A gate valve is essential for full-bore, bi-directional shut-off in water supply, HVAC, fire protection, and industrial pipeline systems. At Zhejiang Haoji Fluid Technology Co., Ltd., we design and manufacture premium gate valves that deliver leak-tight performance, long service life, and global compliance.
Located in Yuhuan City—known as “China’s Valve Capital”—our 30,000+ sqm factory produces a wide range of gate valves, including:
- Brass Gate Valve (for residential and commercial plumbing)
- Stainless Steel Gate Valve (corrosion-resistant, ideal for food, pharma, and marine use)
- Cast Steel Gate Valve (for high-pressure industrial applications)
- Flanged Gate Valve (compatible with ANSI, DIN, JIS standards)
- Soft Sealing Gate Valve (EPDM/NBR seat for zero leakage in clean water)
- Hard Seal Gate Valve (metal-to-metal seal for steam, oil, or abrasive media)
- Rising Stem and Non-Rising Stem designs to suit above-ground or buried installations
Every gate valve undergoes rigorous testing in our in-house international-standard laboratory. We use precision casting and CNC machining equipment imported from Germany, Italy, and Taiwan to ensure micron-level accuracy and smooth operation.
Our gate valves are certified under:
- ISO 9001:2015 (Quality Management)
- ISO 14001:2015 (Environmental Management)
- EU CE Marking
- France ACS (for potable water safety)
- Germany DAkkS-accredited testing
- CQC, BSCI, TS Certification
