DAC Worldwide’s Condenser Pressure Control Valve (KVR) Cutaway (373-519) is a professionally sectioned example of a condenser pressure regulator commonly used in air conditioning and refrigeration systems. Also known as a head-pressure control valve, this device helps maintain adequate condensing pressure in systems equipped with air-cooled condensers.
Changes in outdoor temperature can significantly affect condensing pressure. The KVR valve responds to inlet pressure by throttling refrigerant flow from the condenser, helping maintain a sufficiently high and stable condensing pressure under changing operating conditions.
A carefully planned cutaway of the valve body and seat area reveals the adjusting spring, seating disc, valve seat, equalizing bellows, setting screw, and internal flow path. Color coding, directional-flow arrows, and numbered callouts make the valve’s construction and operating principles easier to interpret.
The Condenser Pressure Control Valve Cutaway helps learners visualize how inlet pressure, spring force, and bellows movement affect the position of the valve. As inlet pressure rises, the valve opens farther; when pressure falls, the valve throttles toward the closed position to help maintain the desired upstream pressure.
The exposed internal configuration supports instruction in condenser pressure control, valve adjustment, component identification, refrigerant-flow direction, system operation, and troubleshooting.
The full-size cutaway can be used independently with a compatible tabletop mounting foot or combined with other DAC Worldwide cutaways on optional display and storage frame assemblies.
The equipment is cleaned, primed, and finished with a durable urethane coating to withstand frequent classroom and laboratory use. Carefully selected cutaway areas expose the valve’s internal components while preserving their relationship and operating characteristics.
Pair the Condenser Pressure Control Valve Cutaway with additional DAC Worldwide HVAC/R cutaways to compare refrigerant-control valves, internal components, operating principles, and system applications.
