Fail-safe versions use capacitors to store energy to move the actuator to its fail-safe position in the event of a power failure. Not using a spring enables the use of a smaller motor and increases its life by up to six times.
Neptronic has been a leading US manufacture of actuators and actuated valves for 15 years.
There are digital and analogue rotary and linear actuators for dampers, multi-signal actuators, high-torque actuators and fast actuators for applications such as fume hood cupboards.
Complete actuated valves include 2- and 3-way actuated ball valves, globe valves and butterfly valves. Retrofit kits include actuator and linkage for assembly to globe valves, ball valves and butterfly valves.
