Safety Circuit, Holding the Datum Point
By using non-leak valve, non-leak pilot check valve, it allows to secure safety.
Since the non-leak vale and the non-leak pilot check vale can hold pressure even if power is lost,
there is no reason for concern that the workpiece falls off.

(Non-leak function allows to hold theposition for a long time without leakage.)

The Reliability of Non-Leak Function
The following graph shows the data analysis of the oil temperature, the amount of time and the change in pressure
while hydraulic pressure is disconnected from power source. Due to temperature change, maintained pressure changes
but not due to leakage. You can set the hydraulic circuit more stable when combined with the accumulator.

Hydraulic pressure of sealed circuit disconnected from hydraulic source by non-leakvalve, etc. is significantly affected by ambient temperature change and supply oil
temperature change. (Especially when using a motor pump, high temperature oil is
supplied and the temperature rapidly decreases after sealing.)
Although it differs depending on the amount of air mixed, product, piping/hose

Note : 1. If the flow volume of the incoming pressure side is too much, there is a possibility that the proper sequential procedures would not work.
In this instance, use a flow control valve to adjust flow volume from the pressure source.

Example of a Combination of BLS and BLB
Operating Procedure (When clamping)
1. Supply hydraulic pressure.
2. The hydraulic pressure passing through the BLB, starts the support action of Work Support.
At this time, hydraulic pressure does not reach the actuator side because of BLS.
3. When hydraulic pressure inside the system has exceeded the set pressure of BLS, the hydraulicpressure is supplied to the actuator to lock a workpiece.

Actuator
BLS/BLGOperating Procedure (When releasing)
1. Shut off hydraulic pressure supply.
2. Pressure reduction of BLS/BLG starts right after the hydraulic pressure supply is shut off andthe actuator retracts to release the pressure.
3. BLB reduces hydraulic pressure inside Work Support in proportion to the pressure difference (1:20)
between the incoming side (P port) pressure drop and the outgoing side (cylinder port) pressure.
Therefore, workpiece and fixture damage due to the remaining pressure can be prevented because
the workpiece is released after the actuator thrust becomes zero.

What is an accumulator?

Circuit Symbol

When a fixture is disconnected from the hydraulic pressuresource (closed circuit), with the change in volume of hydraulicfluid due to temperature changes, there will be pressure
increase and/or decrease.
Accumulator avoids damage and deformation of a machine※ A filter is not built in each port. Please sufficiently perform flushing ofand workpiece caused by pressure increase, and falling of

piping and fitting to prevent contaminants such as cutting chips fromworkpiece caused by pressure decrease.

What is a Pressure Indicator ?

Circuit Symbol

The circuit pressure of a fixture that is disconnected fromthe hydraulic power source can be detected by using
the pressure indicator with a sensor and/or a switch.
It enables to detect operations and errors of an automatic
control system.
※ A filter is not built in each port. Please sufficiently perform flushing of
piping and fitting to prevent contaminants such as cutting chips fromentering the circuit.

AU
Mode l AU -M
Mode lContinuous discharge booster that has
no limitation for the outgoing side circuit capacity
Actuator is made in a compact size by boosting pressure.
High pressure hydraulic power source is not needed by partial boosting pressure.

What is a Continuous Discharge Booster?
Boost incoming supply pressure by the back and forth action of piston and using bypass to get the boosted pressure
to the outgoing side.
There is no limitation in the outgoing side circuit capacity because it continuously discharges the pressure so it is the bestfor multiple actuator or big circuit volume.
There are modular option and it can be attached to modular valve.

Continuous Discharge Booster

m od e l AU

Cautions (AU)< Cautions (Common)＞1. Discharge flow decreases as pressure on outgoing side increases. (Refer to Flow Characteristic Graph.) Please keep in mind that
if there is larger load when an actuator on outgoing side strokes, the stroke time will be longer due to the decrease of discharge flow.
2. It cannot be pressurized properly if using a device with leakage in outgoing side circuit.
(Since a general modular solenoid valve has internal leakage, do not connect it to P2 port.)
3. Due to the mechanical structure, there is always internal leakage between the incoming port (P1) and the pilot port (D)(for modular model, between the pressurizing incoming port and T port). Please pay attention to the following notes.
・ When using a balance-stop pump (AA/AB/AC Pump manufactured by KOSMEK) as hydraulic power supply, the pumpdoes not stop in balance due to the internal leakage of AU, leading to continuous operation and reduction in pump life.
・ When supply pressure decreases or stops temporarily, pressure in the circuit after the outgoing port (P2) (for modular model：pressurizing outgoing port) of AU will be maintained by non-leak function. However, pressure in the circuit before P1 port
will not be maintained due to the internal leakage between P1 port and D port.
4. Stop hydraulic supply before disconnecting from hydraulic power source with auto couplers, etc. (Refer to Reference Circuit.)
5. Depending on incoming supply flow rate, circuit volume on outgoing side etc., surging may occur on incoming supply side.
This may result by increasing too much set pressure on outgoing side.
In that case, please prevent surging by installing accumulator or reducing incoming supply, etc.
6. If installing multiple numbers of AU to a low pressure hydraulic unit with high pressure supplied to a circuit, pressure fluctuation
will be much larger, causing unstable pressure supply.

