Engineered in accordance with ASME Section VIII standards, the Type 13900 Series pilot-operated safety relief valves deliver superior flow capacity alongside a streamlined structural layout. Each unit comprises a compact fail-safe pilot valve paired with a large-flow main valve module. The main valve supports orifice areas as large as 200 square inches, cutting down the total valve quantity needed to safeguard systems against overpressure risks.
