The Kunkle 6283H1 Relief Valve is a spring-loaded safety device designed to protect pressure vessels and piping from overpressure, delivering 433 cfm of relief capacity at a 15 psi set pressure. It features NPT threaded connections sized 1-1/2 in and 2-1/2 in, enabling straightforward integration with common piping. When system pressure reaches the set pressure, the valve opens to relieve excess pressure and reseals automatically once the flow subsides. Common applications include air compressors and air receivers that require a 15 psi relief threshold to maintain safe operating conditions.
