Eliminate water hammer, reduce maintenance downtime, and cut procurement costs by up to 30% with API-certified, non-slam dual plate check valves engineered for North American pipelines.
β 100% pressure tested | β ISO 9001 & API 594 | β 30β45 day delivery to USA
Low-cost valves from unverified sources often fail within 12 months. The resulting unplanned downtime, environmental cleanup, and emergency replacement can cost 5β10x the initial purchase price.
Standard brokers quote 10β14 weeks. When projects are delayed, every week over schedule eats into your margins. Time is money, especially on large EPC contracts.
Getting the wrong material grade (e.g., CF8 vs CF8M) or incorrect face-to-face dimensions causes costly rework. Language barriers and time zone delays make quick fixes impossible.
US projects require full traceability: material certificates, PMI test reports, and API 6D compliance. Without proper documentation, your valves may be rejected at the job site.
As a vertically integrated Chinese manufacturer with over a decade of North American export experience, Ningjin Thriveon Valve Co., Ltd. delivers top-tier dual wafer check valves (dual plate check valves) that solve the most common procurement headaches.
Eliminate 2β3 layers of middlemen. Get 15β30% cost savings and direct access to our engineering team. We control the entire production timeline.
Our wafer check valves are manufactured to API 594, API 6D, and ASME B16.34. 100% hydrostatic and pneumatic testing on every unit. Full material traceability included.
Standard lead time: 30β45 days to major US ports (Los Angeles, Houston, New York). Express air freight available for urgent maintenance needs (5β7 days).

βThriveon has been our go-to supplier for dual wafer check valves for 3 years. Their quality consistency is excellent, and their lead times are always shorter than promised. A true strategic partner.β
β Mark S. , Senior Procurement Manager, Texas Energy Corp

A dual wafer check valve (dual plate check valve) uses two spring-loaded plates that fold open with forward flow and close instantly when flow reverses. This design has a much shorter face-to-face, lower pressure drop, and eliminates water hammer. In contrast, a swing check valve relies on a heavy disc that swings fully open, taking up more space and closing slowly, which can cause damaging surges.
For standard water and wastewater, a WCB body with SS 316 plates and EPDM seat is the most cost-effective choice. For corrosive or brackish water, we recommend CF8M (SS 316) body with Super Duplex springs and Viton seals. We always provide a detailed material recommendation based on your specific media and pressure.
Our standard lead time for stock materials (WCB/SS 316, Class 150/300) is 30β45 days to US ports (Los Angeles, Houston, New York). For specialized alloys or high-pressure classes (Class 600+), typical lead time is 45β60 days. We also offer express air freight for urgent orders, delivering in 5β7 working days.
Absolutely. We offer full OEM and white-labeling services. We can apply your logo, brand color, custom tags, and specific packaging requirements. Our engineering team will also sign off on your dimensional and material specifications. Minimum quantity for OEM starts from 50 units per size.
Simply click here to fill out our inquiry form or email info@thriveonvalve.com. We typically respond within 4 hours. We provide free samples for qualified projects (buyer pays shipping, which is refundable on first order).
We ship FOB, CIF, or DDP (delivered duty paid) to any US address. Payment terms are flexible: T/T, L/C, and sometimes net 30 after credit evaluation. Our CIF prices to major US ports are very competitive because we ship high volumes and have contracted freight rates with major carriers.

"We switched to Thriveon's dual wafer check valves for our pump stations. The price was 22% lower than our previous supplier, and the delivery was 3 weeks earlier. The non-slam performance is excellent."
Michael D. β Plant Manager, Florida Water District
"I was skeptical about importing direct from China, but Thriveon changed my mind. Their technical documentation (API 6D, material certs) is flawless. Our inspector in Houston approved everything on the first try."
Jennifer R. β Project Engineer, PetroChem Inc., Alberta
"Fastest lead time I've ever experienced for 12" dual plate check valves. The customer service is outstanding β Alex and his team respond within hours, not days. We've found a long-term partner."
Robert K. β Supply Chain Manager, Midwest Mechanical
"We needed custom springs for a high-temperature steam application. Thriveon's engineers recommended Inconel X-750 and the valves have been performing perfectly for 18 months. Highly recommend."
David H. β Operations Director, California Refinery
