Honeywell V51E Butterfly Firing Rate Gas Valves

Honeywell's V51E butterfly valve is a firing rate valve that provides variable flow control of natural, liquefied petroleum (LP), and manufactured gases. It can also be used to control air flow. The V51E provides high capacity with a relatively constant relationship between flow rate and opening plate angle.

The V51E is actuated by a firing rate motor mounted directly on the valve. It should not be used as a safety shutoff valve.
