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.

SPECIFICATIONS
GENERAL
• Double spool type valve with free flow in neutral position.• Hydraulic port sizes pump (P), tank (T) and cylinder (Cyl) BSP 1” .• Pneumatic port sizes tipping and lowering BSP 1/8”.• Pressure gauge point (Mp) BSP 1/8”• Operating air pressure 0…6 bar. (0…85 psi)• Max. working pressure by insert cartridge: 135, 150, 170, 190, 200, 220 or 250 bar.
(1930, 2145, 2430, 2720, 2860, 3145 or 3575 psi)• Shock absorbing valve, setting 270 bar. (3861 psi)• Max. pressure on T port 40 bar. (572 psi)• Max. flow 220 l/min (58 Usgpm) at visc. 32cSt. 40ºC (104ºF)• Fluid: Mineral oil according to DIN 51524/51525.• Allowed max. contamination level NAS 1638 class 11, or ISO 20/17.• Fluid temperature range –35…+80ºC. (-31…+177ºC)• Max. flow adjustment for lowering.
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.
