Motorized ball valve fail-safe option,also named normally closed motorized ball valve,Automatic return electric ball valves,Capacitor Return something like the Spring Return of solneoid valves.Fail-safe normally-open or fail-safe normally-close can be both available,the standard is fail-safe normally-open,please tell us if you need fail-safe normally-open valves.

without the need for the costly and bulky spring return as tradtitional actuator used,Open/close time is approx 5 seconds,No water hammer,can be the best economic alternative to solenoid valves,especially when the solenoid valves can not work reliably.

This serious valves are normally closed valve,it is motor-driven open by voltage and motor-driven closed by way of a built-in capacitor,and it only requires 2 wires to power it.

This actuator is designed so that if power is interrupted to the actuator in the mid-operation,the capacitor will power the valve closed and the valve will not hang-up in the partly open position. The capacitor is quick charging and will fully charge the first time power is applied to the actuator,To guarantee the valve best working performance,please charge it at least 1 minutes when you operate it the first time.

If you need this function,please select CR04 for economic version Tofine-CWX15Q and KT2 for super quality version Tofine-KLD20S

The Wiring is below:

5V,12V,24V,110-120V,220-240V
