Will the electric valve automatically close after a power outage?

Delcofluid valves indicate that electric valves can be roughly divided into two categories: one is valves with fail safe function, and the other is valves with fail to last position or fail locked.

(1) Fail Safe valves:
① This type of valve is designed to automatically return to a preset safe position, usually in a closed state, when power supply is lost.
② This design is crucial for preventing medium leakage and protecting downstream equipment or the environment, especially when dealing with toxic, flammable, or high-pressure fluids.
③ The multiple electric valves provided by Delcofluid all have this function, which ensures rapid and reliable closure in the event of power failure through built-in spring mechanisms or gravity, safeguarding the safety of users’ production.

(2) Fail to Last Position or Fail Locked valves:
① Unlike fail safe valves, this type of valve will remain in its current position after a power outage, whether it is open or closed.
② This feature is equally important in certain application scenarios, such as systems that require maintaining specific flow or pressure conditions.
③ Delcofuli also offers such valve options to meet the specific needs of different users.
④ When making a choice, users need to carefully consider the system requirements and may need to configure backup power or manual operation devices to cope with possible power outages.
