ESBE Mixing Valve for Heat Pumps Higher Flow Systems

High Flow and low Pressure Drop Diverter Valves

Perfect for Higher Flow Rate Systems  
Spring return valves are often used in central heating systems with a boiler as they are designed for lower flow rates, but these are not suitable for higher flow rate heat pump systems as they create a high pressure drop within the system. 

To effectively divert flow from the heat pump to heating or hot water with low pressure drops, a higher KVS (flow rate) valve is required. ESBE diverter valves are designed for managing high flow rates with low delta T to maximise the efficiency of the system, reduce water hammer and avoid breakdowns.

 • Wide range of sizes from DN15 to DN50
 • Connections to suit most pipe dimensions
 • Compact, flexible and easy to install
 • Perfect match with ESBE series ARA600 actuators

Typical Application Schematics

 VRG 131 – L Pattern Valve 

VRG 231 – T Pattern Valve

 ARA Actuator - Internal Jumper 

All ESBE actuators are pre-set in mid-position.  
During set-up, ensure that the valve spindle is in between the two outlet ports prior to mounting the actuator.

To change the switch live direction of travel for DHW demand, an internal jumper within the actuator will need to be altered 90 degrees.
