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.

Four Function Valve,  PVDF/AFLAS <250PSI

Four Function Valve, PVDF/AFLAS <250PSI

Material: W2T448111

The Four Functions: Anti-Siphon - The discharge flow path goes through a port that only opens on the discharge stroke of the pump. This prevents the discharge line from siphoning liquid from the supply tank in most applications. Back Pressure - The diaphragm that controls anti-siphoning creates approximately 20 psi (1.4 Bar) back pressure on the pump's discharge valve which improves system performance. Pressure Relief - A second diaphragm protects the pump from overpressure by releasing fluid to a relief port in the event of excessive discharge line pressure. Pressure Release - This function makes it easy and safe to depressurize the discharge line without loosening tubing or fittings.

**Valve comes with 1/2" MNPT connections. The appropriate sized tubing connection kit must be ordered separately**
