Failsafe Electric Ball Valves – Spring Return Motorised Valves
Failsafe electric ball valves (spring or backup power return motorised) are designed to automatically open or close on power failure, ensuring safe shutdown or flow protection in critical systems.
Available in fail-safe closed (power to open) and fail-safe open (power to close) configurations, these valves are ideal for water, air and industrial process applications where electrical control and safety are required.
Our range includes compact electric capacitor return actuators with brass, stainless steel and UPVC valve bodies, plus WRAS approved options for potable water use.
👉 All valves are stocked in the UK with free next day delivery.

⚙️ How Electric Failsafe Ball Valves Work
Electric failsafe ball valves use a motor-driven actuator with Farad Capacitor return mechanism.
Operation:
→ Under power: motor drives valve open or closed
→ On power failure: internal reserve power returns valve to safe position
Available configurations:
→ Fail-safe closed (power to open)
Closes automatically on power loss (most common)
→ Fail-safe open (power to close)
Opens automatically on power loss

❓ FAQs (Electric Focus)
What is an electric failsafe ball valve?
A motorised valve that automatically returns to a safe position using a spring or power reserve when power supply is lost.
What happens when power fails?
The spring or battery reserve power the actuator returning the valve to its fail-safe position (open or closed).
What voltage options are available?
Most models are available in 110-230V AC and 9-24V AC/DC.
Are WRAS approved electric failsafe valves available?
Yes, WRAS approved models are available for potable water systems.
Are pneumatic failsafe valves available?
Yes, but electric motorised valves are the most common and widely used.
