Custom electric wafer butterfly valve
Custom electric wafer butterfly valve is a soft sealing valve for installation with flanges
drilled in accordance with AS 2129 Table E, available in sizes 50mm through
to 300mm. The Arita butterfly valves are a high performance valve, designed
for a long service life.
Butterfly valves are fitted with the TN series quarter turn electric
actuators which are available in either a basic or smart model.
The basic model is constructed with internal mechanical cams to stop the
motor in the required position. It offers a number of standard features such
as a brushless motor, overload protection, IP67 rated housing, dome style
visual indicator, manual override, end of stroke switches, anti-condensation
heater, and a variety of voltages and wiring configurations.
Smart model is fully electronic using magnetic positioning and operates
using inbuilt firmware. In addition to the standard features, the smart
model features an OLED screen which can display position indication,
failure reports, along with menu operation and push button control to allow
numerous advanced operations such as custom positions, speed control,
local manual control, and more.
