Rotary actuator with NRFA fail-safe function for Belimo two- and three-way ball valves. It can be used both for open/closed versions and for control versions of ball valves.

NC drive version - normally closed.

The actuator is only compatible with Belimo ball valves. The actuator cannot be used for valves of other manufacturers!

Features

  • The actuator moves the ball valve to the operating position at the same time as tensioning the return spring. The ball valve is turned back to the fail-safe position by spring force when the supply voltage is interrupted.
  • Simple direct mounting on ball valve with one screw. No additional adapter required. The mounting position in relation to the ball valve can be selected in 90° steps.
  • By using the hand crank the valve can be operated manually and egaged with the locking switch at any position. Unlocking is carried out manually or automatically by applying the operating voltage.
  • The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.
