type 13900 Series POSRV

Type 13900 Series Pilot-Operated Safety Relief Valves

The Type 13900 Series pilot-operated safety relief valve combines high capacity with simple construction, designed to ASME section VIII. It consists of a small conventional, fail-safe pilot valve and a high capacity main valve platform. The main valve can be configured with orifice sizes up to 200 square inches to help reduce the number of valves required for system overpressure protection.
