Flexible wedge + hardened seat overlay. API 598 compliant zero-leakage test. Stem seal with double O-ring + graphite packing — no fugitive emissions.
Our factory in Hebei, China runs 6 dedicated lines. Standard lead time 4–6 weeks (vs. industry 10–14 weeks). Express shipping to US ports in 18 days.
Need a special end connection, extended bonnet, or cryogenic service? Our engineers (10+ years average experience) will design to your exact piping spec.
We provide DDP / CIF / FOB pricing with no hidden fees. Consolidation shipping reduces freight cost by up to 22% for mixed valve orders.

All valves are serialized, traceable, and supplied with material certificates per EN 10204 3.1.
"We replaced 18 standard-port gate valves with Thriveon's full bore design. Pump discharge pressure dropped 14% — saving $47,000/year in energy costs."
— Mark R., Piping Engineer Chevron, Houston, TX"Thriveon delivered 46 full bore gate valves in 5.5 weeks — 6 weeks faster than our previous supplier. Installation was seamless, zero leaks on hydrotest."
— Abdullah S., Procurement Manager Sabic, Jubail, KSA"After 3 years in a corrosive slurry service, the wedge still operates smoothly. The full bore design eliminated the plugging we had with other brands."

A full bore gate valve (also called full port gate valve) has an internal diameter equal to the inside diameter of the connecting pipe. This means the valve creates no flow restriction when fully open — the media passes through as if the valve were not there. This is critical for pigging operations, viscous fluids, and applications where pressure drop must be minimized.
If your system requires unrestricted flow, pigging capability, low pressure drop, or handles slurries/viscous media — choose full bore. If weight, cost, or space is extremely constrained and the media is clean, a reduced bore may be acceptable. However, for most industrial isolation services, full bore is the safer, more efficient choice.
Yes. We regularly supply full bore gate valves for steam service up to 650°C using WC9 or alloy steel bodies with Stellite overlays. Extended bonnets, high-temperature packing, and flexible wedge designs are available. Share your operating conditions and we will recommend the optimal trim.
Standard sizes (2"–12", 150#–600#) ship in 4–6 weeks. Larger sizes or special alloys require 8–10 weeks. For urgent projects, we offer expedited production (3–4 weeks) with priority scheduling. Express air freight to US airports takes 5–7 days.
Every full bore gate valve is manufactured to API 600 / API 602 and tested per API 598. We provide material certificates, NDE reports (RT/MT/PT/UT), and a 5-year warranty against manufacturing defects. Third-party inspection (SGS, BV, Lloyds) is welcome at no extra coordination cost.
Absolutely. We have extensive OEM/ODM experience supplying valve brands and distributors in the US and Europe. We can match your existing pattern, apply your brand name, and meet your specific marking and packaging requirements. Minimum order quantity: 20 pcs for standard sizes.
We accept T/T (30% deposit, 70% before shipment), L/C (irrevocable), and for established customers, we can discuss open terms. All pricing is quoted FOB Tianjin / CIF US Gulf Port / DDP door-to-door depending on your preference.
Free samples are available for qualified buyers (you pay shipping). We can supply a single 2" full bore gate valve for testing. Contact our team at info@thriveonvalve.com with your requirements to arrange a trial.
"We ordered 24 units of 8" Class 300 full bore gate valves for a wastewater treatment upgrade in Ohio. The quality matched our existing US-made valves but at a 37% lower cost. Delivery was 5.5 weeks — our client was impressed. We've made Thriveon our preferred valve vendor for all upcoming projects."
"Thriveon's full bore gate valve was a direct replacement for a valve that kept clogging in our polymer transfer line. The full port design solved the problem immediately. We've had zero blockages in 14 months of operation. Their engineer helped us select the correct trim — great technical support."
"I was skeptical about importing valves from China, but Thriveon changed my mind. The documentation was perfect — full traceability, certified material reports, and the valves passed our shell test with zero defects. Shipping to Johannesburg took 22 days. Will definitely order again."
"We've been using Thriveon full bore gate valves on our fire water mains for 3 years. All 58 valves are still operating smoothly — no leakage, no stem galling, no issues. The epoxy coating applied was thick and uniform. I recommend them to any specifier looking for reliable fire protection valves."
"Thriveon's full bore gate valve is now standard spec on all our raw water intake projects. The price-to-performance ratio is unmatched. Their sales team answered all my technical questions about pressure class and facing dimensions within hours. 5 out of 5 stars for service and product."
