mv99
The proportional valve MV99 has specifically been studied to equip lifting machinery; the Load Sensing system and the
proportional electrohydraulic actuation allows for sensitive and accurate movement control.
Besides the inlet compensated version, now the fully compensated system is available: this resolves the difficulty of
simultaneous movements, even with different loads on the ports.
Applications
The valve is available with manual, hydraulic remote, pneumatic, electrohydraulic and electropneumatic controls.
Numerous configurations and solutions are possible.
Working sections have auxiliary valves and a broad range of interchangeable spools.
Larger sections are available to manage higher flows on tank line (Garbage compactors).
Suitable for applications including compactors, hook and skip loaders, wheel loaders and Refuse trucks.

inlet section
The inlet module includes the valve feed port Pand tank port T in addition to an outlet for LS signal. It can be variously
equipped with a 12 or 24 VDC electric operated dump valve, a main pressure relief valve, a pressure reducing valve
to feed the proportional electro-hydraulic control (equipped with a 30 mm filter) and a pressure relief valve. The open
center version for combination with fixed displacement pumps or the closed center version for variable displacement
pumps are both available. In the first circumstance, the spool functions as a general pressure compensator for the
Load Sensing system, whereas in the closed center version, it acts as a main stage for the main pressure relief valve.

The inlet section with KV configuration enables control valveusage with fixed displacement pumps. When fully equip-

device. Load Sensing flow rate control is achieved by the pressure compensator (4), which keeps a pressure drop
constant through the spool control notches by comparing the LS signal and feed pressure. In its standard version,
the main relief valve (5) acts on the LS signal. The pressure reducing valve (2), equipped with a 30 m filter and a
relief valve (3), feeds the proportional electro-hydraulic section controls.

valve (1) acts on full flow rate and serves as a safety device. In this case, the main relief valve (5) acts on a piloting

(2) ensures thatthe relative 30 m filter and the relief valve feed the sections proportional electro-hydraulic controls.

Spool flow
Flow rates delivered to the A, B ports and the return control characteristics of the spools are identified by a four letter
abbreviation as explained below:
w001C - A D F F
Spools are defined as standard when delivery and return flow rates are the same for each single port (ex. AADD, AAFF,
AAII).
The correct definition of delivered flow rates can be established via the following table where different notch types are
indicated. Following table shows possible flows for ports A and B: flows are different depending on the type of section
(compensated or not compensated): data are valid considering 100 l/min inlet flow and fixed pump configuration.
For complete simmetric spools (ex. AAAA, BBBB, CCCC), following flow rates are also available:
On compensated sections flow rates can be additionally increased about 15% by means of special compensator kit
RC4-RC5 (see page 27).

Special spools return action with hall effect Linear Position Sensor HLPS2
HLPS is a Hall effect sensor based device used in conjunction with spool position transdu-
cer kits available for MV99. HLPS is based on a state of the art programmable Hall effect sen-
sor device; after the final assembly of the valve a computer assisted calibration procedure is
performed that compensates for mechanical inaccuracies and uncertainties allowing to attain
high accuracy and linearity in spool position detection. Spool position is output as an ana-
log voltage signal in the 0.5 - 4.5V range. The unit works in 12V and 24V environments and
is protected against load-dump and other major electrical faults. Fault signalling is carried
out through the output signal. HLPS with the companion mechanical kit is therefore applicable in spool loopback
control applications and whenever determining spool position reliably is, as in safety functions, a major concern.

Not compensated section
A spool with ample flow ranges, differentiated on ports A and B if required, is used for each work section. Spool actuation
can be manual, hydraulic or proportional electro-hydraulic. The selector valve, which appears on all sections, selects
the highest LS signal and transmits it to the inlet module in the event of simultaneous section operation. The A and B
ports can also both be equipped with an auxiliary valve which can be of antishock, anticavitation or combined type, ac-
cording to requirements. When using not compensated sections, the Load Sensing principle (flow rate control is entirely
free from load variations) is guaranteed for each work section only when operated individually. If two or more sections
are operated simultaneously, only the one with the highest load will keep its flow rate constant against load changes.

The technical specifications of each non compensated section can be directly transferred to compensated ones. A local
pressure compensator spool is also provided. In addition to guaranteeing constant flow rate against load changes as in
the previous case, compensated sections also ensure this function during contemporary operation of two or more spools.
This solution exploits this highly developed Load Sensing system and frees each function from external disturbances.

The intermediate inlet section for the MV99 control valve allows inlet flow rate up to 200 l/min from a Load Sensing
variable displacement pump. This intermediate section has been designed to assemble two independent flow control
units, fed from a single, high flow rate pump. The symmetrical pressure drop control allows the regulated flow-rates
to be accurately distributed. Among the possible applications are travel systems for drills, excavators and medium- to
large-sized agricultural machinery.

Guidelines
- Mount the control valve securely to a flat surface (recommended 3 point fixing); at the time do not use a hammer
to positioning by hitting.
- When handling the control valve, be careful not hold the pilot cover or return spring cap of the spool or accessory
valves such as main relief valves and anti-shock relief valves.
- Clean piping materials sufficiently before use.
- Make sure to prevent the port openings from being entered with dust or foreign matters.
- Tighten the port connectors surely with the recommended fastening torques.
- Do not direct the jet of a pressure washing unit directly to the valve.
