Control - We've done the math for you

Properly controlling the flow and temperatures is the central function of an HVAC installation. This means the control valves are crucial and they need to be precisely calculated to achieve optimal working conditions. The AB-QM eliminates the need for sizing calculations for control valves.

Selection of an AB-QM is simplified and eliminates the need to calculate the Cv value of the valve. Instead flow is the important information required to determine the AB-QM valve for the application. Any AB-=QM valve size that satisfies the required flow rate within its setting range can be selected.

This provides greater flexibility in achieving the same flow through different valve sizes of AB-QM. The easy AB-QM setting procedure makes late changes in the design or subsequent system modifications a breeze to implement.

The authority of the valve no longer needs to be calculated because the AB-QM has a unique design that ensures 100% authority with all settings and all differential pressures. This increases the control quality and precision, leading to increased comfort in the building.

Example: Sizing
Traditionally, properly sizing a 2-way valve required information of the flow rate, the pump head, and the resistance within the rest of the system. For the AB-QM, you only need to know the flow requirement.

AB-QM conclusion:
Easy sizing, 100% authority, perfect control.
