Handling of flow adjustment valve

When flow is adjusted with the flow adjustment valve, do not apply excessive force to rotate it.
This can damage the valve mechanism.

When fixing the valve of the flow adjustment valve, do not apply excessive force to rotate the fixing knurl.
This can damage the knurl and valve mechanism.

After adjusting the flow, be sure to check that there is no water leakage.
After adjusting the flow, water leakage may occur due to the stability of the seal in the valve. If water leakage occurs,
open and close the valve several times to readjust it, and check that there is no water leakage.

The flow rate adjustment valve of this product is not suitable for applications which require constant
adjustment of flow rate.
Fluid leakage may be generated when the internal seal reaches the end of its life due to wearing.
Therefore, take measures to protect peripheral equipment, ensure maintenance space and pay
attention to the piping design.

The flow rate adjustment valve of this product is not suitable for applications which require reducing the
flow rate to zero completely. When it is necessary to set the flow rate to zero, select the product with a
stop valve.

Do not lift it by gripping the knob of the flow adjustment valve.
Hold the main piping plate when handling it.

If fluids with high temperature are flowed, the flow adjustment valve itself will also become hot, which
leads to a burn. Therefore, use the flow adjustment valve with special care.

How to handle the stop valve

When the flow rate is adjusted to zero using the top valve, do not rotate the valve with an excessive
force.
The valve construction might be broken.
The maximum rotation angle of the stop valve is 90°.

When the stop valve handle is held, do not tighten the screw with an excessive.
The handle and valve construction might be broken.

Screws are prepared by the user.


The stop valve of the product is not suitable for adjusting the flow rate. When the flow rate needs to be
adjusted, please select the product with flow adjustment valve.

Do not hold the handle of the stop valve when it is carrying around.
Hold the main piping plate when handling it.

If fluids with high temperature are applied, the stop valve itself will also become hot, which may cause
burns. Take special care.
