DAC Worldwide’s ACR Manual Balancing Valve Cutaway (373-551) is a professionally sectioned example of a manual balancing valve commonly used in hydronic heating and cooling systems.
Manual balancing valves allow technicians to adjust water flow through terminal devices, heat-transfer coils, and branch circuits. Proper hydronic balancing helps each part of a system receive its required flow, supporting efficient heat transfer, occupant comfort, and dependable system performance.
The valve also includes two pressure-measurement ports. Technicians can measure the differential pressure across the valve and use the valve setting and manufacturer’s flow data to determine the approximate flow rate.
A carefully planned cutaway of the valve body and seat area reveals the stem, seat, adjustment mechanism, pressure-measurement channels, and complete flow path. Painted cutaway surfaces and color-coded components make the valve’s internal construction and operating relationships easier to identify.
The ACR Manual Balancing Valve Cutaway helps learners visualize how changing the valve position affects flow resistance and pressure differential. It supports instruction in hydronic system balancing, component identification, flow measurement, valve adjustment, maintenance, and troubleshooting.
The full-size cutaway is mounted on a modular display panel for convenient classroom and laboratory use. It can be used with compatible tabletop mounting fixtures or combined with other DAC Worldwide cutaways on optional display and storage assemblies.
The equipment is cleaned, primed, and finished with a durable urethane coating to withstand frequent use. Carefully selected cutaway areas expose the valve’s primary components while preserving their relationship and operating characteristics.
Pair the ACR Manual Balancing Valve Cutaway with additional DAC Worldwide HVAC/R cutaways to compare valve construction, flow-control methods, operating principles, and system applications.
