bis 100 l/min

bis 350 bar

The PDR10P is a 3 way spool type

proportional pressure reducing valve

with relief included. Its main task is to

keep the pressure at port 1 (consumer)

constant.

In the de-energized mode port 2 (pump)

is connected to port 1 while the pilot

stage is open. If the pressure at port 1

rises above the setting, dened by the

electrical control signal (de-energized

setting

≤ 5 bar), the pressure at port 2

is metered off to maintain the adjusted

setting at port 1.

As a function of the electrical control

signal the regulated pressure at port

1 can be changed steplessly. If the

pressure at port 1 rises above the

setting, port 1 is vented to tank at port 3.

Any pressure is directly additive to the

pressure setting.

Features

 Exposed surfaces zinc-plated and corrosion proof

 All valve parts made of high-strength steel with hardened and

ground components to ensure minimal wear and to extend service life

 Waterproof designed standard coil

 Excellent stability throughout ow range

 Excellent dynamic performance

 Screen protected measuring orice enhances safety

Response sensitivity: ≤ 1 % of maximum control current

Notes:

The PDR10P can also be supplied with an emergency pressure adjustment (version

–01M). This allows a mechanical pressure adjustment of the valve if the electrical signal

is interrupted. This adjustment should be used only in case of electrical failure since the

manual setting would be additive to the electrical setting and the danger of equipment

damage could develop.

In order to achieve optimal function, any trapped air should be vented with the bleed

screw on the face of the tube (not tted to version –01M).
