Model C – ASME

Model C ASME

The Model C-ASME is the ASME certified version of our angle body Model C relief valve. The Model C-ASME is UD stamped. It holds a bubble-tight, closed position until pressure reaches an exact set point. At set point, the valve instantly opens to relieve pressure from a protected system. The inlet is smaller than the outlet and the valve features a wide variety of pressures ratings and settings.
