3.1. GENERAL DESCRIPTION
This valve is composed of the body,plunger,piston,springs,and plug.It serves to absorb shocks
which are given when the PTO clutch engages.
3.2. OPERATIONS
1) When the clutch cylinder is achieved:
When the PTO clutch valve is turned on,the cylinder is activated.Consequently the pressure in
circuit does not leave the seat of body(4) because the preset force by spring(8) and spring(9) is
larger.Therefore there is no flow of fluid from port B to port T,which means all the fluid from the
PTO clutch leads to the clutch cylinder.
