DAC Worldwide’s ACR Straight-Thru Pressure Relief Valve Cutaway (373-506) is a professionally-crafted, sectioned example of a commonly-encountered straight-thru relief valve used in refrigeration systems to protect liquid receivers from being over-pressurized. The relief valve also protects other system components from compressor over-pressure. These safety-related, automatically-triggered relief valves often require troubleshooting and/or replacement after discharge due to seat obstructions.

A full cutaway view of the valve body and seat area exposes the complete internal design, including seat, spring, seat disc, and adjusting gand. Cutaway surfaces are enhanced through painting, making the geometry of all components more clear. Multiple cutaways unveil all internal components, which enhances classroom training in HVAC system design, maintenance, troubleshooting, and preventive/predictive maintenance.

The full-size, fully-detailed example gives learners a first-hand view into a component that is found in various applications worldwide. This professionally-crafted, yet-economical component sample will enhance HVAC training activities in both the industrial and the educational setting.

Enhance Training with Hands-On Cutaway Industrial Components

This ACR Straight-Thru Pressure Relief Valve Cutaway provides a full cutaway view of the reversing valve that exposes the complete internal components and operating principles. Mounted economically on a formed-steel and powder-coated modular display panel, this sample panel can also be mounted on a variety of optional benchtop display fixtures and storage structures.

The cutaway features carefully-planned cutaway areas that are individually mounted, and possess the ability to be removed from the baseplate for convenient classroom use. All of the cutaway’s components are also visible and have been retained, enhancing students’ visual learning. This carefully-crafted teaching aid will support instructor-led training and independent student self-discovery in a variety of vocational and academic air conditioning and refrigeration programs.

The equipment used within the cutaway is cleaned, primed, and painted using a high-endurance urethane coating, providing durability to stand up to frequent use. In addition, all of the component parts are color-coded to enhance the learning process.

Expand Training with Additional HVAC Model Options

The ACR Straight-Thru Pressure Relief Valve Cutaway is only one of DAC Worldwide’s expansive HVAC training cutaways, which includes an ACR Steel Ball Valve Cutaway (373-501), an ACR Solenoid Valve Cutaway (373-502), an ACR Packless Diaphragm Line Valve Cutaway (373-503), a Heat Pump Reversing Valve Cutaway (373-505), and more!


DAC Worldwide's HVAC cutaways enhance learning by providing a look inside components found in most HVAC systems including compressors, solenoids, and valves. On many of DAC Worldwide's cutaways, functionality has been retained and a hand wheel provided to demonstrate low-speed manual operation. Each cutaway is mounted on a modular, heavy-gauge steel baseplate and support assembly. For industrial training relevance, common models by well-known manufacturers are chosen.
