EVC Operating Control Unit
The EVC control unit is constructed of modules and consists of;
•
Pressure Relief Valve
•
Pressure Regulator
•
Pressure Gauge
•
Flowmeter (fitted on electronic control)
•
Section distribution valves
•
Constant Pressure Equalisation valves
Pressure Relief valve
The pressure relief valve mounted to the end of the fluid
distribution manifold enables control of the maximum liquid system pressure.
EVC Pressure Regulation Valve
The pressure regulator controls the system pressure allowing excess fluid to bypass back to the main tank.
Pressure Gauge
The pressure gauge gives a visual indication of the system pressure and can easily be viewed from the tractor cab.
Section Distribution Valves
The distribution valves offer independent control of fluid flow to the boom sections enabling operation of either
left wing, right wing for versatile application of chemical product.
Constant Pressure Equalisation Valves
Mounted underneath the distribution valves is an adjuster that controls the constant pressure for the distribution
valves, this helps to maintain a constant system pressure when the distribution valves are opened or closed.
