Problem Solving Compact Industrial Electric Actuators
Failsafe electric actuators divide engineers and specifiers as the more popular system over the
last 15 years of a trickle charged industrial battery back-up system, is falling out of favour due
to the security issues around transporting battery operated systems by air. Mechanical failsafe
actuators using springs are an expensive and heavy alternative. The AVA failsafe actuator
employs internal capacitors to store the energy needed to create the failsafe movement, these
simple electronic components are light, are free of security issues, and very cost effective.
Problem solved.
Just two of our varied range of electrically actuated ball valves: a J+J J3C series electric actuator and an AVA basic electric actuator, both fitted to 2″ brass ball valves
