Cetop 5 / NG10 12vdc Solenoid Directional Valve - slow response AD5E.01.C.M.J52

Cetop 5 / NG10 12vdc Solenoid Directional Control Valve with spool movement speed control.

The ARON NG10 directional control valves are designed for subplate mounting with an interface in accordance with UNI ISO 4401 - 05 - 04 - 0 - 94 standard (ex CETOP R 35 H 4.2-4-05). The use of solenoids with wet armatures allows an extremely safe construction completely dispensing with the need for dynamic seal. The solenoid tube is screwed directly onto the valve casing whilst the coil is kept in position by a ring nut. Great care has been taken over the design and production of the ducts and the improvement of the spools allows relatively high flow rates to be accommodated for its size with minimal pressure drops ( Δ p). The operation of the directional valve is electrical. The centring is achieved by means of calibrated length springs which, once the impulse is over, immediately reposition the spool in the neutral position. The solenoids, constructed with a protection class of IP66 in accordance with BS 5490 standards, are available in direct current form and different voltage. The electrical controls are equipped with an emergency manual control inserted in the tube. The ADP.5.E.. valve has certain design features which allow it to “manage” a hydraulic power equal to Q = 120l/min with a P = 320 bar, maintaining a considerable safety margin. These features can be summarized as follows:

• Solenoid D19 with an optimum ratio between the power absorbed (42W) and the magnetic force
• Diameter of the spool 18 mm, with carefully designed geometry improved to compensate for the flow forces
• Compact graphite cast iron valve casing with high mechanical resistance
• Different springs, improved according to the features of the spool

The electrical supply connectors meet DIN 43650 ISO 4400 standards; connectors are also available with built in rectifiers or pilot lights.

The recommended fluids are hydraulic mineral based oils in accordance with DIN 51524 and it is recommended that filters should be fitted to ensure a maximum contamination level of class 10 in accordance with NAS 1638, β ₂₅ ≤ 75.

Valves type AD5.E... with spool movement speed control.
These ON-OFF type valves are used when a lower spool movement speed than usual for conventional solenoid valves is required to prevent impacts which could adversely affect the smooth running of the system. The system consists of reducing the transfer section for the fluid from one solenoid to the other by means of calibrated orifice.

• This version can only be used with a direct current (DC) and also in- volves a reduction in the limits of use so that we suggest to always test the valve in your application
• To order AD.5.J* version valves, specify the orifices code.
• The operation is linked to a minimum counter-pressure on the T line (1 bar min.)
• The switching time referred to the spool travel detected by a LVDT transducer can vary for the NG10 valve a minimum of 200 to a maximum of 400 ms depending on 5 fundamental variables:
  1. Diameter of the calibrated orifice
  2. Hydraulic power for clearance referring to flow and pressure values through the valve
  3. Spool type
  4. Oil viscosity and temperature
  5. Counter-pressure at T line
• Possible mounting: C / E / F / G / H
• 19 / 20 / 21 spools not planned for AD.5.E...J*
