Cla-Val Models 139-10 and 639-10 are on-off timer-controlled valves for applications requiring a programmable time schedule. The valves’ pilot system, featuring the programmable CTC-33 Electronic Timer Control, enables up to three opening and closing sequences per day and can be set-up for a weekly schedule.

Timer function and parameters are changed using downloadable software from the Cla-Val website www.cla-val.com and special USB cable (part number 20519203A). Future software and firmware upgrades will be available from Cla-Val website. Powered by a long-life lithium battery, the CTC-33 control offers powerful valve control for remote locations and other valve automation applications.
