What it is

The Belimo R3020 4S2 is a three-way control valve (CCV) with a DN20 body and Rp 3/4" threaded connections. It is a Belimo valve intended for modulating control of flow in heating, ventilation and air conditioning circuits. The three-way configuration allows either mixing or diverting duty depending on how the ports are piped.

Before you order

  • Confirm the pipework is DN20 with Rp 3/4" parallel threaded tails.
  • Check whether the circuit requires mixing or diverting operation before selecting the port arrangement.
  • Verify the actuator mounting and stroke match the valve body already in use, or the intended actuator for the installation.
  • Check the existing valve marking against the R3020 4S2 reference to ensure the correct body is supplied.
