Solution Areas

The Shanghai Rogers Hydraulic Slow-Closing Check Butterfly Valve integrates butterfly, check, and slow-closing functions via hydraulic buffering and multi-stage technology to suppress water hammer (80% pressure peak reduction), backflow, and pressure fluctuations in water treatment, chemical processes, HVAC, fire safety, and pipelines. Rated for -40°C to 180°C, 42 MPa pressure differentials, and corrosive media (e.g., LNG, strong acids), it features Hastelloy/duplex stainless steel options, hard/soft seals for wear/leakage resistance, and adjustable 3-30s hydraulic controls for gas-liquid two-phase flow, high-frequency pump startups, and long-distance transmission. API/ISO compliance ensures reliability in high-drop pipelines and critical industrial systems.
