Use and Operation
Valves for actuators with memory (V0325): realized for use on cylinders with memory for outside drills reversible ploughs, it’s provided with a dual cross relief valve which provides protection against tear’s shocks when the plough exceeds the dead point.
Valves for actuators without memory (V0326): realised for use on cylinders without memory for outside drills reversible ploughs, it is provided with a dual cross relief valve and with a relief valve: this enables to reduce the thrust pressure (block side) in order not to damage the mechanical locks and the plough’s head.
Both systems are provided with a fixed compensated flow control valve which allows to keep a constant speed whether the plough works inside the drills or outside.
These valves are supplied with exchange pressure at 140 Bar, the relief valve is set at 90 Bar and the dual cross relief valve at 210 Bar. According to your requirements, pressure settings can be modified.
Materials and Features
Connect C1 and the dual cross relief valve to the cylinder from the stem side through the double holed screw ( supplied with the valves) and double banjos, connect C2 to the cylinder from the block’s side, P and T to the machine inlet.
