RS 210
Key valve features
RS 210 is a sectional open center valve,
designed for
max. operating pressures
up
to 300 bar and max. pump ows up to
70 l/min.
RS 210 is available with 1 to 10 working
sections per valve assembly.
The valve can be used in different
systems for parallel as well as
tandem circuits. It is designed with
an open center for xed and variable
displacement pumps.
The valve can be operated manually,
with cable or by pneumatic and electro-
pneumatic or electro-hydraulic remote
control.
RS 210 offers excellent operating
characteristics because of the
specially designed spools for different
applications.
Low and uniform spool forces are the
result of careful balancing of the ow
forces.
Q-function
The ow control (Q-function) of the inlet
section by-passes the major part of the
pump ow to tank when the system is
idling, still giving access to full pump
ow when the services are operated.
Besides greatly reducing heat generation
this also provides improved operating
characteristics.
Applications
The RS 210 is ideal for applications
where you need excellent control
characteristics such as cranes,
excavators, back-hoe-loaders, skid
loaders and tipping gear.

Dimensions inlet section type I02Q – with by-pass and electrical unloading
I02Q is an inlet section with ow control, main relief valve
and unloading function.
When the system is idling a small regulated ow passes
the center gallery of the valve. Excess pump ow is routed
directly to tank.
The regulated ow is dened by the ow control valve
FKA283 and the metering orice PF.
When a spool is operated the whole pump ow is instantly
available for the user. The low center gallery ow during
idling conditions reduce pressure drop P – T through the
valve body, and this facilitates higher pump ow without
negative inuence on the spool forces and heat generation.
I02Q also is equipped with main relief valve TB12, which
together with ow control FKA283, function as a pilot
operated main relief valve. The Q-inlet can be equipped
with a solenoid operated valve for electrical unloading.
The available metering orices are PF11 and PF12.
In combination with FKA283 they provide:
PF11: 25 l/min; PF12: 28 l/min
A lower ow creates less pressure drop P – T.
A spool that matches the ow improves the operating
characteristics.

Electrical unloading valve
The electrical unloading valve is a 2-way, normally open,
solenoid type cartridge valve. It is an option in inlet sections
I02Q, I06Q and I01E.
It is intended for emergency stop and for pressure drop / heat
generation reduction.
In Q-inlets a de-energized unloading valve drains the pilot
circuit so that the FKA283 spool dumps the whole pump ow
directly to tank.
In inlet I01E a de-energized unloading valve dumps
the whole pump ow to tank.

Spools
The RS 210 spools are available in variety of ows and styles to accommodate most design requirements.
Since the development of spools is a continuous process and all available spools are not described in this data sheet,
contact HYDAC for advice on choosing spools in order to optimize your valve conguration.

Electro-hydraulic remote control
As a part of the RS210 modular system is also a sub system
for electrical remote is available.
The main parts in that system are a pilot supply unit, spool
controls with 12 or 24 Volt proportional solenoid operated
valves and piping.
The spool control is for control of 3-positional spools. It is
possible to use the remote controled spool controls with inlets
of type “Q”.
The pilot supply unit builds up supply pressure but includes
also a pressure reducing valve that limits the supply pressure.
The spool control is designed as a double acting cylinder
assembled on the valves A-side and the spool ends on the
B-side are available for manual over ride by a lever.
The spool controls are designed with an interface for internal
connection between the controls of both supply pressure as
well as return ow.
The valve can be delivered complete by assembled with spool
controls, pilot supply and piping. The modular and easy to
handle design makes the remote controls suitable also for
complete assembly on existing valves.
Pilot supply block
The pilot supply block includes a pressure build up valve that gives an
initial pressure depending of ow but in the range of 10 to 14 bar. That
pressure is enough for start of the maneuver of the spool that will raise
up the system pressure. The supply pressure to the spool controls is
limited to 23 bar which is the pressure set for the pressure reducing
valve. Both the supply to the spool controls and the return from them
is piped to the block.
The spool control shall be assembled on the valves A-side.
The design is a double acting cylinder that positions the spool
against a spring. The proportional solenoid valves are available
both for 12 Volts as well as for 24 Volts and for PWM supply.
The spool controls can also be delivered with a spool position indicator.

TBD121 is a direct acting relief valve for
the secondary circuit. It is adjustable and
sealable.

Anticavitation valve SB160
The anticavitation valve ensures that,
in the event of a lower pressure in the
cylinder port than in the tank, oil can be
drawn from the system oil tank to the
consumer.

Typical hydraulic diagrams
The circuit diagram shows a complete RS 210 valve,
4 sections with an inlet with ow regulator (“Q-inlet”) and
completed with pilot supply and spool controls for remote
control.
Note the separate piping to tank for the return ow from the
remote control. It is required to pipe up the system in that
way in order to avoid high pressure and pressure peaks
in the return line.
Hydraulic diagram for a 4-sectional RS 210 valve.
It is tted with a Q-inlet with electrical unloading.
The rst 3 sections contain 3-positions spools for double acting
functions and port relief and anticavitation valves.
The 4th section contains a 4-position spool for double acting
functions with oat position in position 4. The outlet section gives
possibility for high pressure carry-over (if S1 is plugged).
