Clippard Instrument Laboratory R331 Delay Valve

The Clippard Instrument Laboratory R331 Delay Valve is a vintage component from Clippard's Minimatic line, identified by the R331 model designation. It functions as a delay valve, providing a timed delay in valve actuation within a control system, a pattern commonly used to sequence events, manage timing in automated processes, and coordinate multiple controls that require a controlled lapse between input and output signals. As part of the Minimatic family, this unit reflects the historical design approach Clippard used for compact, modular control hardware that technicians and engineers encounter in lab and automation environments. The R331 designation identifies the specific model within Clippard's Minimatic lineup, aiding in identification and potential cross-reference with other Minimatic components for system integration.
