Function

NVD2 is a highly innovative directional control valve, which paves the way into the world of proportional valves. NVD2 technology (patented) impressively links constructive simpli-city and high functional performance; a simple and compact design, typical of the more traditional open-centre directional control valves.

It is associated with an extremely precise control, indepen-dent from the load conditions and simultaneous movements. The flow sensing principle is efficient when electrically ope-rated. It reaches its maximum potential when used in combi-nation with radio remote control or electronic control devices.

NVD2/4, example of customized configuration

The flow sensing principle is based on the equilibrium bet-ween the metered oil flow and the electro-proportional actu-ation forces, so this direct feedback makes the flow control independent from loads and simultaneous movements.

Directional control valve NVD2 is availiable in its standard version for fixed displacement pumps, on request it can be also configured for variable displacement pumps.

With fixed displacement pumps, the open centre achitecture allows a very low system pressurization at stand-by condition.

The ordering configuration is generated by assembling a string of codes that allow to define the valve assembly.

This string is made by defining the inlet section first, then the work sections and at the end the outlet section and fixing devices.

See below an example of NVD2 model code and on the fol-lowing pages the options for each block of strings.

1) The work section string configuration must be repeated as many times as the number of work sections composing the control valve.

The hydraulic layout of NVD2 flow sen-sing control valves is similar to any open-centre directional control valve.

The technological feature that makes the NVD2 operational concept similar to a load sensing directional control valve is the fact that, being electrically operated, it controls the flow indepen-dently from load conditions and the si-multaneous movements.

Manual actuator device is provided as emergency feature in case of malfunc-tion of the proportional electro-hydraulic control device: in case of malfunction, the NVD2 directional control valve acts as a normal open-centre one.

NVD2 inlet module has a P power supply connection and a T connection so that the connection to the reservoir can be easily chosen either at the DCV inlet or outlet. The module is equipped with a general pressure relief valve and it integra-tes the pressure reducing valve (18 bar) for power supply to the proportional electro-hydraulic controls. The pressure re-

ducing valve is equipped with a 30 µm filter for the protection of the proportional electro-hydraulic valves. At user’s choice, the input module can host a pre-loading valve. This valve is used to keep the standby pressure at a suitable level in order to have a quick reaction by the proportional electro-hydraulic controls.

NVD2 work section consists of a spool and related flow con-trol valves, proportional electro-hydraulic valves, lever kit and port pressure relief valves. The proportional electro-hydraulic valves are placed in the lower part of the section and the flow control valves can be reached by disassembling them.

In order to guarantee best functionality, the parts must be duly chosen according to the system features. The spool must be proportional to the pump capacity, while the flow control valve must be proportional to the desired flow capacity on A and B ports, which may be different along the same section (i.e. A12/ B24).

Proportional electro-hydraulic valves NVD2 must be driven by PWM signal. By adjusting the maximum current value, it is possibile to set the maximum flow supplied from each port.

In order to reduce control hysteresis as much as possible and guarantee the most reactive operation, it is recommended to set the PWM carrier frequency at 60 Hz and anyhow not ex-ceed 90 Hz.

The NVD2 outlet section allow to manage a second return port and the possibility to install an electric dump valve that ensures, in the absence of power supply, the entire distribu-tor can not be operated.

Besides, the outlet section can be configured for carry-over connection feature, that allows to install NVD2 in serial with other hydraulic devices.

NVS3/3, Example of customized configuration

Function

NVS3 is a range of compact electric directional control valves (DCV) designed for mobile applications where weight and di-mensions are key factors.Its architecture is based on the combination of SAE 10 DCV cartridges screwed into modular aluminum manifolds.Thanks to its modular design it is possible to assemble up to 8 sections of 4 way, 3 position on-off solenoid valves ar-ranged in parallel and feed by on-off or proportional electro-hydraulic inlet elements.The inlet elements can be configured with many options as: different type of pressure relief valves, dump valves, load in-dependent proportional flow control, carryover by-pass line.On request, it can be easily customized to integrate specific features.

NVS3/3, Example of customized configuration

Function

NVS3-LS is a compact load sensing, proportional electro-hydraulic actuated directional control valve (DCV); designed to control a maximum inlet flow of 30 L/min. Its architecture is based on the combination of SAE 10 DCV cartridges scre-wed into aluminum bodies. Thanks to its modular design it is possible to assemble up to 8 sections of 4 way, 3 position proportional solenoid valves arranged in parallel.The inlet elements can be configured with many options as: different type of pressure relief valves, dump valves, carry-over by-pass line.On request, it can be easily customized to integrate specific features. NVS3 is designed for basic applications where the flow con-trol isn´t required under simultaneous movement. Typical applications for NVS3 are self-propelled access platforms or small cranes.

Notes:To be noticed that the load sensing internal line is direct connected to work sections A/B ports. The control spools are open center types in order to prevent the pump pres-surization due by load induced pressures with SAE-10 4way/3pos cartridges not actuated.

As consequence of the above feature the carrying cylinders must be provided of load holding valves (Counterbalance or Pilot Operated Check valves, see NEM valve catalogues vol.1 and 2).

The ordering configuration is generated by assembling a string of codes that allow to define the valve assembly.This string is made by defining the inlet section first, then the single working sections.See in the next page an example and in the following pages the options for each block of strings.
