The HONEYWELL S245 B-1/2″ is a heavy-duty industrial safety relief valve engineered for accurate overpressure protection in process and pneumatic systems. It features a direct spring-loaded, diaphragm-actuated design that opens at a preset pressure to vent excess fluid, then reseats automatically to maintain system integrity.
