DAC Worldwide’s ACR Packless Diaphragm Line Valve Cutaway (373-503) is a professionally sectioned example of a packless diaphragm valve commonly used in air conditioning and refrigeration systems. These multi-turn, globe-style valves may serve as maintenance-related block valves or system flow-control valves.
Packless diaphragm line valves are frequently used to isolate HVAC/R suction, discharge, and liquid lines during maintenance and repair. They may also support refrigerant charging, evacuation, and purging procedures.
A carefully planned cutaway of the valve body and seat area reveals the internal stem, seat, spring, backseat, diaphragm, and flow path. Painted cutaway surfaces and color-coded components make the geometry and relationship of the valve’s internal parts easier to identify.
The ACR Packless Diaphragm Line Valve Cutaway helps learners understand how movement of the valve stem and flexible diaphragm opens, restricts, or closes the refrigerant flow path. The sectioned valve provides visibility into its internal construction while retaining its operational characteristics for demonstration.
The full-size industrial component supports instruction in HVAC/R system design, valve operation, refrigerant-flow control, maintenance, troubleshooting, and preventive and predictive maintenance.
The cutaway is mounted on a formed-steel, powder-coated modular display panel suitable for tabletop use. The panel can also be used with compatible DAC Worldwide display fixtures, storage structures, and workstation products.
The equipment is cleaned, primed, and finished with a durable urethane coating to withstand frequent classroom and laboratory use. Its carefully selected cutaway areas provide a clear view of the valve’s primary components and operating principles.
Pair the ACR Packless Diaphragm Line Valve Cutaway with additional DAC Worldwide HVAC/R cutaways to compare valve designs, internal components, operating principles, and system applications.
