catalog.
Follow the environmental conditions! Unallo-
wable temperatures, shock load, aggresive
chemicals exposure, radiation exposure,
illegal electromagnetic emissions may result
in operating trouble and may lead to failure!
Follow the operating limits listed in the “spe-
cifications“ table!

Scope of Supply
Please check immediately after receiving the valve,
if the content is matching with the specified scope
of supply. The delivery includes:
• valve
• operation manual
Please check the delivery immediately after
receiving the shipment for apparent damages
due to shipping. Report shipment losses at
once to the carrier, the insurance company
and the supplier!
Mounting
• Compare valve type (located on the name plate)
with part list resp. circuit diagram.
• The valve may be mounted fix or movable in
any direction.
• Verify the mounting surface for the valve. Une-
veness of 0.01 mm/100 mm, surface finish of
6.3 µm are tolerable values.
Keep clean valve mounting surface and work
environment!
• Remove protection plate from the valve mounting
surface

The connecting cable has to comply to the follow-
ing specification:
Cable type control cable, flexible,
7 conductors, overall braid
shield
Cross section min. AWG16
Outer dimension 8...12 mm
Cable length max. 50 m
For cable lengths > 50 m consult factory.
The connection cable is coupled to the female
connector by solder joints.
Skinning lengths for the connecting cable:
Electrical Connection
The electrical connection of the valve takes place
by one common cable, which is coupled to the
integrated electronic driver by a central connector
assembly.
The connection requires a 6 + PE female connector
EN 175201-804.
Female connector (ordering no. 5004072)
Do not disconnect cable socket under tension!

Electrical Interfacing
Supply Voltage:
The supply voltage for the valve has to cover the
range of 22...30 V. The residual ripple may not
exceed 5% eff.
The applied power supply must comply to
the relevant regulations (DIN EN 61558)
and must carry a CE-mark. The operating
voltage for the valve must be free of inductive
surges.Do not exceed the max. value of 30V!
Non-observance of this rule may result in
permanent damaging of the valve.
The increased inrush current of the valve
should be considered when selecting the
power supply. A stabilized power supply with
overcurrent limiting feature should not be
used.Due to the inrush current of the valve the
current limit circuit may respond prematurely
and create problems during energizing of the
supply voltage.
The operation of the valve is blocked if the
supply voltage polarity is interchanged.
Each valve requires a separate pre-fuse
of 4 Amp time lag. Non-observance of this
instruction may create irreparable damage
of valve resp. incorporated system parts.
The shielding has to be assembled according the
outline below:
The backshell nut of the cable gland has to be
tighten with a suitable tool.The target value for the
tightening torque is 4 Nm. Tighten the cap nut with
a torque of approx.5 Nm after attaching the female
connector on the socket outlet.
Incomplete tightening of backshell nut resp.
cap nut may result in automatic release of
the connection as well as degradation of the
water tightness.
Follow the“instructions for use“ for installation
of female connectors made by other kind of
brands!
The cable connection to the female connector
has to take place by qualified personnel! A
short between individual conductors resp. to
the connector housing , bad soldering as well
as improper shield connection may result in
malfunction and breakdown of the valve.
The mounting surface of the valve has to be
carefully tied to the earth grounded machine
frame. The earth ground wire from the valve
connecting cable as well as the cable shield
have to be tied to the protective earth terminal
within the control unit. It is necessary to use
a low ohmic potential connection between
control unit and machine frame to prevent
earth loops (cross section AWG 6).
