–
A’ coil is energized, and ‘B’ coil is powered off, the spool moves to the
direction of the ‘A’ coil.
–
B’ coil is energized, and ‘A’ coil is powered off, the spool moves in the
direction of the ‘B’ coil.
–
‘A’ and ‘B’ coils are powered off at the same time, the solenoid valve
spools back to the middle position, forming a closed loop, that is, the
two chambers of the cylinder are completely closed, resulting in no
movement.
The valve has four channels: P, T, A and B.
‘P’ is for oil In, ‘T’ is for oil Out, ‘A’ and ‘B’ is for output.
When the electromagnet is not energized, the reversing valve is in the
middle position. The PTAB is connected to each other in the middle of ‘H’
type. In the middle position of ‘Y’, TAB is connected to each other, and P
is disconnected from other routes. Type 0 directional valve in the PTAB
access is blocked. In the middle position of ‘M’ type, PT communicates
with each other, ‘A’ does not communicate with other, and ‘B’ does not
communicate with other.
“H” type: all oil ports are connected, the system is unloaded, and the
cylinder is floating. Hydraulic cylinder is connected to oil tank in two
chambers, from static stop to start impact. When braking, the oil port is
interconnecting, and the braking is more stable than the “O” type, but the
reversing position changes greatly.
“Y” type: the oil pump does not unload, the hydraulic cylinder is
connected to the oil tank in two chambers, there is impact from rest to
start, and the braking performance is between “O” type and “H” type.
“O” type: all oil ports are closed and the system does not unload.
Hydraulic cylinder filled with oil, smooth from rest to start. When braking
motion inertia caused by hydraulic impact. High accuracy of reversing
position.
“M” type: oil pump unloading, from rest to start smoothly. The braking
performance is the same as the “O” type.
The hydraulic system should be purged at this time. Listed below are the
directions on how to purge the hydraulic system.
How to purge the hydraulic system.
1. Start the engine.
2. Power the winch to draw out about 5 feet of cable.
3. Shut down the engine.
4. Check the fluid level and fill as needed.
5. Repeat steps 1 through 4 as necessary.
6. Start the engine.
7. Move the cable into the desired position.
8. Turn the wheels on the vehicle from the right lock to the left lock
positions five times to help bleed the hydraulic system.
9. If the hand control unit is working backwards, simple exchange the
brown and the white wire connections within the valve.
Test the winch for proper operation. Refer to the Operation section.
