Screw-in cartridge 3/4 directional valve SA4/H3

Two solenoids, one control system and an outstanding performance: The SD2E-A4/H3 screw-in directional control valve can be installed in any chamber with a ¾ UNF (SAE 08) internal thread, making it universally suitable.

4/3-way screw-in valve for ¾-16 UNF (SAE 08) internal thread

The screw-in valve clearly stands out on the market, thanks to its performance data: it can reach a flow up to 30 l/min, which is about twice as much as similar valves on the market. The 4/3-way valve can operate up to 350 bar operating pressure on channels 2, 3 and 4, and 250 bar on channel 1 – values that are not achieved by most products on the market. Tested on a proof-of-concept basis, the valve achieves 10 million switching cycles, making it suitable for very demanding applications.

The pressure drop at 10 l/min is 3 bar, at 30 l/min 10 - 20 bar, depending on coil type and flow direction.

The compact dimensions of the SD2E-A4/H3 make the valve particularly suitable for mobile machines where installation space is usually limited. The zinc-coated housing has withstood 520 hours in the salt spray test (according to ISO 9227).

Your advantages:

  • High flow rate
  • High operating pressure
  • Less space required due to compact housing
  • Corrosion resistant surface
