Installation And Connection - YAMADA KGK-400 Series Instruction

4. Installation and Connection

4-1 Selection of metering valve
Select an appropriate metering valve by referring "Cylinder
Size" in the table. The size of a cylinder should be closest to
your desirable amount of a shot. If you want to have 0.3mL
and 2mL shots using the same metering valve, provide a
1mL cylinder for 0.3mL shots and a 3mL cylinder for 2mL
shots. Replace a cylinder depending on the amount you want
to dispense.
Especially where an accurate shot is required, it is not
recommended to use a large cylinder for a small amount of shot.
* A metering error varies among materials. Usually, it is between plus or minus 1.5 - 2%.
4-2 Installation
Install your metering valve as close as possible to the equipment or its inlet port you are going to work on. The
longer the connection is, the more the discharge amount from the outlet varies.
4-3 Connection
① Material Inlet
Connect the material inlet (Rc1/4) of your metering valve
and a material supply pump with a pipe or hose.
CAUTION: Material supply pressure to the metering
valve depends on viscosity of material.
The working pressure of KGK metering
valves ranges from 2MPa to 20MPa. Set
the lowest air pressure at which your
metering valve works properly.
② Material Outlet
Connect a metal pipe such as copper or steel between the
outlet (Rc1/4) of the metering valve and dispensing
equipment such as a nozzle. In this time, keep the pipe
as short as possible.
CAUTION: Avoid using a soft material like a nylon
* When connecting the outlet of your valve to multiple nozzles, install 686441 Restrictor respectively close to
each nozzle. Adjust the restrictors to make each of metered shots equal amount.
* When applying a metered shot at a constant length, attach 686442 Automatic Valve (sold separately) or
686437 Automatic Flow Gun (sold separately) to a material outlet.
tube for connection. Metered shots will
be variable in amount. In case that you
have to use a flexible tube or pipe,
attach an automatic valve to the pipe
(tube) end to obtain accurate shots
equal to a metal pipe.
