Engineered for industrial media, water treatment, and oil & gas lines. Full port design eliminates flow restriction – direct factory pricing for procurement managers, technical directors, and supply chain leaders.
Every procurement manager knows that a reduced‑port valve saves a few dollars upfront. But in heavy‑duty lines, that small saving often leads to:
A standard‑port 28 mm valve can reduce flow by up to 40 %, forcing pumps to work harder. Over a year, that adds 18–25 % to energy costs.
Low‑cost valves often use thin wall castings and poor‑quality PTFE seats. End users report 3× more leak incidents within 12 months.
Many suppliers quote low prices but add 15–20 % surcharges for smaller orders or non‑standard materials. Total landed cost can exceed a premium valve.
Valves without full ISO 9001/CE certification often fail site inspection. One Fortune 500 buyer told us they lost $47 000 in labor due to a non‑compliant batch.

What does “full bore” mean for a 28 mm ball valve?
Full bore (or full port) means the ball’s internal diameter equals the pipe’s inner diameter – in this case 28 mm. There is no flow restriction, unlike standard‑port valves where the bore is one size smaller. This eliminates pressure drop, cavitation, and energy waste.
What is the price of a full bore lever ball valve 28mm from Thriveon?
Pricing depends on material (304 vs. 316 vs. carbon steel), seat type, and quantity. As a reference, FOB price for a 304/PTFE version starts at US $8.50/pc for MOQ 50 pcs. Contact our sales team for a precise quote with all incoterms.
Can I get a custom handle or locking device for this valve?
Yes. We offer OEM/ODM customization: padlockable handles, T‑handles, extended stems, color‑coded grips, stainless steel or carbon steel handles. Minimum order for custom handles is 100 pcs; lead time adds 3–5 days.
What certifications do you provide for the 28 mm ball valve?
Standard: ISO 9001, CE/PED 2014/68/EU, RoHS, API 598 test certificate. Optional: WRAS (UK water), FDA 21 CFR 177 (food contact), ATEX (for explosive atmospheres), and NACE MR0103. We include material traceability and pressure test reports with every order.
How long does shipping take to the USA?
Standard production + sea freight: 25–35 days (FOB Tianjin to Los Angeles / Houston). Air freight available in 7–10 days. We also offer EXW for buyers with their own forwarder. Rush orders (partial shipment) can ship in 12 days.
What is your return/warranty policy?
We offer 18‑month warranty against manufacturing defects. If a valve fails under proper use, we replace it free of charge (excl. shipping). For approved buyers, we provide free samples to test before bulk order. Full money‑back guarantee on first order if not satisfied.
Can you supply the 28 mm full bore valve with NPT threads?
Absolutely. We offer BSP (parallel) and NPT (tapered) threads as standard, as well as socket weld, butt weld, and tri‑clamp. Just specify your connection type when requesting a quote.
