THIS PRODUCT HAS BEEN REPLACED BY TYPE NRFA

Rotary actuator with emergency function NRF for two-way and three-way Belimo ball valves. It can be used for both open/close versions and regulating versions of ball valves.

Actuator version NC - closed without voltage.

The actuator is exclusively compatible with Belimo ball valves. It cannot be used on valves from other manufacturers!

Features

• The actuator drives the ball valve while simultaneously tensioning the return spring to the operating position. Interruption of the power supply rotates the ball valve back to the emergency position using the spring's energy.
• Simple direct mounting on the ball valve using a single screw. No additional adapter is required for installation. The mounting position is selectable in 90° increments relative to the ball valve.
• The ball valve can be adjusted and fixed in any position using the manual lever. Unlocking is done manually or automatically by applying power.
• The actuator is protected against overload, requires no end stops, and automatically stops at the stop.
