How to adjust the flow rate (when a flow adjustment valve is mounted) 

(1) Rotate the knob of the valve to adjust the flow rate to the target value. 
(2) Be sure to confirm that there is no fluid leakage generated after adjustment. 

(When fluid leakage is generated, open and close the valve several times for re-adjustment, and confirm 
that there is no fluid leakage.) 

(3) Tighten the lock ring to fix the valve as necessary. 
 

 

 
The flow adjustment valve is not designed for applications that require daily and repetitive adjustment. 
If the valve is adjusted frequently, fluid may leak due to wear of the internal seal.
