Abstract

PNEUMATIC operators were used to automate low
pressure irrigation butterfly valves. Criteria are
presented for selecting components for this application.
Pilot valves for the automated valve units are battery-powered
and momentarily energized using the electrical
discharge from capacitors. Both mechanical and
electronic timers were used to control the irrigation
valves. Other components in the valve package are
described. Butterfly valves in both single and tee
configurations were field tested.
