An undersized foot valve creates excessive friction loss, forcing pumps to work harder. Industry data shows a ¼” mismatch can increase energy consumption by up to 30%.
Wrong dimensions mean returns, re-ordering, and project delays. US buyers report an average of 8–12 days lost per incorrect valve shipment.
Oversized or heavy cast-iron foot valves inflate freight charges. With steel tariffs fluctuating, every extra pound hits your EBITDA.
Standard rubber seals fail in oil, chemicals, or high-solids water. Result: leaking, cavitation, and emergency replacements — at 3× the original part cost.
Global suppliers use inch vs. metric, different flange drilling templates, and varying seat heights. Without a reliable foot valve size chart, cross-referencing becomes a nightmare.
“In stock” often means 6+ weeks from China. Thriveon’s factory carries 2,000+ units of popular dimensions ready for container shipping within 10 days.
Below is our engineering-grade foot valve size chart covering flanged, threaded, and grooved end connections. All dimensions comply with ASME B16.1 / B16.5 standards and are 100% interchangeable with leading US brands.
| Size (in) | DN (mm) | L (in) | H (in) | Flange OD (in) | Bolt Circle (in) | No. of Bolts | Weight (lb) |
|---|---|---|---|---|---|---|---|
| 2" | 50 | 7.0 | 5.5 | 6.0 | 4.75 | 4 | 9.5 |
| 2½" | 65 | 7.5 | 6.0 | 7.0 | 5.50 | 4 | 12.2 |

A Texas utility replaced 34 undersized foot valves with Thriveon 6" flanged models. Result: 22% energy savings and zero seal failures in 14 months.
An Ohio chemical plant standardized on our 4" stainless steel foot valves — eliminating cavitation and reducing pump repair costs by $11k/year.
Wyoming oilfield operator uses Thriveon 3" ductile iron valves with NBR seals. After 2 years, zero leaks even with 10% H₂S content.
Measure the pipe ID or flange OD and the face-to-face length. For flanged valves, use the bolt circle diameter and number of bolts. Our foot valve size chart above includes all key dimensions — or you can email us a photo and we’ll match it within 4 hours.
A foot valve is a type of check valve installed at the bottom of a pump suction line. It keeps the pump primed by preventing backflow. Unlike an in-line check valve, a foot valve includes a built-in strainer to protect the pump from debris.
Absolutely. Thriveon supports OEM/ODM drilling patterns per ANSI B16.5, DIN, JIS, or your own drawing. Minimum order quantity for custom flanges is 50 units; lead time: 3 weeks from approval.
We stock cast iron (ASTM A126), ductile iron (ASTM A536), and stainless steel 316 (ASTM A351 CF8M). Seat seals: EPDM (standard for water), NBR (oil), or Viton® (chemical). Contact us for duplex or super duplex options.
We ship via FOB Tianjin or CIF US Port (Los Angeles, Houston, Savannah). Ocean freight takes 18–25 days. Stock items leave our factory within 10 days after PO confirmation, so total door-to-door time is typically 28–35 days.
For first orders we require 30% T/T deposit, 70% against copy of B/L. For repeat customers with good credit, Letter of Credit (L/C at sight) or net 30 days may be arranged. We accept USD payments.
Yes. Free samples are available for qualified buyers (you pay shipping). We’ll send a 2" or 3" flanged foot valve with your choice of seal. Use it for testing, then place a bulk order — we refund the sample cost on the first container.
All Thriveon foot valves come with a 24-month warranty against manufacturing defects. Our technical support engineers respond within 2 hours via WhatsApp or email. We also provide free replacement parts for any out-of-warranty issues.

"Switching to Thriveon cut our valve procurement cost by 31%. The quality is consistent, and their team always picks up the phone when we need technical help. Highly recommend."
"We’ve been burned by cheap Chinese valves before. Thriveon is different — they have real engineers, the documentation is professional, and the foot valve dimensions match exactly what we need. Trust built."
"Three months into a pilot with 6" stainless steel foot valves. Zero corrosion, zero callbacks. I just placed my first container order — that says everything."
"Thriveon’s technical data sheet is the best I’ve seen from a Chinese supplier. They provide actual test reports per batch, and the foot valve size chart makes ordering error-free. We’re planning a plant visit."
Limited-time offer: First-time US buyers receive a free 2" flanged foot valve sample (pay only shipping). Plus, lock in 2026 pricing for orders placed before April 30, 2026.
