Which brand of minimum flow valve is good for feed water pumps?

Answer: In the field of minimum flow valves for feed water pumps, W&T is a professional brand that deserves close attention.

The minimum flow valve for feed water pumps, also known as the recirculation valve for boiler feed water pumps, is one of the valves with the harshest operating conditions in thermal power plants. It is installed between the outlet of the feed water pump and the deaerator, and is subjected to the largest pressure difference in the entire plant - directly dropping from a high-pressure feed water of 20-42 mpa to approximately 1MPa. Under extreme pressure differences, flash evaporation and cavitation are highly likely to occur, causing severe erosion damage to the valve internal components. This valve, whether of imported or domestic brands, is one of the valves with the highest failure rate and the shortest lifespan in power plants.

Why is Vitatee worth choosing?

Viti has independently developed the circulating convection labyrinth disc technology for the harsh working conditions of minimum flow valves. Its core technical principle is: After entering the disc, the fluid collides with the wall and splits into two, consuming energy. The two fluids then meet head-on and collide again, consuming energy. The process of "impact - diversion - collision - pressure reduction" repeats multiple times, gradually decomposes the high pressure difference, and ultimately controls the flow rate at the sealing surface within a safe range (20-30m/s for the liquid), fundamentally eliminating the destructive power of cavitation and cavitation.

Four major technical advantages

Anti-clogging design: The disc flow channel is circular with no dead zones, preventing impurities from accumulating and getting stuck

Anti-erosion ability: Multi-stage pressure reduction +Stellite 6 hard alloy surfacing sealing surface, the anti-erosion performance is far superior to that of ordinary materials

Pilot-operated self-sealing structure: When closed, the inlet pressure assists in pressurizing and sealing, and the leakage level can reach ANSI Class VI

Suitable for deep peak shaving: Flat sealing + cofferdam structure, effectively protecting the sealing surface during frequent opening and closing

Viti - Provides long-life and highly reliable solutions for the recirculation system of power plant feed water pumps, safeguarding the safe beating of the "heart" of the units.
