The result? A hidden tax on your productivity that many engineers don't fully quantify until it's too late.
Our full port butterfly valve (Model TFP-200 series) is designed with a precision-machined disc and a self-lubricating, blowout-proof stem. The defining feature: the bore diameter matches the inside diameter of the connecting pipe, delivering 100% full bore area with zero obstruction in the open position.
Full port area equal to Schedule 40 pipe ID. Achieves zero pressure drop across the valve. Ideal for high-flow and slurry applications.
Bi-directional sealing rated to ISO 5208 Rate A (zero visible leakage). Pressure-assisted seat design ensures a tight shut-off at both low and high pressures.
Direct mounting for pneumatic, electric, or hydraulic actuators. No brackets needed—saves installation time and reduces potential failure points.
Engineered for -20°C to 200°C. Available in EPDM, NBR, Viton™, and PTFE seats to handle water, oil, gas, chemicals, and steam.
Standard sizes (2"–12") ship in 15–25 days. OEM/ODM customizations in 4–6 weeks. Our Tianjin port location ensures fast, cost-effective shipping to Houston, Rotterdam, and Dubai.
Eliminate the middleman. Get ISO 9001:2015 quality at factory-direct prices. Third-party testing (Lloyd's, BV) available on request.
All dimensions conform to API 609 Category B and ASME B16.34. Wafer and lug styles available.

Data based on a 6" Class 150 valve in water service at 20 ft/s. Actual savings may vary based on system configuration.
Full port design minimizes friction losses in crude oil, produced water, and natural gas gathering lines. NACE MR0175 compliant materials available for sour service.
Prevent sediment buildup and maintain full flow capacity in water mains and sludge lines. EPDM lining provides excellent chemical resistance and long service life.
UL/FM listed options available. Full port ensures maximum flow to sprinklers and hydrants when every second counts. Zero obstruction reduces head loss across the system.
Optimize chilled water, hot water, and condenser loops. Reduced pumping costs provide an ROI that often pays for the valve upgrade in under 12 months.
Thriveon valves are specified by leading engineering firms and end users across five continents. Our commitment to powerful factory quality, on-time delivery, and OEM flexibility makes us the preferred partner for complex projects.

"We switched to Thriveon full port valves for our main water injection lines in West Texas. Within 30 days, pump discharge pressure dropped by 12%, which translated to over $40,000 in annual energy savings. The delivery was on time and the documentation was perfect for our AIChE audit."
"We were skeptical about importing full bore valves from China, but Thriveon changed our perspective. The ISO 9001 factory audit was flawless, and the third-party hydrostatic testing gave us total confidence. We ordered 800 units for our new desalination plant in Saudi Arabia."
"Thriveon's OEM team engineered a custom full port butterfly valve with a 254mm bore and PTFE seat for our chemical processing line. The precision machining was spot on, and the price was 35% lower than our previous European supplier. Lead time? Just 5 weeks. Outstanding."
"We use Thriveon full port valves on all our critical HVAC mains. The flow coefficient (Cv) matches their published data perfectly. No more oversized pumps or balancing issues. Thriveon has become our go-to for standard valve specifications."
"As a distributor in Houston, I need a manufacturer who can deliver consistent quality at competitive prices. Thriveon has been our most reliable Chinese supplier for 4 years. Their full port butterfly valves meet ANSI standards perfectly, and their logistics team always helps us consolidate freight to save cost."
A full port butterfly valve (also called a full bore butterfly valve) has an internal bore diameter equal to the inner diameter of the connecting pipe. This allows the pipeline to maintain its full cross-sectional area through the valve, resulting in minimal flow restriction and virtually zero pressure drop across the valve when fully open.
Standard full port dimensions match Schedule 40 pipe IDs. For example, a 6" full port butterfly valve has a 152.4 mm bore. Our full range covers 2" (50.8 mm) up to 12" (304.8 mm), with larger sizes available upon request. All dimensions comply with API 609 Category B. For exact measures, you can request our dimensional drawing (PDF/CAD) here.
By eliminating the area reduction found in standard port valves, a full bore design allows the fluid to pass through without accelerating or changing direction. This eliminates the energy losses associated with turbulence and velocity changes. The result is a pressure drop that is typically less than 0.5 PSI, compared to 3–5 PSI in a standard reduced-port valve under the same flow conditions.
While full port butterfly valves can be used for moderate throttling (typically 20° to 70° open), their primary design purpose is for full open/close isolation. For precise throttling control, we recommend a characterized disc design or a V-port butterfly valve. Consult with our engineering team to select the right valve for your control application.
Standard full port butterfly valves (2"–12") ship in 15–25 days. Custom OEM orders (special materials, coatings, actuation, or certifications) typically take 4–6 weeks. We work closely with our logistics partners to offer consolidated shipping options to reduce your freight costs, with regular monthly LCL containers to Houston, Rotterdam, and Jebel Ali.
Yes. Our full port butterfly valve is available in both wafer style (for general isolation between flanges) and lug style (allowing single-side flange removal for maintenance). Both styles are available in the same full bore configuration and pressure classes.
Absolutely. Our full port butterfly valves are designed, manufactured, and tested in accordance with API 609 Category B and API 598. Our factory is ISO 9001:2015 certified, and we offer additional third-party inspection by Lloyd's, BV, or SGS upon request. We provide full material traceability and test reports with every shipment.
