Purpose
This product is a set of electric-mechanical transformation equipment. In the range of the rated stroke and rated current, the input force is proportional to the input signal. Together with proportional control amplifier, it can be realized accurate control to electric-hydraulic valve spool. It has characteristic of long stroke, high repeat accuracy, high output force, etc. as compon ent of directly proportional spillover valve, proportional flow control Valve, and proportional throttle, combination valve(PQ valve).

Operating Notice
● Installation Position
The vent hole must be installed on above.
● Exhaust
In order to realize stabilization control,please make the air out of the solenoid thoroughly,and full of oil.
When exhausting,please open the bolt slowly and slowly.Be careful the spilling!
● Adjust The Bolt By Hand
If there is no current at the beginning adjustment or because of electrical accident,you can turn the bolt by hand;set the pressure or flux of the valve temporarily,please make sure the handle bolt return to the position at normal operating.
