The Ware Mod-V was our solution to the boiler industry for a replacement boiler feedwater valve. It solves many of the problems that other valves seem to have. Our design offers 100% shut off as well as repeatable reliability. The actuator is a Honeywell modulating motor that is made to operate either off a 4-20ma signal or a 0-135 ohm McDonnell Miller 7-b switch. Options available in 120v, 24v, and electropneumatic.
