For the most part you are correct, but Victaulic does make a listed ball valve that is "slow close and indicating. It's a model #728. There may be others. Obviously this is not the run of the mill ball valve in discussion, but they do exist. http://www.victaulic.com/Docs/lit/10.17.pdf Best Regards, Ken Holsopple Rowe Sprinkler Systems, Inc. _______________________________________________ Sprinklerforum mailing list Sprinklerforum@firesprinkler.org http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: supp...@firesprinkler.org To Unsubscribe, send an email to:sprinklerforum-requ...@firesprinkler.org (Put the word unsubscribe in the subject field)
