Kromschroder Valve Train

  • The standard Kromschroder valve train, sized 1/2” through 2”, uses Kromschoder’s VAS / VAD 1-3 solenoid valves and associated attachments.
  • The valve trains are designed for [24VDC][120VAC 50/60 Hz][230VAC 50/60Hz][120-230VAC 50/60Hz] operation.
  • Included in the valve train are a 12-44” w.c. high pressure switch and a 3-17” w.c. low pressure switch.
  • The valve train does not increase in length when ordered with the optional pressure regulator.
