New line of directional solenoid valves and pressure relief valves in stainless steel execution for corrosive environments.

Stainless steel solenoids , ex-proof Atex, IECEx or C UL US, for hazardous areas -see section 3.

Two executions are available:

  • X stainless steel for external and internal parts, to withstand extreme and corrosive environmental conditions, and to ensure full compatibility also with water base and special fluids.
  • XS stainless steel for external parts to withstand extreme and corrosive environmental conditions.

Internal components are derived from standard valves.

Directional valves are available in two basic versions: poppet type, 3-way leak free (suitable for accumulator systems) or spool type, 4-way on-off valves.

Explosion proof solenoids  with:

  • ATEX 94/9/CE certification, protection mode
    • Ex II 2GD, Ex d IIC T6/T4/T3, Ex tD A21 IP67
  • IECEx worldwide recognized safety certification, Ex d IIC T6/T4/T3, Ex tD A21 IP67
  • C UL US certification, according to UL 1002 and CSA 22.2 n°139-1982 class I Group C & D (Group IIA & IIB to NEC 505-7)

DHAX and DLOHX valves conform to SIL 3 safety level (TÜV approved).
