HYDRAULIC LOCK VALVE: (Head Tilt Function)
An Electric Solenoid Operated Hydraulic Lock Valve (Figure 4) is incorporated in the Head Tilt
Function to prevent excessive (Head Lift Cylinder) leak down during storage or transportation.
The Solenoid which operates this valve is normally in the Locked position until Head Lowering
function is actuated at Joystick. When Joystick is actuated to lower Head an electric signal
is sent to solenoid to open Lock valve. When the function to raise the Head is activated there
is no electric signal from Joystick. The pressure against the valve when head is being raised
will force Valve open like a relief Valve allowing Oil to pass through it. If this valve will not open
it could stop head from lifting or dropping. The valve is plumbed into the Hydraulic Circuitry of
the Head Tilt Function and is located near the Control Valve.
