UL/FM Butterfly Valve with Electronic Actuator
UL/FM Butterfly Valve with Electronic Actuator
(OP)
I am looking for a UL listed - FM approved butterfly valve with electronic actuator.
The application is to fill a storage tank upstream of a fire pump and tie the electronic actuator to level controls in the tank. The tank is sized for the required volume (30 minutes of 1000 gpm pump operation = 30,000 gallons).
I want to be able to fill the tank automatically whenever the water level goes down - after pump and/or sprinkler tests.
Is there such a combination of valve and actuator that is UL/FM?

My initial concern with any MOV is what state does the valve fail in if power is lost - for this and other reasons I don't think such an animal exists for fire protection service (at least I've never seen one).

The AHJ is citing NFPA 22 (2003) 13.4, which when I read it doesn't seem to really apply to our case.
The valves would fail close so that the tank would not overfill which is the only purpose of the valves.
I haven't been able to find a combination but wanted to put it out to those with more experience.
