What problems are most feared when importing high-temperature and high-pressure valves? How to avoid it?

Users are most concerned about three issues: insufficient reliability, lack of performance, and inadequate after-sales service. Many domestic valve manufacturers meet the laboratory data standards, but after one or two years of on-site operation, internal leakage, jamming and erosion of the sealing surface occur. The way to avoid it is very simple - look at the real performance, ask about the running time, and check the user reviews.

Viti has a large number of traceable operational achievements in the field of high-temperature and high-pressure valves:

Main steam/feed water system: Stop valves, check valves, and labyrinth sleeve control valves are used in 660MW and 1000MW ultra-supercritical units (such as the 2×1100MW of Xinjiang Sixth Division, equipped by Shanghai Electric)

Steam trap system: Y-type steam trap, free float type steam trap. The patented pressure reducing protection device effectively prevents erosion of the sealing surface, and its service life far exceeds that of conventional steam traps

The desuperheating water system: superheater/reheater desuperheating water regulating valve, multi-stage pressure reduction structure, has been stably operating in many supercritical units for a long time

Flexibility modification (cylinder cutting) : Large-diameter three-eccentric metal hard-sealed hydraulic butterfly valve (DN1400 and above), featuring regulation + quick closing + zero leakage functions, is used for near-zero output modification of low-pressure cylinders

Viti also offers "full life cycle services" : from the initial diagnosis of working conditions and selection calculation, to on-site installation guidance and commissioning, and then to long-term spare parts supply and maintenance. The technical team promises to respond to on-site demands within 24 hours, completely resolving users' pain points of "being able to afford it, not being able to use it, and having it repaired slowly".
