1. DESCRIPTION
1.1. GENERAL
The HYDAC safety and shut-off block is
used to shut off and discharge hydraulic
accumulators or consumers.
It complies with the relevant safety
standards in accordance with
DIN EN 982 and the German industrial
safety regulations BetrSichV.
The Hydac pressure relief valve DB12 is
used on the SAF series. This is a direct-
operated pressure relief valve in poppet
valve construction with excellent opening
and closing properties. This version of
DB12 conforms to the requirements of the
Pressure Equipment Directive 97/23/EC
with CE marking and is supplied with a
declaration of conformity and an operating
manual.
Please read the operating manual!

1.1.1 Key to the circuit diagram 1.1.2 Product benets
The compact combination of components
considerably simplies the connection
of an accumulator or consumer to the
hydraulic system and provides the
following benets:
Minimum of space, maintenance and z
installation required. As all the individual
units are combined in one block,
considerably fewer pipe ttings are
necessary for installation
Considerable reduction in installation z
time.
All types of connections for various z
accumulator designs and makes
are available - imperial and metric
connections as well as manifold
mounted and weld nipple.
Additional valves such as pilot-operated z
check valves, ow control valves and
combined ow control and check valves
can be tted to the system connection P.

1.2. CONSTRUCTION
The SAF safety and shut-off block consists
of a valve block, an integral HYDAC
pressure relief valve, a main shut-off
valve and a manually operated pressure
release valve, and the necessary gauge
connections are provided in addition to the
tank connection.
In addition, an optional solenoid-operated
2-way directional valve allows automatic
discharge of the accumulator or consumer
and therefore of the hydraulic system in an
emergency or for shut-down.
1.3. PORTS
The safety and shut-off block has the
following ports:
S – Accumulator port
P – Inline port
(pump)
T – Tank port
M1 – Test gauge port
G 1/2 - ISO 228

This block is mounted on a front panel
with 3 off M8 screws. Ports "P" and "T" are
located on the mounting side.
Advantages:
The compact design means that the block
occupies a minimum of space and ensures
minimum maintenance.

5.6. SAFETY AND SHUT-OFF
BLOCK WITH 2-WAY
CARTRIDGE VALVE
(LOGIC ELEMENT)
This safety and shut-off block consists of
a valve block, an integral pressure relief
valve and a solenoid-operated 2-way
cartridge valve which replaces the main
shut-off valve.
Advantages:
In addition to its compact construction,
this model is capable of rapid switching to
control the oil ow.
5.6.1 Function when using 4/2
directional valve
When the 4/2 directional valve is in the
switching position shown (open when
de-energised), the spring chamber of
the logic element is pressurised via the
accumulator pressure; the path from P to S
is blocked and the hydraulic accumulator is
automatically shut off from the system. By
connecting the accumulator via the slip-in
orice in the pilot valve to the tank, it will
slowly discharge.
When the 4/2 directional valve is in the
crossed-over switching position
(energised), the spring chamber of the
logic element is discharged, the path from
P to S is opened and the accumulator is
charged.

5.6.2 Function when using 3/2
directional poppet valve
When the 3/2 directional poppet valve
is in the switching position shown (open
when de-energised), the spring chamber
of the logic element is pressurised via the
system pressure; the path from P to S is
blocked and the accumulator is shut off
from the system. When the 3/2 directional
poppet valve is in the discharge position
(energised) the spring chamber of the logic
element is discharged, the path from P to
S is open and the accumulator is charged.
If the pump breaks down or if it is switched
off, the 3/2 directional poppet valve reverts
to the "open when de-energised" position;
the accumulator pressure shuts off the
logic element via the shuttle change-over
valve and shuts off the accumulator from
the system.

6. DESCRIPTION OF DSV10
6.1. GENERAL
DSV10 as a
low cost alternative
to the SAF10
The 3-way safety block DSV10 is used
to shut off and discharge hydraulic
accumulators or consumers. It complies
with relevant safety standards in
accordance with DIN EN 982 and the
German industrial safety regulations
BetrSichV.
The HYDAC pressure relief valve DB12 is
used with the DSV series. This is a direct-
operated pressure relief valve in poppet
valve construction with excellent opening
and closing characteristics.
This version of the DB12 complies with the
requirements of the Pressure Equipment
Directive 97/23/EC with CE marking.
There are four different models:
DSV10M, z
manual discharge,
standard L-ball
DSV10M-T-ball, z
manual discharge,
T-ball
DSV10EY, z
manual/solenoid-operated discharge,
open when de-energised
DSV10EZ, z
manual/solenoid-operated discharge
closed when de-energised
The essential difference compared to the
SAF10 lies in the shut-off and discharge
function of the DSV10. On request we can
supply other models to cover almost all
applications, e.g. for aggressive media.
On request we can supply test certicates
to EN 10204 and quality test certicates to
DIN 55350, Part 18.
6.2. CONSTRUCTION
The DSV 3-way safety block consists of
a valve block with an integral HYDAC
pressure relief valve and a shut-off valve.
It has ports for the pump, pressure gauge,
tank and accumulator.
In addition, an optional solenoid-operated
2-way directional valve allows automatic
discharge of the accumulator or consumer.
Accumulator operation
Shutting off the system pressure
and simultaneously discharging
the accumulator
The DSV10 can be used as a cost-
effective alternative to the SAF10. Unlike
the SAF10, the DSV10 shuts off when
discharging simultaneously to the tank.

6.3. PORTS
The DSV has the following ports:
S – Accumulator port
(M33x2 DIN 3852 Part 3)
P – Inline port
(G 3/8 and G 1/2)
T – Tank port
(G 1/4)
M – Pressure gauge port
(G 1/4)
6.4. FUNCTION
When the accumulator is in operation the
change-over ball valve connects the pump
port with the accumulator. At the same time
the accumulator is monitored for pressure
via the built-in pressure relief valve.
By switching over the ball valve, the pump
port is shut off leakage-free on the inlet
side and the accumulator is discharged
simultaneously to the tank.
During switching all three ports (P, S
and T) are momentarily interconnected
(negative switching overlap). If a solenoid-
operated 2/2 directional poppet valve
is tted, automatic discharge is possible
(e.g. in the event of a power failure or shut-
down).
6.5. NOTES
Ball valves are not designed to be used as
ow control valves; therefore they should
always be either fully open or fully closed,
to avoid damaging the sealing cups.
To ensure correct functioning, pressure
and temperature specications must be
observed.

of lter elements guarantees correct
operation, reduces wear and tear and
increases the service life.
