2-Piece Threaded Ball Valves with Spring Return Levers (also known as "Deadman" valves) are critical safety components designed for automatic closure. The spring-loaded handle ensures the valve returns to the fail-safe position (usually closed) the moment the operator releases it. This prevents accidental spills or discharge. Built from 316 Stainless Steel with a Full Bore and PN 63 rating, they are ideal for fuel loading, sampling, and hazardous chemical transfer.
