PRESSURE SEAL SWING TYPE CHECK VALVE
2"–24", Class 600–2500 pressure seal swing type check valve with self-energizing bonnet seal for reliable high-pressure and high-temperature service.
Product Details
OVERVIEW
The Pressure Seal Swing Type Check Valve operates by the swinging action of the disc away from the seat, allowing forward flow; when flow stops, the disc returns to the seat, preventing backflow. The pressure seal bonnet design ensures total reliability for high-pressure and high-temperature services, with the seal strengthening as internal pressure increases.
Available from 2" to 24" in Class 600–2500 with RF, RTJ, and BW end connections. Available in both forged and cast materials. Suitable for upstream and midstream applications including lines where pigging operations are required for maintenance. Certified to CE/PED, ISO, ATEX, SIL, and NACE MR0175. Supplied with material test certificates (MTC 3.1) and hydraulic test certificates; third-party inspection is available.
