INTRODUCTION Moog Proportional Valves D92x Series
PRODUCT OVERVIEW
Moog D92x Series Valves are direct operated proportional
valves driven by two proportional solenoids. They are
equipped with integrated electronics and closed-loop
position control of the spool.
The valves are suitable for electrohydraulic control of
position, speed, pressure and force in open-loop and
closed-loop control systems.
The robust design provides for a high resistance against
harsh environmental conditions like high vibrations and
temperature.
These valves offer analog interfaces for command signal
and spool position feedback. They are however, equipped
with modern electronics with a digital core that offers high
energy efficiency while delivering high static and dynamic
control performance.

INTRODUCTION Moog Proportional Valves D92x Series
DESCRIPTION OF OPERATION
Valve Design
Moog D92x Series Proportional Control Valves are
closed-loop hydraulic products that are used in industrial
applications. These valves are electrical feedback valves,
which means that the position control loop for the spool is
closed by a position transducer and the integrated valve
electronics.
The spool (8) is deflected by two proportional solenoids
(5 and 11), one for each direction of movement. When the
electrical power is cut off, the spool is centered between
two springs (6 and 9). Spools are available with different
overlaps, so the valve configuration can be adapted for
specific applications.
The onboard electronics (3) is mounted on top of one of
the solenoids to create a compact and space-saving valve
shape. The electronics is uncoupled from the electronics
housing and therefore provides a high resistance against
vibrations and shocks.
Operation
An electric command signal (spool position set point) is
applied to the valve electronics via the main connector
(1). A position transducer (4) measures the actual position
of the spool (8). The electronics compares the spool
position and the command signal, and control the Pulse
Width Modulated (PWM) currents to the proportional
solenoids. If a control deviation occurs, the PWM currents
are changed to move the spool to the desired position.
Afterwards, the PWM currents are kept at a level that
holds the spool in this position.
Thus, the position of the spool is proportional to the
electric command signal.

FLOW CALCULATION
When the valve is open the resulting flow is dependent not
only on the spool position, (i.e. the opening cross section of
the valve), but also on the pressure drop at the individual
lands. When the valve is deflected at 100 %, it delivers the
rated flow with the rated pressure drop. The rated flow
of a proportional valve corresponds to a pressure drop of
5 bar (75 psi) per land, equating to 10 bar (150 psi) for two
lands. When a valve is opened at 100 %, the flow can be
calculated as a function of the actual pressure drop with
the aid of the formula below, or it can be taken from the
diagram.

When operating the valves close to these application
limits, it is necessary to drill the ports to the maximum
possible diameters (see „Port Pattern of Mounting
Surface“ on pages 10 and 15).
