Our solenoid valve consists of two sections； one is the valve partmade of highly inert plastics like PTFE or PEEK, which opens andcloses a flow path. The other is the actuator made of a coil andmetallic parts, driving the valve part. In order to preserve the purity of
the fluid, a diaphragm is installed between the two sections in ourisolation valves. The diaphragm prevents the fluids from flowing into
the actuator and protects the metallic parts from being corroded. Also,
metal dust generated in the actuator does not contaminate the fluid.
This structure is ideal for analytical and diagnostic applications which
are sensitve to particles. It is also suitable for handling acids andchemicals which erode metals.
By reducing the size of these isolation valves, we have been able toreduce the dead volume, improve the control of the pumping volume,and reduce the installation area, thereby improving accuracy andavoiding wasting chemicals and solvents.

Pumping Volume
The diaphragm produces a pumping effect on the fluid as the valve opens and closes. As somevalve models pump several microliters of fluid at one time, the pumping volume forms a negative
factor in metering an accurate fluid volume, and also in preventing fluid from dripping from adispensing nozzle.
Some of the valve models we provide have remarkably small pumping volumes due to theirunique internal structures or miniaturized dimensions. The EXAK series has a distinctive design
called a “zero-pumping-volume structure” that allows the pumping volume to run 100 times
smaller than our standard valves. Rocker valves（page 8）and non-diaphragm inert valves（madeof inert materials like stainless steel）have very small pumping volumes due to no volumetricchange in the valve chamber during an operation. We also provide slider valves（page 12）withpumping volumes that have been ultimately reduced to an immeasurable level.

Diaphragm

Problems can arise with PTFE diaphragmvalves when scratches on the seal partof the valve, due to dust or crystals in
the fluid, cause the valve to leak. Takasago
offers an optional "Soft-seal" to protect
the sealing surface from being scratchedby covering it with perfluoroelastomer,
which is a special elastomer that has
outstanding resistance to most chemicals
and solvents. The chemical inertness ofthe perfluoroelastomer is almost equal
to PTFE. It has a high reputation for use
with chemicals in analytical or semi-conductor
industries. FPM is also available for theSoft-Seal material.

Figure 3

Applicable models A diaphragm solenoid valve normally has a doughnut-shaped space right under the diaphragm, through which fluids

flow to the outlet port（Figure 1）. This space, often called a "valve chamber", works as excess internal volume to waste
solvents and samples. Fluids tend to stay in this dead space and therefore decrease the purity of each fluid. In addition,（2-way type only） air bubbles may be trapped in this valve chamber and can have a negative effect on analytic accuracy. To conclude a
valve chamber causes various undesirable results for applications. To overcome these problems, Takasago has
・MTV Series
designed the Zero-Internal-Volume Valve, in which a special structure is employed to eliminate the valve chamber
・MLV Series （Figure 2）. On opening, the diaphragm is lifted and the space is formed for the fluid to stream（Figure 3）.
（Note）This Zero-Internal-Volume structure is patented.

Coil Temperature

N.C. typeIn the case of a conventional (e.g. N.C. - Normally Closed)solenoid valve, continuous energization is required tomaintain open status. The latching solenoid does not requirea power supply for the purpose of maintaining open statusthrough the utilization of a permanent magnet. Suitable forapplications where the power consumption and the effect oftemperature on a fluid is a concern.

Latching typeTime

Holding Voltage and “Hit & Hold” Circuit
Once switched to ON-position by energizing at the rated voltage, a solenoid valve can hold the ON-position status even after the applied
voltage is dropped to a lower voltage. For example, in case that a 2-way normally closed valve with a rated voltage of 24 VDC is switched
to ON-position, it can hold the ON-position even after the applied voltage is dropped to around 10 VDC（Holding Voltage）. Using thischaracteristic, various benefits are achieved, such as low power consumption, reduction of coil heat-generation (see graph below),
improvement of response time, increase of operating pressure, minimization of size, etc. This requires you to control the applied voltage.
As an alternative to controlling the voltage at the equipment side we can offer you a “Hit & Hold” circuit, which can be simply attached toa valve. This circuit automatically drops the applied voltage to a lower value after a very short period of time (Inrush Time).

