3 - FLOW LIMITATION

When the solenoid valve is fed by an accumulator or by high delivery pumps it is necessary to limit the flow to the working limits by means of

orifices. The orifice must be located on the accumulator side always.

WARNING! During the transition from one to the other end position all ports are interconnected. This means that during the

switching the oil will be flowing from the accumulator to the tank through the valve, until the swithing is completed.

That is why the maximum flow should be limited up to 12 l/min by placing orifices.

5 - ELECTRICAL FEATURES

5.1 - Solenoids

These are essentially made up of two parts: tube and coil.

The tube is threaded onto the valve body and includes the armature

that moves immersed in oil, without wear. The inner part, in contact

with the oil in the return line, ensures heat dissipation. The coil is

fastened to the tube by a threaded nut, and can be turned 360° on

its axis, compatible with space available.

The interchangeability of coils of different voltages is allowed within

the same type of supply current: alternating or direct (DC / RAC).

NOTE: The protection degree is guaranteed only with connector

correctly mated and installed.

5.2 - Current and power consumption

The table shows the consumption values for the

different coil type.

It is necessary to always use “D” type connectors (with

rectifier incorporated) and RAC coils for alternating

current supply.

Rectified current supply takes place by using a bridge

rectifier bridge, externally or fitted within the “D” type

connectors, between the alternating current source

(24V or 110V, /50 or /60 Hz) and the coil.

5.3 - Switching times

The values indicated refer to a flow rate of Q = 10 l/min, p = 210 bar

working with mineral oil at a temperature of 50°C, a viscosity of

36 cSt and supply voltage equal to 90% of the nominal voltage.

5.4 - Electric connectors

The solenoid valves are never supplied with connector.

Connectors must be ordered separately. See catalogue 49 000.

4 - HYDRAULIC FLUIDS

Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals. For fluids HFDR type

(phosphate esters) use FPM seals (code V). For the use of other kinds of fluid such as HFA, HFB, HFC, please consult our technical

department. Using fluids at temperatures higher than 80 °C causes a faster degradation of the fluid and of the seals characteristics.

The fluid must be preserved in its physical and chemical characteristics.
