Core Technological Capabilities

FLOAUTO has delivered a series of breakthrough innovations in critical severe‑service technologies, achieving major advancements in industrial process control across high‑temperature, high‑pressure, ultra‑low‑temperature, and high‑velocity flow applications. The company has developed and introduced China’s first liquid‑injection control valve and Joule‑Thomson (JT) control valve, both engineered to provide superior performance in gas service, flashing and erosion conditions, severe vibration environments, and high‑velocity nozzle applications. FLOAUTO has also established a robust multi‑stage pressure‑reduction and throttling technology platform, further enhanced through the application of High‑Velocity Oxy‑Fuel (HVOF) thermal spray coatings. This integration delivers exceptional wear resistance, erosion protection, and long‑term reliability for severe‑service control valves.

Floauto’s M series labyrinth control valves feature independently developed multi-stage pressure drop and anti-cavitation technology, providing up to 60 stages of pressure reduction. Combined with the self-compensating sealing function of floating seats, this design ingeniously reduces the friction torque between the ball core and the seat body, reinforcing absolute stability and an extended service life even under complex conditions of high-speed fluid erosion and ultra-high differential pressure. Furthermore, Floauto’s product series comes standard with powerful, high-thrust pneumatic cylinder actuators. Compared to the film-type actuators commonly used in the market, they offer extremely high rigidity thresholds, exceptional sensitivity, and ultra-fast response speeds. Additionally, our proprietary self-centering snap-in seat technology (threadless connection) represents a major advancement in maintenance simplification. It completely resolves the issue of traditional threaded seats seizing up under high-pressure conditions, which makes repair and replacement extremely difficult. By automatically calibrating the concentricity between the valve core and seat, this technology not only simplifies components and improves replacement efficiency but also significantly enhances the sealing performance and long-term operational reliability of the entire valve assembly.

The V6000 high-performance control ball valve is an independently developed and designed product by our company, featuring multiple national authorized utility model patents. Engineered specifically for high-temperature and high-pressure conditions, it incorporates an anti-clogging structure to prevent the accumulation and jamming of particulate media, as well as a rapid pressure relief mechanism for high-pressure scenarios. Compared with similar domestic and international products, it features significant functional and structural improvements. Its series-based design effectively solves complex application challenges across a broad range of operating conditions. Key advantages include high flow capacity, a wide adjustable range, reliable safety, and rapid opening/closing. Offering a superior cost-performance ratio over comparable global products, the V6000 resolves common issues with existing valves, such as difficulty in reopening after closure, poor resealing, short service life, and inadequate corrosion resistance. It is particularly well-suited for severe conditions involving multi-particulate and dirty media, which often severely restrict continuous industrial production. To withstand the erosion caused by high-temperature, high-pressure, and dirty media, the internal components feature advanced surface hardening treatments that easily meet stringent design requirements. Through a specially designed ball valve flow channel and superior surface hardening of the ball and seat, the valve utilizes HVOF (High-Velocity Oxygen Fuel) thermal spray technology to create an ultra-hard sealing surface. Combined with a constant-load graphite packing and a double-disc spring bi-directional sealing structure, it significantly reduces media pressure energy and enhances impact resistance. These innovations drastically extend the valve's service life, ensuring smooth and reliable operation of the user's system.

Relying on its completely independent mathematical modeling system, Floauto has successfully developed the V8000 series all-metal hard-sealed triple eccentric butterfly valve. Compared with similar multi-layer structure butterfly valves in the industry, this product boasts the most outstanding differentiated advantages: throughout the entire opening and closing stroke, the valve disc and seat only experience slight contact friction at the moment of complete closure (whereas most butterfly valves experience strong friction throughout the entire stroke). This significantly reduces the torque. As a result, it not only achieves ANSI CL VI tight hard sealing across all sizes, but also completely eliminates the degradation of trim life caused by mutual wear between the disc and seat. This makes it perfectly suitable for small opening micro-flow control conditions, a scenario that the butterfly valve industry generally avoids.

Floauto’s robust product performance and formidable technical capabilities have been rigorously validated in major national projects, serving as a strong testament to our core competitiveness. Our flagship products—the M series labyrinth control valves, the V6000 series high-performance control ball valves, and the V8000 series high-performance triple eccentric control butterfly valves—are now widely deployed across China's core oil and gas energy bases, including PetroChina, Sinopec, Xinjiang Oilfield, Tarim Oilfield, and Southwest Oil & Gas Field. Extensively utilized in critical safety applications such as compressor stations, pig launcher/receiver stations, and high-pressure dehydration separators, these products have successfully replaced imported equipment on a large scale, thoroughly resolving persistent operational issues like severe media erosion, intense equipment vibration, and pipeline damage caused by extreme temperatures. Furthermore, our products demonstrate exceptional versatility and stability in extreme conditions across the new energy and high-end chemical sectors. From the -196℃ ultra-low temperature storage and transportation in LNG applications, to ultra-high temperature cracking reactors in ethylene and polysilicon production, and high-load scenarios like high-pressure reinjection, Floauto’s complete range of severe-service valves maintain stable operation, verifying the reliability of domestically manufactured valves and providing solid equipment support for industrial development. Backed by a senior team of R&D and engineering service experts, we possess powerful capabilities in customized retrofits and resolving complex technical challenges. Leveraging our proprietary labyrinth throttling technology and floating seal control core technology, we provide exclusive customized upgrade solutions to efficiently modernize aging equipment and address issues such as poor adaptability of oversized imported valves or the clogging and instability of conventional control valves. This approach not only completely eliminates core operational pain points but also significantly reduces the high costs associated with importing and maintaining premium equipment, ultimately empowering industrial enterprises to cut costs, increase efficiency, and upgrade to domestically produced equipment, continuously enhancing technological autonomy and core competitiveness in severe-service fluid control.
