Sauer-Danfoss valves are designed
to be flexible, which allows them to meet virtually
any need. The modularity of our proportional and
directional valves, the variety of our cartridge
valves - as well as the flexibility of our electrohydraulic
products - allows Sauer-Danfoss valves to be used
in applications ranging from road building and
construction machinery to agriculture and forestry
equipment.
|
Our family of proportional valves includes three valve
series. The PVG 32, PVG 100 and PVG 120 are available individually
or as combined assemblies.
|
 PVG
32 is a hydraulic load-sensing valve designed
to give maximum flexibility. It is available in
many versions, from a simple load sensing directional
valve to an advanced electrically controlled load-independent
proportional valve. The module capability of the
PVG 32 makes it possible to build up a valve group
to precisely meet your requirements. The compact
external dimensions of the valve remain unchanged
whatever combination is specified.

General
features of PVG 32:
|
| |
- Max flow per section 129 l/min
(34 gpm)
- Max pressure per section 350 bar (5075 psi)
- Load-independent flow control
- Oil flow to an individual function is
independent of the load pressure of this
function
- Oil flow to one function is independent
of the load pressure of the other functions.
- Up to 10 sections per valve group
- Accurate flow controllability
- Open center versions for systems with fixed
displacement pumps
- Closed center version for systems with variable
displacement pumps
 Variety
of spool types (open, closed, float position,
etc.)- Interchangeable spools
- Variety of actuator combinations
- Integrated electronics, sensors and actuators
- Feedback transducers standard to provide optimal
control, regardless of changes in viscosity,
voltage or flow
- CAN-BUS option with the possibilities of implementing
intelligent control functions (ramp, adjustable
flow limiting, dead band compensation, etc.)
|
The PVG 100 is a post-compensated proportional valve, which utilizes proven, common hardware with the PVG 32 and PVG 120. It is a modular valve which provides a flexible platform to match system design requirements.
|
| |
General Features of the PVG 100:
|
| |
- Max flow per section 180 l/min (47 gpm)
- Max pressure per section 350 bar (5075 psi)
- Load-independent flow control regardless of flow supply conditions – Flow Sharing
- Oil flow to an individual function is independent of the load pressure of this function
- Oil flow to one function is independent of the load pressure of the other functions.
- Up to 8 sections per valve group
- Can be combined with PVG 32 in a Hybrid configuration
- Open center versions for systems with fixed displacement pumps
- Closed center version for systems with variable displacement pumps
- Variety of spool types (open, closed, float position, etc.)
- Interchangeable spools
- Variety of actuator combinations common with the PVG 32
- Integrated electronics, sensors and actuators
- Feedback transducers standard to provide optimal control, regardless of changes in viscosity, voltage or flow
CAN-BUS option with the possibilities of implementing intelligent control functions (ramp, adjustable flow limiting, dead band compensation, etc.)

Like
the PVG 32, the PVG 120
is a combined directional control valve operation
according to the load-sensing principle. Its module
capability makes it possible to build up a valve
group that matches specific requirements.
|
| |
General
features of PVG 120:
|
| |
- Many of the same features as PVG 32
- Max flow per section 239 l/min (63 gpm)
- Max pressure 400 bar (5800 psi)
- Up to 8 valve sections per group

 Sauer-Danfoss
manufactures mobile control valves for applications
up to 100 lpm(26 gpm). Typical uses include,
but are not limited to, controlling hydraulic
systems
in construction, agriculture, turf care and aerial
lift markets.
Our line of directional control valves are available
as monoblock, stack or mono-stack; series, parallel
or tandem. Monoblock valves are offered in one,
two and three section units. Stack valves can
have
as many as twelve sections. Mono-stack valves in
parallel circuit combine the lower manufacturing
cost of
a monoblock with the versatility of a stack valve;
two to six spools are standard. The mono-stack
design
eliminates between-section leakage and spool bind.

| |
Features:
|
| |
- Standard parallel circuit valves equipped
with handles
- Joystick control options
- Various check options (load, pilot-operated,
low-leakage)
- Range of port sizes
- Paint protection available
- Add-on spool section for applications requiring
cylinder ports (mono-stack option)
- Custom-designed valves available
|

Additional
features of CDS products:
|
| |
- Electrical and pneumatic control
- Hydraulic unlock actuation
- Relief valves with or without anti-cavitation
- Float spools
- Mechanical joysticks
- Cable controls
- Mid-inlet combiner/divider sections

 HIC
is short for Hydraulic Integrated Circuit. In
addition
to the standard range, blocks can be specially
designed to meet customer requirements. The use
of HICs substantially
reduces the number of external connections. Due
to their minimal installation time, compact size
and weight, HICs improve system performance and
simplify maintenance.
Sauer-Danfoss offers a range of motor-mounted
valve blocks to control the speed
and/or maximum torque of the motor. There
are countless
application possibilities in the mobile,
marine and industrial fields.
 Sauer-Danfoss
manufactures a wide variety of flow- and
pressure-regulating cartridge valves.
The range of pressure-regulating valves includes
direct acting, pilot-operated, sequence,
pressure reducing, and overcenter valves.
They allow
flow
up to 380 l/min (100 gpm) and pressures up
to 420 bar (6092 psi).
The range of flow-regulating valves includes
pressure compensated, flow dividers and combiners,
needle
valves.
 The
range of solenoid operated
directional control valves includes
two-way, three-way, and four-way two and
three position valves.
They allow flow up to 225 l/min (59 gpm)
and pressure up to 350 bar (5076 psi).
The range of electroproportional
valves includes pressure reducing,
relief and flow control valves They allow
flow up
to 75
l/min (20 gpm) and pressure up to 350 bar
(5076 psi).
In Spring of 2003, Sauer-Danfoss acquired a majority
share of Comatrol
S.p.A., Italian manufacturer
of hydraulic valves and HIC manifolds. In addition
to the valve products listed above, Comatrol contributes
a variety of components to
the wide range of cartridge valves and HIC manifolds.
