• What are the differences between N.C. (Normally Closed) and N.O. (Normally Open) valves?

         Normaly Closed vaves remain closed when power off and open only when power on.

         Normaly Open valves allow flow by default and close when power on.

• What is the IP (Ingress Protection) rating of this valve?

         IP67. For permanent outdoor installation, they should be installed under a cover or within a protective enclosure to avoid prolonged exposure to rain.

• Is this valve certified for potable water?

         Yes. Flomarvel stainless steel ball valves are certified to NSF 61 and are approved for safe use with potable (drinking) water.
