Special attention: please experience technicians or the company's sales staff, not to
adjust.
If the pressure adjusting screw is rotated clockwise, the use pressure will be increased,
and vice versa.
5.4 Safety valve adjustment:
Special note: the service pressure of the compressor shall not be higher than the rated
working pressure of the compressor. If the adjustment is needed, it must be made by
experienced technicians or the company's business staff, not by themselves.
The relief pressure of the relief valve is generally set higher than the exhaust pressure
of 0.1mpa, so there is no need to adjust it by itself. If it is necessary to adjust the
discharge pressure of the safety valve for other reasons, loosen the lock nut of the
safety valve and adjust the screw again. If the valve is rotated clockwise, the discharge
pressure will be increased; if the valve is rotated counterclockwise, the pressure will be
set down; after setting the discharge pressure, tighten the lock nut.
