MCN / MNN SERIES

Semi Lift
Diaphragm Solenoid Valve

A semi-lift diaphragm design that operates from true zero differential pressure — the MCN in CF8/CF8M/brass for air, water, chemical, gas, oil and steam duty, the MNN in nylon glass-filled plastic for lighter water, air and inert gas lines.

Why MNN

Corrosion-Free Plastic Body

  • Nylon glass-filled body eliminates metal corrosion in water and chemical service
  • Zero minimum differential pressure — opens even at 0 bar inlet
  • Lightweight body for irrigation and low-pressure water distribution
