2. Product Description
KGK metering valves are able to apply metered shots of media such as greases and adhesives. By replacing a built-in
metering cylinder, KGK metering valves cover metered shot volumes between 0.5mL to 50mL.
CAUTION
- When leaving the product unused for a long time (more than a week) or shutting it down;
- remove material inside completely and wash the product and
- release material supply pressure.
CAUTION
- In grease metering valves, NBR and urethane rubber are used in seal parts. Do not try to handle any
material incompatible with these parts. If need arises, use adhesive metering valves which use seal parts
made with fluorine resin.
- Release residual pressure inside the valve BEFORE maintenance, inspection, and repair.

Material delivered to the supply channel lifts up the valve
with its pressure and presses it against the seat on the
discharge side. While the valve is blocking material flow to
the discharge port, Chamber A (metering chamber) becomes
filled with material.
At the same time, material, under pressure from a supply
pump, is constantly being delivered to Chamber B (pressing
chamber) at the back of the metering piston through a bypass
groove around the valve.
At this time, when the same pressure is applied over both
Chamber A and B, the force acting on Chamber A is stronger
due to a difference of pressure receiving area.
Thus, the metering piston is pushed to Chamber B and
comes to a stop against the head of adjustment screw.
When the air piston is pushed down by supplied air, the
material inlet is closed and the material outlet opens. Then,
material pressure in Chamber A decreases with material flow
from the chamber. At the same time, regardless of valve
condition, material, under pressure from a supply pump, is
constantly supplied to Chamber B through the bypass
groove. Accordingly, the metering piston starts moving
forward and material in the metering chamber is discharged.
The metering piston pushes out all material inside the
metering chamber and comes to a stop against the end wall.
Discharge is now complete. Even when valve is open toward
the discharge side, material other than a metered shot will
not flow out.
After supplied air is discharged, the valve is lifted up by
material pressure and again pushed against the seat on the
discharge side to close the material outlet. Material flows into
the metering chamber as pushing the piston back. Residual
material in Chamber B flows back through the bypass groove
to Chamber A, being mixed together with newly delivered
material.

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
①Material 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.
②Material 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
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.
* 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.

③Air Inlet
Connect an appropriate air valve such as 3 port solenoid valve or mechanical valve.
CAUTION: Air should be supplied through an air filter, lubricator, and air regulator. Set the air pressure
between 0.4MPa to 0.5MPa.
WARNING: Do not set the air pressure over 0.7MPa.
4-4 Precaution for initial use
When you use the metering valve for the first time including the first use after repair, be sure to completely
remove trapped air from a material supply pump, hose, pipe, and metering valve.
Disconnect a pipe attached on the material outlet and run the metering valve to remove trapped air. Repeat
this procedure until all air is removed completely. Confirm that the valve is securely closed BEFORE
reconnecting a pipe to the outlet.
PRECAUTION FOR USE
- Be sure to shut off the air supply to a supply pump and set the material pressure (primary pressure) to
zero. Leaving a metering valve under pressure will be a cause of material leak or some other problem.
- Once a metered shot is dispensed, be sure to put the valve back to the standby condition.
- Avoid inclusion of air in material as much as possible.
Trapped air in material will be compressed through a pump, pipe, hose, and metering valve and expand
when material is dispensed. As a result, the metering valve will have difficulty stopping discharge and
thus it may seem to be leaking. Also, each shot will be variable in amount.
Furthermore, material will gush out of the outlet and splatter around.
Be sure to release air completely when using the product for the first time or after replacing a metering
cylinder.
- Do not use material which contains dirt and dust. Seal parts will be damaged, causing a material leak.
- In such problems that material continuously flows out from the outlet or a shot is variable in amount, it is
necessary to figure out whether a defect is caused by malfunction of the valve or some other equipment.
Carry out an operation test on your valve independently and investigate the condition of the material
outlet.
- Due to long term use, material which couldn’t be stripped off by a seal builds up little by little. This is not
always abrasion of a seal part. It is important to wipe off seal parts after use or periodically to extend the
life of these parts.

6. Disassembly and Assembly
PRECAUTION FOR USE
- Please contact the store you purchased the product or our business office if a metering error has
happened soon even though it didn’t occur at the beginning of use.
- When handling silicone grease, be sure to select a designated valve for silicone grease. If a grease or
adhesive metering valve is used, seizure of a valve and sleeve will occur, resulting in malfunction of a
metering valve.
CAUTION
If material flows out continuously even after a metered shot has been dispensed, it may be caused by
conditions of inlet or outlet lines or a procedure taken to restart operation after repair. Please follow the
following recovery procedures.
- When using a metering valve for the first time including after repair, run the valve without connecting
dispensing equipment, coupling, hose, or any other accessories to a material outlet. Keep running the
valve until all trapped air inside a material supply pump, hose, pipe, and metering valve is expelled
completely. Make sure that the valve is closed before making connection to the outlet.
- When material continuously flows out from dispensing equipment or an outlet of a secondary pipe, the
outlet of the metering valve doesn’t generally have a defect. In most of these cases, it is caused when a
pipe line is too long or short or when material of a pipe is flexible. To solve this problem, repeat
“Discharge” and “Standby” until continuous flow stops.
CAUTION
- Release residual pressure completely BEFORE disassembling metering valves.
- Wash the parts with wash oil and apply a thin layer of lithium grease BEFORE reassembling.
Be extremely careful not to let dust and dirt attach to any of the parts.
