The company now offers a line of 2- to 12-in. electronic and pneumatic butterfly valves. These two- and three-way valves are for applications requiring two-position (on-off) and modulating control, such as flow control of hot water, condenser water, thermal storage systems, and steam applications. Two body styles are offered: wafer and lug. The lugged body is drilled and tapped to provide for removal of downstream piping at full pressure, says the company. A standardized cast-in top plate on the body allows for direct mounting of the actuators, the company says.
