All valves are furnished with material certificate (EN 10204 3.1) and inspection records.
“We replaced our previous European swing check supplier with Thriveon. Lead time dropped from 14 weeks to 4 weeks, and cost per valve reduced by 38%. The RTFE seat seals perfectly even after 10,000 cycles.”
“Thriveon’s team helped us customise a 12″ flanged swing check with extended yoke for offshore service. All certificates arrived ahead of schedule – no non‑compliance issues during audit.”
“The DDP service to Long Beach was flawless. No surprise duties, valves had proper US‑standard markings, and the hydrotest reports were signed off by our inspector.”
Standard size (2″–12″) in WCB material ships in 15–20 working days. Larger sizes or special alloys (CF8M, duplex) need 25–30 days. We offer split‑shipment for urgent needs – contact us for expedite options.
Yes. We regularly supply NACE MR0175 / ISO 15156 compliant valves for sour service. Materials (WCB, SS316, Inconel overlay), hardness control, and certificate included. Please specify at enquiry.
Each shipment includes: material certificate (EN 10204 3.1), pressure test report, dimensional check report, and certificate of conformance. Additional 3rd‑party inspection (SGS, BV, Lloyds) can be arranged at extra cost.
Swing check valves have a hinged disc that swings open with forward flow – ideal for low pressure drop and horizontal or vertical upward flow. Lift check valves use a piston/ball lifted by flow, better suited for high‑velocity and smaller lines.
Yes. For new customers with a credible project, we provide one free sample valve (2″–4″) with the condition that the buyer covers shipping. After order confirmation, the sample cost is deducted from the first commercial order.
Standard: 30% T/T deposit, 70% before shipment. For long‑standing clients, we offer LC at sight or net‑30 after credit check. PayPal and credit card (4% fee) also accepted for smaller amounts.
Our engineering team offers free sizing and material selection. Provide your pressure, temperature, media, and pipe schedule – we’ll recommend the optimal valve and even send a 3D drawing for verification.
“We ordered 200 pieces of 8″ Class 150 swing checks for a water treatment plant in Arizona. Every valve arrived perfectly coated, with proper flange drilling per ASME B16.5. No leaks during commissioning. Highly recommended.”
“Thriveon’s quality control is on par with Italian brands we used before, but at half the price. They even updated the disc pin design to reduce wear – proactive engineering support.”
“I had a tight deadline for a shutdown. Thriveon managed to produce 16 valves in 18 days and airfreight them to Houston. Saved our schedule.”
