Providing High-Performance Trunnion-Mounted and Floating Ball Valves for Critical Global Infrastructure, Energy, and Industrial Processing.
Industry-standard solutions for high-pressure and extreme-temperature service.
As a leading China Float Ball Valve Supplier, we recognize that the industry is shifting from standard commodity valves to specialized, high-integrity isolation solutions. In the current global landscape, "float ball valve" refers not just to the traditional seating mechanism but to a critical component in complex flow control architectures.
The demand for LNG-ready and Hydrogen-compatible valves is surging. Modern suppliers must offer valves that minimize fugitive emissions (ISO 15848-1) to meet ESG targets.
Global EPCs are moving away from "lowest price" to "lowest Total Cost of Ownership (TCO)." This emphasizes material traceability and 30+ year lifecycle reliability.
Integrated pipeline safety systems now require Double Block and Bleed (DBB) capabilities in compact footprints to reduce weight on offshore platforms.
Engineering the next generation of flow control technology.
Current R&D is focused on advanced cladding technologies. By applying Inconel 625 or Stellite 6 overlays on the sealing surfaces of carbon steel bodies, we provide the corrosion resistance of high-alloy valves at a fraction of the cost. This is essential for sour gas (H2S) service and desalination projects.
Our floating ball valves utilize flexible seat designs that use the line pressure to assist in sealing. In high-pressure trunnion designs, we've implemented Double Piston Effect (DPE) seats that provide redundant sealing barriers, ensuring process safety even if one seat is damaged.
The "Smart Valve" era is here. We are integrating acoustic leakage sensors and torque monitoring into our automated valve packages. This allows for predictive maintenance, preventing costly unplanned shutdowns in petrochemical plants.
Hydrogen molecules are extremely small and can cause embrittlement in standard steels. Our roadmap includes the validation of specialized elastomers and 316L stainless steel internals designed specifically for high-pressure hydrogen storage and transport.
Full adoption of Low-Fugitive Emission packing across all lines.
Launch of Hydrogen-certified (SIL 3) isolation valves.
AI-driven predictive maintenance modules integrated into actuators.
SLVCN is not just a manufacturer; we are a partner in engineering safety. With a 10,000ใก facility and certifications spanning API 6D, CE/PED, and ISO 9001, we ensure every valve leaving our floor meets the "Zero-Leakage" standard.

High-integrity sealing to prevent leakage of volatile hydrogen gas under extreme storage pressures.
Expert insights on valve selection and maintenance.
In a floating ball valve, the ball is held by the seats and "floats" against the downstream seat under pressure to seal. In a trunnion valve, the ball is supported by a stem and a lower trunnion, making it more suitable for large diameters and high-pressure ratings where seat friction must be minimized.
Yes, all our critical service valves are designed and tested according to API 607 or API 6FA. This ensures that in the event of a fire, the metal-to-metal secondary seal maintains integrity after the primary soft seats are destroyed.
We use extended bonnets to keep the stem packing away from the cryogenic liquid, along with specialized PCTFE or Kel-F seats that maintain flexibility at -196โ.
Absolutely. We specialize in integrated Double Block and Bleed valves that combine two balls and a bleed valve into a single forged body, significantly reducing weight and leakage paths compared to traditional hook-ups.
