Product details

The AVA B80 is our Basic 80Nm entry-level electric actuator. The B80 Series offers 80Nm torque output as standard, with an IP67 rated PC+PET plastic housing, manual override, end of travel limit switches and internal heater. The actuator is to be used for ball and butterfly valves and has an ISO 5211 with F05/07 x 17mm mounting for direct mount to valves. The standard function is On Off. 

The AVA B80 can be upgraded to a Failsafe function using an internal Capacitor Failsafe system. This is an internal capacitor can achieve Failsafe Open or Failsafe Closed on loss of power. We can also offer Hi Speed series for quick actuation time of 0-90 degrees in around 5 seconds. 

See our S80 Smart Series for Modulating function and other ‘Smart’ features including BUS, Timer and Modulating Failsafe, Multi Turn and now EXD series is also available. 

* Please note that if you have previously purchased a 60 Series actuator (B60 or S60) this has now been replaced by our 80 Series following the launch of our new 50Nm actuator series. The 80 Series is a direct replacement, like for like just with more torque output. 

Product options

Standard Open/Close, power to open, power to close. Stays put on loss of power.

Fail closed on loss of power. Internal super capacitor is charged whilst power is applied, when removed, the capacitor will close the actuator. Fail open also available

Fast acting open and closing time available, as standard the run time is typically 50% less than the standard run time. For 10, 20 and 50Nm series, 1 second is available using 24VDC motor.

All our actuators have open and close feedback. If using a Basic actuator this is via mechanical switches. If using our Smart series, this is achieved via electronic relays. Note that our Modulating actuators do not have end of travel feedback, they have a modulating output for example, 4-20ma input + output.

All actuators have manual override as standard. Each actuator is supplied with an allen key to be used when power is NOT applied. You must disconnect power to use the mechanical manual override. For Smart series you also have Local Control manual override.