< Cautions for Piping Option＞
1. Although each port is equipped with a filter, in order to maintain high pressure in the outgoing port (P2) at idle state ofpressure supply to the incoming port (P1), the piping and fitting should be thoroughly cleaned before use.
2. Tightening with excessive torque leads to malfunction. (Maximum) tightening torque should be as shown below.
Model No.

Bolt Size

Tightening Torque (N･m)AU2□□1-0

M6×1

MAX. 10< Cautions for Modular Option＞
1. Although the boosting ports (A1/A2 port for AU25□0-0MA, B1/B2 port for AU2□0-0MB) are equipped with a filter, the piping andfitting should be thoroughly cleaned before use.
2. When using Three-position solenoid valve, select ABT connection as the neutral position port model.
Pressure in outgoing side will be released when using a model(closed center, etc.) that supplied pressure in P port
flows into A or B port due to internal leakage when shifting

A B

AB

P T

P T

to neutral position at outgoing pressure maintained state.
3. Make sure that hydraulic pressure is supplied to the boosting port (A1 or B1) after the actuator on the outgoing side is completely released.
If pressure is supplied during release when there is still pressure (back pressure) remained in the boosting port, boosting time will be longer.

3. ★1 BEP Non-Leak Pilot Check Valve is a bypass circuit of AU. When the action speed of a cylinder is insufficient due to AU passage area,

it can be accelerated by providing the bypass circuit which increases the amount of oil pass on both lock and release sides.
4. ★2 BEP Non-Leak Pilot Check Valve is an example when maintaining hydraulic pressure at released state.

5. Non-leak circuit will not work when connecting an actuator, which is not to be boosted, to P1(R) port since there is internal leakage
between P1(R) port and D port. Please design another circuit. (Refer to Common Cautions No.3.)

Cautions
1. Excessive amount of supply oil in the incoming side leads to malfunction of BU Booster.
Provide a flow control valve with check valve just before the incoming side port, or adjust the flow rate on hydraulic pressure source side.
2. A large amount of air mixed in the outgoing circuit leads to boosting failure. If it does not work properly, release air from the circuit.
3. A large volume of oil capacity in outgoing circuit leads to boosting failure.
Refer to the outgoing circuit capacity shown in Allowable Circuit Capacity Curve.
4. Using hydraulic hoses in outgoing circuit may result in insufficient boosting because the volume changes during boosting.
Please use steel pipes as much as possible referring to the discharge rate of boosting process shown in specification.
5. Installing an accumulator in outgoing circuit may result in boosting failure by the similar reason. In case of using an accumulator,
please select a proper one referring to the outgoing circuit capacity shown in Allowable Circuit Capacity Curve.
6. It is recommended to install a pressure gauge. It is easy to check the boosting condition by installing a pressure gauge on the outgoing circuit.
7. Do not install a flow control valve to an actuator on outgoing side. It may be boosted before the actuator completes operation leading toboosting failure.

Cautions (BSP)
1. Please note that pressure will be decreased by oil temperature drop when stopping pressure supply to A1(B1) port andmaintaining pressure on A2(B2) port side.
2. The pressure relief valve is used for relieving volume of hydraulic pressure which is increased by oil temperature rise.
It cannot be used for reducing supply pressure that is out of relief set pressure range.
3. When using with pressure compensating valve, if there is back pressure generated in T port, it cannot be relieved properly.

1）Check the Usable Fluid● Please use the appropriate ﬂuid by referring to the Hydraulic Fluid List.

ISO Viscosity Grade ISO-VG-32

Maker
Showa Shell Sekiyu

2）Procedure before Piping● The pipeline, piping connector and ﬁxture circuits should be cleanedby thorough ﬂushing.
● The dust and cutting chips in the circuit may lead to ﬂuid leakage
and malfunction.
● There is no ﬁlter provided with Kosmekʼs product except for a partof valves which prevents foreign materials and contaminants fromgetting into the circuit.
3）Applying Sealing Tape
● Wrap with tape 1 to 2 times following the screw direction.
● Pieces of the sealing tape can lead to oil leakage and malfunction.
● Please implement piping construction in a clear environment toprevent anything getting in products.

4）Air Bleeding of the Hydraulic Circuit● If the hydraulic circuit has excessive air, the action time may become
very long. If air enters the circuit after connecting the hydraulic port
or under the condition of no air in the oil tank, please performthe following steps.
① Reduce hydraulic pressure to less than 2MPa.
② Loosen the cap nut of pipe ﬁtting closest to the clamp by one full turn.
③ Shake the pipeline to loosen the outlet of pipe ﬁtting.
Hydraulic ﬂuid mixed with air comes out.

④ Tighten the cap nut after bleeding.
⑤ It is more eﬀective to release air at the highest point inside
the circuit or at the end of the circuit.
(Set an air bleeding valve at the highest point inside the circuit.)5）Checking Looseness and Retightening● At the beginning of the machine installation, the bolt and nut may
be tightened lightly. Check the looseness and re-tighten as required.
