Compressor service valves, often called King valves, provide controlled access to refrigeration systems for pressure measurement, refrigerant charging, recovery, evacuation, and other service procedures. Their valve-stem position determines the connection between the compressor, refrigerant line, and service gauge port.
DAC Worldwide’s Compressor Service King Valve Cutaway (373-195) is a professionally crafted, sectioned example of a service valve commonly found on open-drive and semi-hermetic refrigeration compressors.
The cutaway retains its operational characteristics while revealing the valve body, internal flow path, valve stem, compressor connection, front seat, backseat, packing, and gauge port. This visibility helps learners understand how valve position affects refrigerant flow and service-port access.
Carefully planned cutaway areas expose the valve’s complete internal configuration. Learners can observe the relationships among the stem, seats, packing, system connection, compressor connection, and gauge port.
The operating stem allows instructors to demonstrate the valve’s primary service positions:
Refrigerant must always be handled and recovered in accordance with applicable safety and environmental requirements.
The cutaway supports instruction in valve construction, system isolation, pressure testing, gauge installation, refrigerant charging and recovery procedures, leak prevention, and routine service-valve inspection.
Cutaway surfaces and selected components are painted and color-coded to make internal geometry, component relationships, and the representative flow path easier to recognize.
The industrial component is cleaned, primed, professionally sectioned, and painted using a high-endurance urethane coating. This durable finish helps the cutaway withstand frequent classroom and laboratory use.
The valve is mounted on a formed-steel, powder-coated modular display panel. It can be used for benchtop demonstrations or mounted on compatible DAC Worldwide display, storage, and workstation products.
