Parts list


The control valve is one of the important parts that regulates oil f ow and controls hydraulic device.
O-rings seal the inside of the control valves. Use of appropriate O-rings that are suitable is
essential for proper maintenance of the overall machine performance. Toparts Select Parts O-ring Kit is
a package of the uniquely-developed O-rings which are replaced during overhauling control valves.
Roles of O-ring:
1 Preventing oil leak
The O-ring prevents oil leakage to the outside by press-f tting it to a control valve. Oil leakage
through a deteriorated O-ring may cause various troubles.

2 Preventing impurity intrusion
The O-ring prevents the intrusion of dust and moisture from the outside. Deteriorated O-ring and
intrusion of impurities may adversely affect other hydraulic devices including pumps, cylinders,
and motors by causing scoring, abnormal wear and other problems.
When oil leakage is detected in the control valve, early replacement of the O-ring is
recommended. Be certain to use O-ring Kit made of Toparts to maintain high machine
performance when O-ring is replaced.
