directional valve,  by-pass valve, indicator,  diffuser. It is simple in structure and easy

safety. The feature of this filter allows continuous operation even during replacing

element, which is clogged by contaminant. When 
the filter element  is clogged by contaminant that results in the pressure reaching to

0.35Mpa,   the indicator will  give signals. At  this time, turn the directional valve in

order  to make the other filter work then change the element.If the filter  can's be changed

in time that make the pressure reaches to 0.4Mpa, then the by-pass valve will  open to keep

the system safety.  The filter has check valve, so when it was installed at the side or in

the bottom of  the tank and
change element, it  won't let the oil flow out  of the tank.
The diffuser is installed under the filter bowl, which makes the medium flow stably into the

tank.
