Lift Check Valves – Pressure Seal, Y-Pattern (ASME)

Lift Check Valves – Pressure Seal, Y-Pattern (ASME)

MSS-SP-144 Design | Optimized for High-Pressure & High-Temperature Horizontal Flow Applications Valvosider Y-Pattern Lift Check Valves with Pressure Seal Bonnet are engineered to prevent backflow in high-pressure, high-temperature horizontal pipelines, especially in power generation and process applications. The Y-pattern body reduces turbulence and pressure drop, while the spring-loaded disc ensures prompt closure under reverse flow. With a compact layout and pressure-energized bonnet, these valves are suitable for systems where reliability, longevity, and space-efficiency are critical.
