LMI 4 Function Valves

LMI 4 Function Valves are compact and economical valves that perform four important functions for your LMI pump:

  • Diaphragm type anti-syphon protection
  • Back pressure
  • Priming aid/line drain
  • Pressure Relief

Priming with the 4FV is simple and achieved by turning of the pressure relief knob (black). 4 Function Valves are a recommended accessory for every LMI electromagnetic pump.
