B. Shut-off valves

Maxon’s Series 8000 safety shut-off valves have new features designed to keep them your first choice for safety, reliability, and maximized system up-time. Searing heat or bitter cold gives sure closing at temps to -50°C (-58°F) while meeting API 6FA Fire Safe standards. The larger open/closed indicator clearly announces valve position in high-contrast colors. Series 8000 meets tough Class VI leakage standards, carries multiple global endorsements, and are SIL-3 capable.   Unique metal-to-metal seats wear in, not out, with each cycle, and numerous body and trim options provide excellent application flexibility.

D. Steam generator

The FC-OSSG forced-circulation large-capacity steam generator offers up to 250 T/H of steam. With less than 2% blowdown with evaporator water, and 99.5% steam purity, the unit also tolerates substantial upsets in water quality, heat flux, and flow. The FC-OSSG features modern, water-cooled walls and optimized, heat-transfer surfaces, reducing its footprint and weight by 50%. It is specifically designed with significant margins to avoid metal temperature excursions and tube failures. A two-layer defense addresses fluctuations in water quality, increasing reliability compared to traditional OTSGs.
