1. Warning Report
1. Warning Report
Before installation and using our dispensing valve BV-300, please be fully a are of this user manual.
■Fluid Leakage Hazard
-If the fluid splashes up to your eyes or skin, it can also cause a serious injury.
-Handle with extreme care not to be in contact with liquid in case of nozzle exchange or cleaning.
- ake sure that pressure must be released before the nozzle is removed when you exchange a nozzle.
■Valve Overuse Hazard
-If a valve is damaged due to excessive pressure, unauthorized alteration of parts, and overuse, it may cause a danger
by exploding or leaking (explosion or leakage may occur).
-Do not make any kind of unauthorized alterations.
We are not responsible for any repairs, after-sales service caused by them.
-This valve operates under max material delivery air pressure 4kgf/cm².
Do not exceed this operation pressure.
■Others
High pressure material can be leaked if a hose is damaged or worn.
Check a hose for any worn-downs, damages, or swollen before use.
Please change a hose immediately if any malfunction is found.
Prevent leakage from loosened joints by tightening before use.

3. Install and Operating
3. Install and Operating
1.Installation
1) Connecting a Air-Pressure Line
- Straightly insert the tube into the air fitting until it gets installed inside.
-Pull the tube gently in order to make sure that it is safe.
2) Connecting Fluid Line
- The inlet of Fluid line fits in PT1/8” line.
3) Caution
①When you cut the tube, make the severed side a right angled out and the use of a tube-cutter is
recommended.
②Install the fluid line in oblique with the air line in order to minimize the intervention.
2. Operating
1) How to Use
①Open the fluid line and air line of the valve.
②Keep dispensing until the consistent drippings are made from the nozzle and stop dispensing.
2) Control of the deposit volume
Refer to the following directions so as to control the flow of liquid and the size of bubbles.
①Adjust the pressure of fluid inlet of the valve.
②Use the nozzles with different sizes in order to control the size of bubbles and to make fluid with
different viscosity.
③For more precise controlling, adjust the stopper handle(No.12) of the valve. When it’s done, lock the
nut No.11.

4. Maintenance and Cleaning
4. Maintenance and Cleaning
1. Maintenance
1) Things to Check while Operating
①ake sure that air supply is in good condition.
②Check other appliances that are properly powered.
③Be sure the end of nozzle is not clogged with fluid.
2) How to Disassemble
The user’s arbitrary disassembly is not recommended.
First follow the steps for air-pressure release then separate the nozzle from the air tube completely.
3) How to Assemble
The user’s arbitrary disassembly is not recommended.
First follow the steps for air-pressure release then separate the nozzle from the air tube completely.
4) Replacement Span for Parts
①The List of Parts that requires replacement.
- O-Ring set(P1,P2,P3)
- Packing Seal(7)
- Valve Seat(17)
3) How to Keep after Use
① To avoid a nozzle’s air contact, put an end-cap on the nozzle or keep a nozzle in the grease.
② Follow ① Cleaning of 4.Maintenance 2)Cleaning while cleaning.
4) Caution
Do not exceed the liquid pressure of 40kgf/cm and the air pressure of 4kgf/cm
4kgf/cm4kgf/cm
4kgf/cm so as to reduce the risk
of over-pressure, which can cause serious damages and disorder

5. Troubleshooting
5. Troubleshooting
1. No Fluid Flo
1) Check to see if SHAFT is in proper operation.
2) ake sure that fluid is not hardened.
3) Check to see if fluid needs to be refilled.
4) Be sure that the controller as well as other appliances are properly powered.
5) Check the air supply.
6) ake sure no shift is made in air line.
2. Fluid Leakage
1) If fluid leaks from the nozzle, remove the needle adapter No. 14 and clean up dirt in Seat Cap(Ni,4-1)
or replace the Valve Seat 17.
2) If fluid leakage occurs in the Packing Pusher Hole No 5, replace the Teflon Packing in it.
3) If leakage is due to the Shaft worn-out, replace No.9.

2. Cleaning
1) How to Clean
① Stop providing liquid and disassemble.
② Connect the cleaning line to fluid supply line and add pressure.
③ Follow the operation guide of 3-2 and dispense cleaning liquid instead of fluid.
2) Caution
To minimize possible damage on skin or eyes by fluid, please strictly follow the procedure for
air-release before part-replacement or valve-cleaning.
3) How to Release Air Pressure
① Cut off the supply of air and fluid into the dispensing valve.
② With the valve facing In a round container, open the valve and dispense liquid to remove
the pressure.
