Viti Fluid Control - Specialized Fluid Solutions for Thermal Power and Cogeneration Industries - Providing reliable full-process support for steam-water systems, circulating water, desulfurization and denitrification in power plants

Electricity is the lifeblood of industry, and valves are the "joints" of power plants. In the thermal power and cogeneration industries, the failure of a single valve may lead to unplanned shutdowns of the unit, equipment damage, and even safety accidents. Viti Fluid Control, relying on Germany's precision manufacturing genes and decades of in-depth experience in the power industry, provides professional and full-process fluid control solutions for steam-water systems, circulating water systems, and desulfurization and denitrification systems in power plants.

I. Steam-water System: A reliable guardian for high-temperature and high-pressure working conditions

The steam-water system is the core thermodynamic cycle system of a power plant, with the medium mostly being high-temperature and high-pressure steam and feed water. It has extremely high requirements for the high-temperature resistance, high-pressure resistance, erosion resistance and zero leakage performance of valves.

Typical application scenarios

Main steam system

Reheat steam system

Boiler feed water system

Temperature and pressure reducing device

Bypass system

Hydrophobic system

Vitite's core products and advantages

Product series	Key performance	Technical highlights
High-temperature and high-pressure stop valve	Temperature resistance ≤610℃, pressure resistance ≤42MPa	The valve seat is surfacing with cobalt-based hard alloy, which is resistant to scratches and erosion
Labyrinth sleeve multi-stage pressure reducing regulating valve	Anti-cavitation and anti-flash evaporation	The labyrinth sleeve decomposes the high pressure difference into multiple stages of pressure reduction, completely taming flash vapor erosion
High-temperature and high-pressure gate valve	Zero leakage opening and closing	Wedge or parallel double gate plate structure, with hard alloy surfacing welded to the sealing pair
Steam conversion valve	Integrated temperature and pressure reduction	Vitai's classic products simultaneously achieve steam pressure reduction and water spray cooling
High-pressure triple eccentric metal hard seal butterfly valve	Bidirectional high voltage with zero leakage	The world's first three-eccentric + surfacing special hard alloy sealing pair is suitable for large-diameter steam pipelines

Customer value

Ensuring continuous operation of the unit: High-quality valves reduce the risk of unplanned outages

Extended maintenance cycle: Wear-resistant and anti-erosion design reduces frequent replacement

Enhance thermal efficiency: Zero leakage sealing reduces energy loss

Ii. Circulating Water System: An economical choice with large diameter and corrosion resistance

The circulating water system is responsible for providing cooling water to equipment such as condensers, oil coolers, and air coolers. The medium is mostly river water, seawater, or circulating water from cooling towers. It has a large diameter and low pressure, but there are clear requirements for corrosion resistance and reliability of opening and closing.

Typical application scenarios

Outlet of the circulating water pump

Inlet and outlet of the condenser

Cooling tower pipeline

Side filtration system

Drainage system

Vitite's core products and advantages

Product series	Key performance	Technical highlights
Centerline soft-sealed butterfly valve	It opens and closes quickly with low flow resistance	Rubber or PTFE lined sealing, anti-corrosion and wear-resistant, with high cost performance
Double eccentric high-performance butterfly valve	Higher pressure resistance and longer service life	The metal + soft seal composite structure is suitable for circulating water containing a small amount of impurities
Rubber-lined butterfly valve	Comprehensive anti-corrosion resistant to seawater and fresh water	The valve body is lined with high-quality rubber, and the butterfly plate is made of corrosion-resistant alloy or covered with nylon
Check valve	Prevent water hammer backflow	It features various structures such as swing type and double plate type, and opens and closes smoothly
Gate valve	Fully open and fully closed, with extremely low flow resistance	Exposed or concealed rod structure, suitable for large-diameter pipelines

Customer value

Economical and reliable: Large-diameter valves offer high cost performance and meet the demands of large-scale applications

Long service life and corrosion resistance: Rubber-lined/plastic-lined design, suitable for corrosive media such as seawater and reclaimed water

Easy maintenance: Simple structure, easy to inspect and repair on site

Iii. Desulfurization and Denitrification System: Special solutions with corrosion resistance and wear resistance

The desulfurization and denitrification system is a key link for power plants to meet environmental protection standards. The media are mostly limestone slurry, gypsum slurry, ammonia water, urea solution, etc., which have the characteristics of strong corrosiveness, high solid content and easy crystallization. This puts forward strict requirements for the corrosion resistance, wear resistance and anti-clogging performance of valves.

Typical application scenarios

Limestone slurry transportation

The gypsum slurry is discharged

Absorption tower circulation pipeline

Ammonia zone/urea solution pipeline

Wastewater treatment system

Vitite's core products and advantages

Product series	Key performance	Technical highlights
Ceramic ball valve	Ultra-high hardness and extremely strong wear resistance	The entire flow channel is lined with ceramic, and both the ball core and the valve seat are structural ceramics, which are resistant to erosion by gypsum slurry
Ceramic butterfly valve	Large-diameter wear-resistant solution	Wafer-type structure, with all parts in contact with the medium lined with high-performance ceramics
Rubber-lined/fluorine-lined diaphragm valve	Comprehensive anti-corrosion, no blind spots	No packing seal, the medium is isolated from the valve body, suitable for limestone slurry
V-type ceramic ball valve	Dual functions of regulation and cut-off	The V-shaped cut ceramic ball core has self-cleaning function and is anti-clogging
Wear-resistant and corrosion-resistant ball valve	Strong acid and alkali combined with high wear working conditions	The world's unique special base material and processing technology have passed the 2880-hour dilute sulfuric acid extreme test
