Quick guide from the manual

This document provides instructions for installing coupling accessories for Danfoss HRB and HFE valves. Proper installation ensures correct operation of the actuator with the valve. Always verify your specific valve model against the compatibility list before beginning installation.

Kit Selection

Identify the correct kit based on your valve model:

  • 082G4235: Compatible with HRB 3 and HRB 4 valves.
  • 082G4230: Compatible with HFE 3, HFE 4, HRE 3, and HRE 4 valves.

Valve Alignment

Before mounting the actuator, the valve must be set to the correct position:

Practical help

Common problems

Incorrect kit selection

Verify your valve model number (e.g., HRB 3, HFE 4) against the compatibility table in the manual before starting.

Valve not aligned correctly

Ensure the valve is set to the 0% or 100% position before attempting to mount the actuator.

Before use

  • Identify your valve model (HRB or HFE series).
  • Select the correct kit (082G4235 or 082G4230).
  • Verify the valve position (0% or 100%).
  • Ensure the actuator scale is set correctly.

Images and diagrams

  • The kit selection table helps match the valve model to the correct accessory kit.
  • Step 2 diagrams illustrate the required valve alignment positions (0% vs 100%).
  • Step 3 diagrams show the physical assembly order of the coupling and actuator.

Model compatibility

  • Kit 082G4235 is specific to HRB 3 and HRB 4.
  • Kit 082G4230 is specific to HFE 3, HFE 4, HRE 3, and HRE 4.
  • Valve models HRB 3, HRB 4, HRE 3, and HRE 4 produced after 2008 are supported.
