Engineered for water & wastewater, irrigation, and industrial process lines.
For purchasing managers and plant engineers who demand reliable prime retention, corrosion resistance, and cost-effective global logistics.
Pumps lose prime every 2-3 weeks, causing unscheduled downtime. In a 500 GPM system, each restart wastes 1,200+ gallons and 45 minutes of labor.
Standard cast iron foot valves fail within 6 months in brackish or chemically-dosed water. Replacement cost + lost production = $2,800+ per incident.
Oversized packaging from multiple suppliers inflates freight. One Fortune 500 buyer reported 37% of valve spend went to shipping and warehousing.
Incoming inspection rejects 8-12% of foot valves from budget sources – thread leaks, thin castings, stuck discs. Non-conformance penalties add $450 per rejected lot.
Custom-spec valves from traditional suppliers take 14-18 weeks. Meanwhile, your pipeline installation sits idle – $5,000/day in lost revenue for a mid-size plant.
Buying valves, screens, and gaskets separately doubles procurement overhead. One PO instead of three could save 6 hours of administrative work per order.
Precision-machined Buna-N or EPDM seal ensures <0.1% leakage at 150 PSI – pump prime is maintained even after 72 hours of standby.
Available in SS304, SS316, ductile iron with epoxy coating, and bronze. Independently tested to 1,000+ hours salt spray per ASTM B117.
Custom thread sizes (NPT/BSP), flange drilling, screen mesh, and pressure ratings. Our engineers deliver prototypes in 10-15 working days – not weeks.
We supply the complete inline foot valve assembly – body, disc, spring, screen, gasket – all from one QC line. Reduce your supplier count by 60%.
No middlemen. Our ductile iron inline foot valve (2", NPT) starts at $18.90/unit FOB Tianjin – 22% below market average for equivalent quality.
Dedicated freight consolidation for USA, Saudi Arabia, South Africa, and Italy. Full container or LCL – door-to-door tracking included.

6" ductile iron inline foot valves with 1/8" screen. Result: Pump prime held for 96+ hours, reduced maintenance calls by 60%. Annual savings: $14,500 per pivot.
SS316 4" foot valves with Viton® seals for GCC cooling towers. Result: Zero leakage after 18 months continuous operation in 55°C ambient.
8" flanged ductile iron with epoxy coating. Result: 30% lower head loss vs. competitor valves, pump energy consumption reduced by 11%.
An inline foot valve is a specialized check valve installed at the suction line of a pump. It features an integrated strainer/screen to prevent debris entry and a spring-assisted disc that seals tightly when the pump stops – maintaining prime. Unlike a standard check valve, a foot valve is designed for vertical or horizontal mounting directly in the pipe, with a built-in screen to protect the pump.
For clean water irrigation, ductile iron with epoxy coating offers the best cost-to-life ratio. For brackish water, chemicals, or high-chloride environments, choose SS316 or bronze. For food-grade or potable water, use SS304 or SS316 with FDA-compliant EPDM seals. Our sales engineers can help you match materials to your water chemistry – send us a sample analysis.
Absolutely. We offer OEM/ODM customization for NPT, BSP, BSPT, and flanged connections to ANSI 125/150/300, DIN, JIS, or your own drawing. Custom screen mesh sizes (1/32" to 1/2") are also available. Lead time for custom inline foot valves is typically 10-15 working days for samples.
Our standard MOQ is 50 units per size for stock items. For first-time buyers, we offer sample orders of 5-10 units at a 10% premium. Pricing for 2" ductile iron NPT inline foot valves starts at $18.90/unit FOB Tianjin. Volume discounts apply for orders above 500 units. We accept USD, T/T, L/C, and PayPal for sample orders.
We ship via ocean freight (FCL or LCL) and air express for urgent orders. Ocean freight to Los Angeles / Houston: 18-25 days. Air express (DHL/FedEx) to major US cities: 5-7 days. Shipping cost for a sample order of 10 units is approximately $85-120. For full container orders, we can arrange door-to-door with customs clearance.
Yes, we offer paid samples with full refund on your first bulk order. Sample cost is invoiced separately, and once you place a production order of 200+ units, the sample cost is deducted from the invoice. This allows you to verify fit, performance, and quality risk-free.

For Saudi Arabia, we can provide SASO certification upon request. We recommend sharing your local standard, and we will confirm compliance in writing within 48 hours.
"We installed 120 units of the 4" SS316 inline foot valve at our chemical blending facility. After 14 months, not a single failure. The Viton seals hold up against aggressive solvents. Thriveon has earned our trust."
"The customization process was incredibly smooth. We needed 3" BSP threads with a 1/16" screen. Thriveon delivered samples in 11 days – perfect fit. Now we order 500 units quarterly."
"Comparing quotes globally, Thriveon was not the cheapest but offered the best total value – quality, delivery, and warranty. Their epoxy coating is superior; we saw zero rust after 8 months in a humid offshore environment."
"I've been using Thriveon foot valves for three irrigation seasons. Prime holds perfectly even when the pump sits idle for weeks. The guys in the field love how easy they are to clean."
"We switched to Thriveon after quality issues with a Chinese supplier. Their QC is rigorous – every valve is pressure-tested before shipment. Incoming reject rate dropped to 0.2%. Highly recommend."
