FEATURES• 3/3-way pneumatic-hydraulic valve with built-in

relief and lowering feature.• Resistance-free lifting of loads.• Safe holding of loads at any point.• Fast lowering of empty body and light loads.• Safe lowering of heavy loads at slower speeds.

(Proportional control)• Easy-to-fit to new and existing installations.• AMCA tipper valves also available for manual

and cable control.• A surge damping valve to prevent peak

pressures in the system.• With lowering adjuster.

The diagram shows the internal resistance in thevalve when oil flows from cylinder to tank, frompump to cylinder, as well as the pressure drop frompump to tank by free flow in neutral position of themain spool.

Available options:• Thread SAE and NPT.• Check valve on P port.

MOUNTING POSSIBILITIES

• Standard mounting to the oil tank, with mounting block welded to the oil tank, making aseparate return line unnecessary.

• As a “remote control system” mounted in the chassis. A separate mounting kit with plateis available. Note: In this case a return line between valve and oil tank is necessary.
