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 the valve when oil flows from cylinder to tank, from pump to cylinder, as well as the pressure drop from pump to tank by free flow in neutral position of the main spool.