Multi-layer Bonded Manifold

Bonded PTFE Manifold

Iluminated
These multi-layer manifolds are made by bonding layers that have channels engraved on the surface. The result is a highly
integrated manifold with freely curving channels that could not be fabricated through a conventional drilling process. The bonding
process does not use any adhesive in order to utilize the pure characteristics of each material. Materials available are PMMA,
PC, ULTEM®, etc. Only Takasago works with PTFE, the material with a very high chemical compatibility, in this way.

Molded Quaternary Valve

Chemically Inert Pinch ValveA quaternary valve, in which the four channels fromthe valves all join at one point and connect to thecommon port, requires a high processing accuracy
at the junction of the channels. Thus the manifold
bases of almost all conventional models, including
those of other manufacturers, are manufactured bymachining, which results in an increased cost. Withadvanced molding techniques, TAKASAGO has
achieved the molding of this junction in PEEK,
enabling us to provide our quaternary valves atprices conventional models cannot match.

Having threaded ports for plastic tubing, this product looks like an ordinary solenoid valve, but in fact
it is a type of pinch valve that uses FPM tubing
internally. The valve excels in fluid exchangeability
due to its simple flow structure with almost no deadvolume. Furthermore, the FPM tubing gives thevalve high chemical inertness.

Various Unique Products
Solenoid-driven Slider Valves●2-way (N.C.)
This is a kind of shear valve in which a shutter called a“slider” moves vertically and shuts off the flow path. The
pumping volume* and the dead volume are reduced toalmost zero, preventing reduction of accuracy in analysis or
fluid dispensa tion. It fea tur es an ex cellent fluid
exchangeability compared to a diaphragm solenoid valve
due to its almost linear flow path and very small internal
volume.

This pump utilizes an electro-osmotic flow induced byapplying an external electric field on a charged solid-liquidinterface of narrow channels inside a porous material.
Features・Zero-pulsation flow and no operating noise due to no
mechanical parts.
・Small size（a few millimeters）and lightweight（a few grams）.
・High pressure. Potentially more than 1MPa.

・Adjustable flow. Linearly proportional to applied voltage.

The Electro-osmotic Pump（EO pump）can directly discharge
only ethanol, methanol or deionized water. For discharging
other liquids, indirect pumping is recommended. Its
mechanism is to deliver ethanol through an EO pumptowards a separator（ex. a diaphragm or a gasket）, driving itby the increased fluid pressure and discharging the target
liquid accordingly. We offer indirect pumping units onrequest.

This is just an example of our integrated fluid control systems. Other microfluidic systems can be designed and manufactured
in accordance with your requirements.
This system is jointly developed with Aquatech Co., Ltd. and Fukoku Bussan Co., Ltd.

Micro Needle Valve＜ Example of Reduced Pulsation ＞
By incorporating a micro needle valve on the
discharging side of a piezoelectric micro pump, thesignificant pulsations created by the low flow operation of a piezoelectric pump are eliminated and a low
flow rate with almost no pulsation can be achieved.
The graph below is an example of this remarkablereduction in pulsation. Pulsation can also be reduced
when combined with other kinds of pumps, such as
peristaltic pumps.

Example of Microfluidic Control Module

Microfluidic Chip
FV Series

Electro-Osmotic Micro Pump

Pen Type Syringe Pump
Peristaltic Pump

This is a demo module in which a plastic chip is prefilled with a reagent. It is constructed from a pen type syringe pump and an ultra-small
inert 3-way valve.
This module demonstrates the basic processes including sample introduction, mixing with a reagent, and detection, by using a chip with
Y-shaped internal channels. A sample is introduced into the chip by an ultra-small peristaltic pump and, after being metered in accordancewith the length of the channel, transported and mixed with the pre-filled reagent by a pair of electro-osmotic pumps. The flow is swicthedby ultra-small valves. The chip is designed to be disposable and can be easily fixed on the module by the holding plate.

Solution Provider
Reagent-prefillable Disposable Fluidic Systems（❶Roller Pump Type, ❷Syringe Pump Type）

These systems integrate every necessary function of POCT into a single module. Once a reagent-prefilled module isloaded on the system, the pump discharges the prefilled reagent from the reservoir and draws a sample into themodule from the sample-in port to mix them together. The module has another closed reservoir for waste, simplifying the disposal of chemicals. Time-consuming tasks are eliminated. Two types of pumps are available as shown in
the above pictures: ❶Roller Pump and ❷Syringe Pump. Customisation is possible to match your requirements.
