DESCRIPTION
The AMCA proportional directional control valves are pressure
compensated and archieve an ideal control of force, speed,
acceleration and deceleration, independent of the load and
increased demands.
The pressure compensator could be a pressure relief valve
(MUV) or a pressure reducing valve (MDM), together with the
throttling function of one or more directional control valve spools.
The shape of the proportional directional control valve spool
differs from the conventional one.
The result is a progressive flow curve. To make optimal use of
the maximum stroke of the spool, the flow angles of the A and/or
B port can be defined for different flows. For a constant flow, the
pressuredrop over the orifice of the spool remains constant,
independent of the load pressure.
2-types of joystick control:
FEATURES
The load independent output flow is proportional to the input
signal (control pressure).
The pump pressure always corresponds to the user
pressure, +3,6,8 or 12 bar (43, 86, 114 or 172 psi) Äp
compensator.
The built-in pump-unloading valve results in:
- very low power turned into heat;
- minimum loading of the prime mover.
User speed is precisely controlled under all load conditions.
Progressive regulating curve; no pressure peaks when
switching; sensitive control even for alternating pressures.
Constant working speed of differential cylinders at the
different regulating flow to the valve by grinding angle.
Constant recirculation pressure independent of the number
of units.
Any limiting of flow for every user port.
Proportional directional control valves also available as:
- Manual proportional series MHV and
- Electrical proportional series MEV.
Any combination of these control options is possible.
The sandwich and subplate system allows a construction up
to 8 control valves.
Electrical pressure cut off at port A, B or A and B, available
on request.
