* All assemblies are 100% hydrostatically tested and shipped with a test report certificate. Third-party inspection (SGS, BV) is always welcome.
Thriveon valves are installed in critical infrastructure across the United States, Europe, and the Middle East. Our compliance and quality systems are validated by international regulatory bodies.
Real feedback from procurement managers, engineers, and contractors who rely on Thriveon for their backflow prevention needs.
"We switched to Thriveon for a 12-building multifamily project in Texas. The DCVAs passed inspection on the first try. Thriveon saved us 37% compared to the legacy brand we used before."
"The lead time was the game-changer for us. We got an 8-inch DCVA in 18 days. The quality rivals any US-made assembly. We are now standardizing Thriveon valves across our irrigation division."
"We were initially concerned about quality consistency from an overseas supplier. Thriveon invited our QC team to audit their factory. The transparency and engineering depth are world-class."
"Excellent product for the price. We use their double check valves for industrial cooling towers. DDP shipping made the import process seamless. Highly recommend for value-driven projects."
"The technical support from Thriveon's engineers is outstanding. They helped us customize the trim for a seawater application. The valves have been in service for 18 months with zero issues."
Quick answers to common procurement and technical questions. Designed to help you make an informed decision.
A double check valve assembly (DCVA) is a backflow prevention device consisting of two independently acting spring-loaded check valves. It is designed to prevent the reverse flow of non-potable water or contaminants into the potable water system under low-hazard conditions (e.g., irrigation, fire sprinkler systems). The two valves provide a redundant layer of protection. It works by closing automatically when flow reverses, sealing the line.
The main difference is the level of hazard they protect against. An RPZ device includes a differential relief valve and is used for "high hazard" applications (e.g., chemical plants, sewage treatment). A DCVA is for "low hazard" applications (e.g., irrigation, residential/commercial water lines). DCVAs are generally smaller, less expensive, and require less maintenance than RPZs. Always consult local codes (e.g., IPC, UPC) for specific requirements.
Most local plumbing codes in the US require annual testing of backflow preventers, including DCVAs. Testing must be performed by a certified backflow tester (ASSE or ABPA certified). Thriveon valves are designed with accessible test cocks to simplify the annual testing process.
Absolutely. Thriveon specializes in OEM/ODM customizations. We can adjust flanges (ANSI 125/150), offer grooved ends, provide NACE MR0175 compliance, apply custom paint (FDA approved epoxy), and add your company tag or UL listing markings. Minimum quantities are flexible for project-specific needs.
Standard sizes (2"–8" flanged) ship in 15–30 days after order confirmation. Larger sizes (10"–16") require 35–45 days. We ship via sea freight (FOB Tianjin or CIF/DDP to your nearest US port). Thanks to our lightweight ductile iron design, shipping costs are typically 20–30% lower than equivalent cast iron assemblies. Air freight is available for emergencies.
Yes. Our valves are manufactured in an ISO 9001:2015 certified facility. They are designed to meet ASSE 1015 and AWWA C510 standards. We can provide material and test certificates. For the Canadian market, we comply with CSA B64.5 requirements. NSF 61 certification for potable water contact is available upon request.
Yes! For new customers, we encourage a sample order to evaluate quality, fit, and finish. Sample MOQ is 1–2 units.
