6.6 Flow regulator valve 

The flow regulator valve, located in the lift cylinder circuit to limiting the descending 

speed of loaded forks, has the construction as shown in Fig6.7. When the lift spool valve 

is placed in the 

“lift” position, the oil from the control valve flows through the oil chambers 

A  and  B,  oil  holes  C,  D,  E  and  F,  and  the  chamber  G  to  the  lift  cylinder  without  any 

regulation. When the lift spool valve is placed in the 

“down” position, the oil flows in the 

reverse  position.  When  the  oil  passes  the  throttle  plate(5)  and  a  pressure  difference 

overcomes the force of the spring(2) and moves the valve core (7) right, thus the oil flow 

being  decreased  by  narrowing  of  the  hole  D  and  C,  and  reduces  the  oil  flow  passing 

through the throttle plate(5). 

The flow regulator valve controls the goods descending speed and serves as a safety 

device, prevent the danger for suddenly descending if the rubber hose ruptures between 

the control valve and the lift cylinder.
