TORSION spring operators for standard low pressure
butterfly type irrigation valves are described. These
are used with 24-h timers to semiautomate gated pipe
irrigation systems and are particularly well suited for use
with flow-thru single pipeline systems. They are presently
marketed in 150 mm (6 in.), 200 mm (8 in.) and 250 mm
(10 in.) diameter sizes.
