particles between seat and plug

Remove foreign particles.

Contact SAMSON's After-sales Service when

parts are damaged.

Control loop hunts

Regulator or K

coefficient too

large

Check the sizing.

Change K

coefficient, if necessary or

install a different sized regulator.

Contact SAMSON's After-sales Service.

Loud noises

High flow velocity, cavitation

Check the sizing.

Install larger regulator, if necessary.
