CDI SW12-1-1/4-NPT-200PSI Safety Pressure Relief Valve

CDI SW12-1-1/4-NPT-200PSI Safety Pressure Relief Valve is a brass-bodied ASME‑code pop-off relief valve designed for high-flow protection in compressed air systems. It features a 1-1/4 in NPT inlet (MNPT) and a preset relief pressure of 200 psi, with a soft-seat seal for bubble-tight operation and reliable reseating after discharge. The valve supports flow up to about 1,624 CFM at set pressure and is rated for service up to 250°F, making it suitable for air lines, tanks, and other pressurized-air applications that require rapid overpressure protection. Built to ASME standards, it employs a stainless steel spring and silicone O‑ring to maintain performance in demanding environments.
