THIS PRODUCT HAS BEEN REPLACED BY TYPE NRFA-S2

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

Actuator version NC - closed without voltage.

The actuator is exclusively compatible with Belimo ball valves. The actuator 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. Interrupting the power supply turns 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 needed 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 a manual lever. Unlocking is done manually or automatically by supplying power.
• The actuator is protected against overload, requires no end stops, and automatically stops at the stop.
