รายละเอียด Directional spool valves, pilot operated, with electro-hydraulic actuation รุ่น H-WEH

• Size 10, 16, 25 (H-WH22), 25 (H-WH25), 32
• Component series 4X, 7X, 6X
• Maximum operating pressure 350 bar
• Maximum flow 1100 l/min

Features

• Types of actuation (internal or external pilot control): Electro-hydraulic (type WEH)
• For subplate mounting
• Porting pattern according to ISO 4401 and NFPA T3.5.1 R2
• 4/3-, 4/2- or 3/2-way version
• Spring or pressure centering, spring end position or hydraulic end position
• Wet-pin DC or AC solenoids, optional
• Electrical connection as individual or central connection
• Optional versions:
  • Manual override
  • Switching time adjustment
  • Preload valve in channel P of the main valve
  • Stroke setting and/or spool position monitoring

Type code

1. 2 spool positions (hydraulic end position): only symbols C, D, K, Z, Y
   • 3 switching positions (hydraulically centered): only NG16, NG25 ("4W.H 25") and NG32
2. Only with electro-hydraulic actuation (type WEH)
3. Pilot oil supply X or return Y external:
   • The maximum admissible operating parameters of the pilot control valve must be observed (see data sheet 23178)!
   • Minimum pilot pressure: please see technical data!
   • Maximum pilot pressure: please see technical data!
4. Pilot oil supply internal (version "ET" and "E"):
   • Minimum pilot pressure: please see technical data!
   • Maximum pilot pressure: please see technical data!

With a higher pilot pressure, use of a pressure reducing valve "D3" is required (if it is not used pilot pressure = operating pressure at the port!).

• In order to prevent inadmissibly high pressure peaks, a "B10" throttle insert has to be provided in port P of the pilot control valve (see Pilot oil supply).
• In connection with version "H", the pressure reducing valve "D3" is also required.
5. Only in connection with the "B10" throttle insert
6. Mating connectors, separate order, see data sheet 23178
