ESBE Valve Sizing & Selection Tool

Enter your system details to calculate the required flow rate and identify suitable ESBE valve options based on application, Kvs and connection type.

What does the valve need to do?

Preferred connection

Power

Temperature Difference (ΔT)

K / °C difference

Flow Rate

m³/h

Enter Power and ΔT to calculate the required Flow Rate. If you already know the Flow Rate, you can enter it with either Power or ΔT to calculate the missing value.

Which flow pattern do you need?

For diverting duty, choose the arrangement that matches the required flow path.

L-pattern VRG130 Common port AB is on the side. Flow is diverted to either A or B. AB → A OR AB → B

T-pattern VRG230 Common port AB is on the branch. Flow is diverted to either A or B. AB → A OR AB → B

I'm not sure Show both options

No problem. We'll show both valve families so you can compare them, or contact B.E.E. and we'll help confirm the correct arrangement.

Simplified diverting diagrams: arrows show the possible flow routes, not simultaneous flow through both outlets. The diagrams may be rotated or mirrored to suit the installation. Always confirm the valve port markings and current ESBE technical documentation.

Do you also need an actuator?

Control signal

Supply voltage

Preferred running time

Auxiliary switch

The correct control signal and voltage must match the controller or system supplying the actuator.

Sizing guidance only: Results are based on the information entered and standard hydraulic calculations. They are intended as preliminary product-selection guidance only and do not constitute a system design or guarantee that a particular valve or actuator is suitable for an installation. Final valve and actuator selection should be checked against the complete system design, required valve function, operating conditions, pressure requirements, required flow pattern, port arrangement, supply voltage, control signal and current ESBE technical documentation before ordering or installation. If you are unsure, please contact B.E.E. for assistance.
