LF 24-SR • Actuators with spring reset 4Nm modulating 0-10V

Servomotor with spring return for air volume safety dampers of up to 0,8 m² depending on the type of air valve and the pressure on the valves. Simple direct mounting on the damper axe with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating.

Brand

  • Belimo

Application

  • Safety dampers

Specifications

  • Torque 4 Nm
