Gate Valves: How to Source Reliable Products from China in 2025
As global demand for industrial valves grows, China remains the top manufacturing hub for gate valves used in oil, gas, water treatment, and chemical processing. This guide helps buyers navigate the Chinese market with confidence.
How to Find Reliable Gate valves from China in 2025
1. Verify certifications: Look for ISO 9001, API 600, and CE marks from suppliers like Zhejiang Petrochemical Valve or Shanghai LV Valve.
2. Request material test reports: Reputable manufacturers provide ASTM A216 or A351 compliance documents.
3. Check production capacity - Top factories can produce 50,000+ valves/month with CNC machining centers.
What Buyers Should Know Before Buying Gate valves from China
- Lead times average 30-45 days for customized valves
- MOQs typically start at 50 pieces for standard sizes
- FOB prices are 30-50% lower than European/American brands
- Always request pressure test videos before payment
Types of Gate valves
1. Rising Stem: Visual operation status, ideal for above-ground installations
2. Non-Rising Stem: Space-saving design for underground use
3. Wedge Gate: Most common type with metal-to-metal sealing
4. Knife Gate: For slurry/solid media with wafer-style bodies
Functions and features of Gate valves
- Full-port design minimizes flow restriction
- Stem protection with bellows seals in nuclear-grade valves
- Fire-safe models meet API 607 standards
- Cryogenic versions for LNG applications (-196°C)
