  • Materials: 316SS, brass, teflon
Applications:
  • Wet stations
  • Shipboard water systems
  • CVD furnaces cooling water
  • Biomedical instruments
  • Vacuum systems
  • Coolant failure alarm
Operations:

With no flow present, the magnetic piston rests on the bottom of the bypass bore. When flow is established the piston is forced upward by the bypass flow and actuates the reed switch. The bypass flow is controlled by manual adjustment of the flow control vane. When flow decreases the piston moves downward and the reed switch deactuates.
  • Acutation points for air at 68° F and 14.7 psia with increasing flow
  • Deactuation (decreasing flow) averages 10% less than actuation (increasing flow)
  • Repeatability ± 2%
  • Unit will pass greater flows
