Every pound of valve weight directly impacts your freight cost, structural load, and installation labor. Yet most suppliers hide weight data or provide only approximate figures — leading to budget overruns and project delays.
You need verified, standardized flanged ball valve weights from a factory that understands international logistics and engineering precision.
Below are the standard weights for full-port, flanged ball valves in WCB (carbon steel) and CF8M (316 stainless steel). Actual weight may vary ±3% depending on trim and manufacturer. Thriveon Valve provides certified weight certificates with every shipment.
| DN (mm) | NPS (inch) | WCB (kg) | CF8M (kg) | Face-to-Face (mm) |
|---|---|---|---|---|
| 15 | ½″ | 1.8 | 2.1 | 108 |
| 20 | ¾″ | 2.5 | 2.9 | 117 |

We don’t just sell valves — we provide certified weight data, optimized logistics, and engineering support so you can plan with confidence.
📌 Case Study – Texas Refinery, USA
A major refinery replaced 47 flanged ball valves (2″–12″ Class 300) across three processing units. The original supplier’s weight data was off by 9–14%, causing rework of pipe supports. Thriveon provided certified weights within 24 hours of inquiry, and the project completed 11 days ahead of schedule. Total logistics cost reduced by $8,400 vs. the initial plan.

Differences in casting wall thickness, flange dimensions (ASME vs. EN), trim configuration, and material grade all affect weight. Thriveon follows ASME B16.34 and B16.5 precisely, and we provide actual measured weight — not nominal weight — for each valve.
Submit your DN, pressure class, and body material. Our engineering team will generate a 3D model and deliver a calculated weight within 48 hours. Free of charge for OEM inquiries. Request now →
Base weights above are for bare-stem flanged ball valves (without actuator). For actuated valves, we provide combined weight data. Typical actuator adds 5–35 kg depending on size and torque.
Standard tolerance is ±3% for cast valves. For investment-cast or forged valves, tolerance is ±1.5%. Every valve is weighed individually before packing.
Yes — we issue a weight certificate per valve and per crate, with total container weight calculation. Many USA and EU customers use this data to avoid over-weight container penalties.
We provide free samples for qualified OEM/ODM projects up to DN50. You only pay shipping. The sample includes a full weight and dimensional report. Apply for sample →
Class 300 valves have thicker flanges and walls. Typically, a Class 300 valve weighs 35–50% more than the same DN in Class 150. Our chart above gives you comparative data for quick estimation.
We accept T/T, L/C, (and sometimes D/P for established accounts). Shipping: FOB Tianjin, CIF to major ports (Houston, Rotterdam, Jeddah, Durban). Delivery 7–25 days depending on size and quantity.
“Accurate weight data made our container loading plan perfect. No last-minute freight changes.”
“Six months using Thriveon flanged ball valves — zero failures, weights matched certificates exactly. Strongly recommend.”
“We compared weights from three Chinese suppliers. Thriveon’s data was the most consistent and closest to our own measurements.”
“Thriveon helped me specify the correct valves for a skid project. The weight data allowed precise structural design — saved us ~$3,200 per skid.”
“Fast response, honest weights, and excellent packaging. Our logistics team loves working with Thriveon.”

“Thriveon’s weight data allowed us to optimize container loading for a 24″ Class 150 order. We saved 22% on ocean freight compared to our previous supplier. The valves performed flawlessly during hydrotest.”
“We switched to Thriveon because they provided certified weight certificates for every single valve — not just a brochure value. That level of transparency is rare.”
