Cast Iron Solenoid Valves

Cast iron 2/2-way solenoid valves are normally closed valves with flanged connections for larger water, compressed air, and oil pipes. Semi-direct versions work from zero pressure difference. Indirect-acting versions require a minimum of typically 0.2 to 0.5 bar (3 to 7 psi).

Flanges and seals

  • Flanges: the nominal size, the flange standard, the bolt pattern, and the pressure rating must match the pipe flange. EN flanges use DN and PN; ASME flanges use NPS and Class.
  • Seal: EPDM is the choice for water; compressed air and oil need NBR or FKM.
  • Corrosive media: cast iron is not suitable for sea water or corrosive media. For these media, choose a housing that resists the medium, for example stainless steel or plastic.
