Every minute without a certified sprinkler backflow valve exposes your facility to:
You need a partner who eliminates these risks — not just a supplier.
Our backflow prevention valves combine North China's strongest supply chain with precision engineering. Each unit is designed to last 10+ years in the toughest commercial environments.
Custom flange drilling, stem lengths, and coating (epoxy, nylon, Rilsan) to match your existing systems. We designed over 200 custom backflow assemblies in 2025 alone.
Stocking program for standard sizes: 7-15 days from Ningjin port (vs industry average 35 days). Air freight available for urgent orders.
Direct factory pricing eliminates distributor margins. Example: 2-inch RPZ backflow valve — $187/unit (FOB Tianjin) vs US market average $298.
Every valve ships with ISO 9001, CE, RoHS, and NSF/ANSI 61 certifications. CCC and UL available upon request.
All units undergo 1.5x rated pressure hydrostatic testing and 10,000-cycle endurance check. Test reports included in every shipment.
Meets AWWA C510, ASSE 1013, and US EPA cross-connection regulations. Your inspectors will find zero issues.

For most commercial systems, a Reduced Pressure Zone (RPZ) valve is required by code (ASSE 1013) when there is a high health hazard. Pressure Vacuum Breakers (PVB) work for low-hazard applications. Our engineering team can review your site specs and recommend the correct assembly within 4 hours.
Standard sea freight (Tianjin to Los Angeles) takes 18-22 days. We maintain a stock of 10,000+ units for immediate loading. Express air freight delivers to your door in 5-7 days. Please note: customs clearance adds 2-4 days on average.
