Certifications & Compliance:
ISO 9001:2015 CE (PED 2014/68/EU) RoHS API 598 Tested NACE MR0175 (on request) ATEX (on request) FDA / HACCP (on request)A wafer check valve is compact and sandwiches between two flanges, while a flanged check valve has integral flanges that bolt directly to the pipe. The wafer style is lighter, lower cost, and ideal for space-constrained installations. Thriveon's wafer check valve flanged version combines the compact body with full flange adapters for easy retrofit.
Yes. Our Class 600 and Class 900 wafer check valves with flanged ends are suitable for saturated steam up to 450°C. We use SS316 discs and spring-loaded designs to prevent chatter. Request a steam application data sheet for your pressure/temperature conditions.
Standard production is 18 working days for sizes DN50–DN300. Add 7–10 days for sea freight to US West Coast ports. Express air freight is available (3–5 days) for emergency orders. We provide a real-time shipping tracker for every order.
Absolutely. We manufacture OEM/ODM valves with your brand, laser engraving, and custom packaging. Minimum order quantity is 50 units for standard sizes. We also supply white-label valves for distributors in the USA and Europe.
We accept T/T (30% deposit / 70% before shipment), L/C at sight, and credit card (for samples). For established buyers, we can discuss open terms after the first 3 orders. All payments are secured via our bank (China Merchants Bank).
Every valve undergoes 100% shell hydrostatic test, seat leakage test, and backflow test per API 598. Material certificates (EN 10204 3.1) are included. We also offer third-party inspection (SGS, BV, TÜV) at your cost.
We offer a 12-month warranty against manufacturing defects from the date of shipment. For any quality issues, we replace the valves at our cost or issue a credit. Our English-speaking technical team is available via WhatsApp +86-311-86935302 or email during business hours (UTC+8).
"Thriveon's wafer check valve flanged saved our project. We were on a tight deadline and they delivered in 16 days. The valve fit perfectly on our ASME B16.5 flanges. No leaks, no hassle."
"I've sourced valves from China for 12 years. Thriveon is the first supplier who actually answers technical questions in detail. Their engineer recommended a duplex 2205 body for our sour gas application — saved us from a costly failure."
"Good quality for the price. The flange thickness was consistent across all 200 units. We used them on a municipal water project in Durban. Would buy again."
"The OEM service is excellent. They put our brand on the valves and created custom packaging. Lead time was exactly as promised. We're now a regular distributor."
"I needed a Class 150 wafer check valve with EPDM seat for a desalination plant. Thriveon had the best price and fastest delivery. The valves have been running 24/7 for 6 months with zero issues."
Limited-time: free sample valve (DN50) for qualified buyers — test our quality risk-free.
