Procurement managers and plant engineers tell us the same story: unreliable float valves lead to costly downtime, tank overflows, and unexpected maintenance. Here are the most common frustrations buyers face when sourcing float valve flange type solutions for their facilities.
If any of these sound familiar, you're not alone. The right float valve flange type can eliminate these pain points — but only when it's engineered for your specific operating conditions.
At Ningjin Thriveon Valve Co., Ltd., we've spent over a decade perfecting our flanged ball float valve design for industrial water treatment, cooling towers, storage tanks, and process lines. Here's what makes our solution different.
ANSI B16.5 Class 150/300 flanges ensure leak-free installation and compatibility with your existing piping. No adapter needed.
316 stainless steel float & stem, with a ductile iron body coated in fusion-bonded epoxy. Suitable for fresh water, seawater, and mild chemical applications.
Adjustable float arm allows set-point accuracy within ±5 mm. Reliable automatic shut-off without chatter or vibration.
Standard sizes (DN50–DN300) ship in 7–15 days. OEM/ODM configurations in 20–25 days. Air freight available for urgent orders.
100% hydrostatic tested, with material certificates and dimension reports included. ISO 9001:2015 certified production.
Custom flange drilling, special float materials (PVC, brass, 304 SS), and extended stems for deep tanks. Your specs, our engineering.
All data below is based on our standard series. Custom configurations are available for volume orders.

Our industrial float valve with flanged connection is used across multiple sectors. Here are three typical scenarios where buyers saw immediate ROI.

🏭 Case 1 — Cooling Tower Make-Up Water (Texas, USA)
A petrochemical facility replaced their brass float valves with our DN80 316SS flange type. Result: overflow incidents dropped from 12/year to 0, saving ~$47,000 in water and chemical treatment costs annually.
🏭 Case 2 — Potable Water Storage Tank (Saudi Arabia)
A municipal contractor installed DN150 epoxy-coated ductile iron float valves across 18 tanks. The epoxy lining eliminated corrosion issues, and the adjustable float cut installation time by 40%.
🏭 Case 3 — Chemical Dosing Tank (South Africa)
A mining operation required a flanged ball float valve for a sulfuric acid dilution tank. Our CF8M (316) body with PTFE seal passed the 12-month acid resistance test with zero degradation.
A flanged float valve is a mechanically actuated valve that uses a buoyant float to control liquid level in a tank or reservoir. As the liquid rises, the float moves a lever that closes the valve, stopping the inflow. When the level drops, the float opens the valve again. The flanged end allows direct bolting to ANSI, DIN, or JIS pipe flanges for a secure, leak-tight connection.
Our standard range is manufactured to ANSI B16.5 Class 150 and Class 300. We also offer DIN PN10/PN16 and JIS 10K/20K on request. Custom flange drilling (bolt circle, number of holes) is available for OEM volume orders.
Yes. For temperatures up to 180°C (356°F), we recommend a 316 stainless steel float and stem combined with a ductile iron or CF8M body. For applications above 180°C, we can engineer an all-stainless configuration with extended stem and high-temp seals. Please share your operating parameters for a specific recommendation.
For standard sizes (DN50–DN300), production takes 7–15 working days. Shipping to the USA, Europe, or Middle East typically takes 12–20 days by sea (FOB Tianjin or CIF your port). Air freight is available in 5–7 days. We provide a full shipping cost breakdown before you confirm the order — no hidden fees.
Yes. For qualified buyers (companies with a verifiable business license or trade reference), we offer one free sample unit per model. You only pay the shipping cost. If the sample doesn't meet your performance expectations, we'll work with you to adjust the design or issue a full refund on the sample value.
Every valve undergoes 100% hydrostatic pressure testing at 1.5 times the working pressure. We also perform dimensional checks on flange bolt holes and sealing surfaces. Material certificates (EN 10204 3.1) are included with every shipment. You can request photos or video of the test before dispatch.
We accept T/T bank transfer (30% deposit, 70% before shipment), L/C at sight for large volumes, and PayPal for sample orders (value under USD 2,000). For first-time buyers, a 50% deposit is standard. Long-term contracts can negotiate open terms after 6 months of clean payment history.
Absolutely. We routinely produce extended stems (up to 2 meters) and custom float arm lengths. Our engineers can design a float valve flange type to match your exact tank geometry and liquid level set-point. Just send us your tank drawing or fill out our technical questionnaire.
