Product Description

Normally closed electric motorized ball valve,Auto return electric motorized ball valve automatically returns the valve to its original position when de-energised. The compact design works in the same way as a solenoid valve and can be considered ‘fail safe’ once the storage capacitor has charged up (approx 60 seconds).In the process of field use, sudden emergency fault, in the case of external power outage, power reset series electric actuators of the Normally closed electric motorized ball valve can be immediately valve command, a program to continue to work to the fully open or close the valve state power reduction effect, power is fully open or close the factory can set according to the requirement, the maximum meet the protection requirements of the various special pipeline, Power plants, chemical plants, environmental protection equipment and other industries.

Normally closed electric motorized ball valve Power off reset function

In normal use, in case of emergency, the external power supply must be cut off! Dangerous goods storage tanks, oil pipelines and other occasions in case of emergency valve closed!

Explosion-proof power-off reset actuator automatically operates when the external power supply is disconnected close the valve (power-off on, power-off off) factory setting optional.
