DAC Worldwide’s Condenser Pressure Control Valve (KVR) Cutaway (373-519) is a professionally-crafted sectioned cutaway of a commonly-encountered condenser pressure control valve, otherwise known as a “head-pressure control valve”. These industrial valves are used in air conditioning and refrigeration systems in order to maintain constant and sufficiently high pressure in air-cooled condensers.
The cutaway unveils the operating principle of the device, wherein changing ambient temperature and condensing pressure causes the valve to throttle via differential pressure and opening on a rise of inlet pressure. Color coding, flow arrows, and numbered call-outs combine to make the device more informative to the inquiring student and more useful to the instructor.
A full cutaway view of the valve body and seat area exposes the complete internal design, including an adjusting spring, seating desk, seat, equalizing bellows, and complete flow path, all while providing access to the setting screw. 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 any training activity relating to commercial and industrial air conditioning and refrigeration systems.
This Condenser Pressure Control Valve (KVR) Cutaway provides a full cutaway view of a control valve that exposes the complete internal components and operating principles. The device can be used independently using an optional tabletop mounting foot, or combined with similar devices on optional display and storage frame assemblies.
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.
The Condenser Pressure Control Valve (KVR) 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), a Heat Pump Reversing Valve Cutaway (373-505), and ACR Magnetic Check Valve Cutaway (373-510), 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.
