Pump group with mixing valve and actuator ESBE GRA211 ARA661+VRG432-25-WILO 61042100

The ESBE GRA200 series are pump groups intended for heating circuits where excellent flow and temperature control is required. They are equipped with two shut-off valves with thermometers, a non-return valve, high insulation and a high-performance circulation pump. The units are supplied with a 3-way rotary progressive mixing valve which ensures the best regulation regardless of flow rate and reduces the risk of oversizing.

The GRA200 series is supplied with the ARA661 series actuators with a 230 V AC 3-point control signal or the ARA639 series actuators with a 24 V AC/DC proportional control signal. Pump groups are available in sizes DN25 and DN32 with a Wilo or Grundfos pump.
