Hydraulic override of pressure position mark
When you have a HA control, the beginning of a control may be done by putting a pilot pressure to port x. For every bar of pilot pressure , control start is lessened by 17 bars for 28-200 sizes and 8 bar s for 250 to 1000.
The override valve is made to position the highest displacement psi and pilot pressure of 1450 psi is allowed.
Electrical Override of Pressure Position Mark
You can put the control start position to be at 1160 & 4350 psi. If you were to order this part, you can tell them where to put the values at. The solenoid and electrical signal is the factor for overriding your control. When it does override, the variable displacement motor turns to the highest turn angle.
When you have a travel direction valve makes sure the desired pressure outlet of the hydraulic motors controls the turn angle when or if the high pressure side adapts itself (while it is going down). This will not let any turning of the variable displacement motor go to a larger displacement.
With the guidance of the rotation, the travel valve can be determined by way of the compression spring or solenoid.
