I am designing a system utilizing a 60,000 gallon above ground tank per NFPA 22 and would like to locate a supplier for a listed indicating control valve for automatic filling of the tank.
Thank you lightecho. I had read the post and already knew there was no butterfly vavle w/actuator listed for the service. I have a supplier trying to push an Inbal deluge type valve for tank filling and the AHJ and I have some reservations. I was looking for other suggestions
