It has a 90° elbow outlet with a Victaulic grooved connection for 4" piping, an integrated external exhaust to isolate the valve's exhaust, and a mechanical jack screw for manual opening if air pressure is lost. Designed to shear at a groove during an accident, the valve automatically closes to prevent product loss, and it includes a fusible plug that melts at 212°F as a fire safety measure. The aluminum body and poppet, stainless steel shaft, and Tef‑O‑Sil (Teflon encapsulated) seals make it compatible with diesel, biodiesel, gasoline, ethanol, and methanol.
