Pressure Relief Valve

The pressure relief valve is fitted in the inlet section of the valve bank and protects the hydraulic

components from damage caused by loads in excess of 2500 psi (S

TAR

IGHT

™ and

EATHERWEIGHT

™) or 2750 psi (S

UPER

UTY

™). When pressure exceeds the setting of the relief

valve, the oil overcomes the adjustment spring and opens the relief valve allowing oil to return to the

tank.

Work Circuits

The circuits are listed from top to bottom in the same order as they appear in the valve bank assembly.

OTE

The following list is for the commercial front loader only.



Hopper Top Door Circuit:

The hopper top door circuit includes one double-acting hydraulic

cylinder and two flow restrictors.



Tailgate Circuit:

The tailgate circuit consists of two double-acting hydraulic cylinders, one

holding valve and two flow restrictors.



Arms Circuit:

The arms circuit consists of two double-acting cylinders and a deceleration valve

(a second deceleration valve can be installed on the circuit as an option).



Forks Circuit:

The forks circuit consist of two double-acting cylinders.



Pack/Return Circuit:

The pack circuit consists of two double-acting, 3-stage cylinders and a

pilot-operated check valve.
