About Us

Pureflow Sanitary Valve Co.,Ltd is a leading global provider of precision hygienic flow control solutions and one of China’s most powerful manufacturers of fluid control sanitary equipment. Since 1988, we have leveraged decades of innovative valve technology expertise to become a trusted partner for businesses needing sterile, efficient, and regulatory-compliant fluid management systems.

Our core product portfolio covers a comprehensive range of sanitary equipment:

• Valves: Manual/pneumatic/electric ball, diaphragm, reversing, control, relief, mixproof, special valves, and butterfly valves (including standard forged, integrated block, and 2-way diaphragm valves that set industry performance benchmarks).
• Pumps: Open impeller centrifugal pumps, enclosed pumps, rotating piston (rotary) pumps, mixing (blender) pumps, and dedicated pumps.
• Liquid storage equipment: Manholes, cleaning balls, sanitary respirators, liquid indicators, sight glasses, filters, and sampling valves.
• Plumbing fittings: Couplings, tri-clamp couplings, welded/clamped/threaded elbows, tees, reducers, and various pipeline connectors.

Every Pureflow product is crafted from premium 304，316L stainless steel and FDA-approved elastomers, featuring crevice-free surfaces, streamlined flow paths, and a minimum internal surface finish of Ra ≤ 0.8 µm for optimal cleanability and drainability. Key design advantages include valve cap isolation (separating operational components from process fluids), automatic shut-off via elastomeric diaphragm beads, and tool-less maintenance that reduces downtime by up to 90%. Fully customizable solutions—from materials to flow paths—are available for complex processing needs.

We operate state-of-the-art production facilities equipped with advanced LG Mazak CNC machining centers, cut-off machines, and various automatic production equipment. Our inspection capabilities are equally robust, including X-ray fluorescence analyzers, metal analyzers, inner surface detectors, roughness analyzers, and automatic valve leak testing machines—ensuring rigorous quality control at every stage.

Compliance is central to our operations. All products hold authoritative certifications: ISO9001-2008, PED, 97/13/EC, 3A, and China’s State Sanitary License. They fully comply with international standards (DIN, SMS, IDF, ISO, BS, DS, RJT, BPE) and meet GMP (China), FDA (US), and PED/97/23/EC (Europe) requirements, with approvals in Europe, America, and other global markets. This ensures seamless integration into sterile processes such as pharmaceutical production, bioprocessing, food and beverage manufacturing, and fine chemical processing.

We serve global clients across Europe, the Americas, Asia-Pacific, the Middle East, and Africa, partnering with leaders in biopharmaceuticals, dairy, craft brewing, cosmetics, and specialty chemicals. Beyond product delivery, our experienced engineers provide end-to-end support: technical consultation, custom design, after-sales service, and maintenance training. We build long-term collaborations based on transparency, responsiveness, and operational excellence.

At Pureflow, we stand by the philosophy "Every Drop Matters." We integrate environmental responsibility into manufacturing—optimizing energy use and materials while developing waste-minimizing products. Combining industry expertise with innovation, we invest in R&D to advance fluid control technology, focusing on smart control integration, enhanced durability, and lower total ownership costs.
