Precise, reliable, and consistent positioning of control valves is of critical importance in maintaining overall process control. Beck’s unique ability to quickly, accurately, and consistently track the control signal allows you to fully utilize your control system’s capabilities. This can significantly decrease process variability, improve product quality, and reduce operating costs.

Group 11 valve drives are engineered for direct coupling on quarter-turn ball, plug, and butterfly valves. They may also be installed using specially engineered crank arm and linkage arrangements.

Valves and drives may be ordered together as pre-engineered assemblies ready for drop-in installation. Or drives can be supplied separately along with the necessary hardware for field installation on existing valves.

A competent diagnostician would be able to determine if the wiring to the valves is good (a gopher can chew the wire and ruin your day). If one of the wires (say the common) is chuffed, but you have multi-conductor and another wire is available, proper marking (coloured shrink tubing rocks for this), and you can swap to another wire.
In the meantime, if your irrigation valves have manual actuators on them, you should be able to flip them on manually so that plants still get watered - you just have to remember to turn them off too.
I just re-plumbed the 1/2" dripline supply run for a row of rose bushes in front of my house (was easier to pull out all of the original dripline when I went to do a wood-chip project, rather than to work around the dripline), but I had the...
