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!

4. Mounting / Installation

Scope of Supply

Please check immediately after receiving the valve,

if the content is matching with the speciﬁed scope

of supply. The delivery includes:

• 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).
