Engineered for water, wastewater, and industrial applications – our ductile iron foot valve prevents backflow, maintains prime, and reduces downtime. Trusted by US pump distributors and plant managers since 2008.
❌ Frequent Clogging & Backflow
Standard cast iron foot valves often get stuck due to debris, causing pump losing prime. Reports show up to 30% increase in maintenance calls.
❌ Corrosion & Short Lifespan
Many cheap valves use inferior materials that rust quickly in water/wastewater, requiring replacement every 12-18 months.
❌ High Shipping & Import Delays
Overseas suppliers often miss deadlines or add hidden freight costs. Typical lead times stretch to 60+ days, disrupting project schedules.
❌ Lack of Technical Support
Many manufacturers offer no engineering backup. When specs are wrong, you’re left with non-returnable stock.
Our foot valves are crafted from high-grade ductile iron (GGG40/50) with stainless steel spring and PCV disc, offering exceptional strength and durability. Designed for flanged connections – ideal for water pumps, irrigation, and fire protection systems.
Ductile iron body (ASTM A536) with fusion-bonded epoxy coating – resists corrosion, abrasion, and chemicals. Tested for 10,000+ cycles.
CNC-machined seat and Buna-N disc ensure bubble-tight shut-off. Low cracking pressure (0.5 psi) prevents pump dry run.
Flange drilling per ANSI B16.1 class 125/150. Available in sizes 2” to 12”. Fully interchangeable with major brands.
We stock popular sizes for quick shipment (15-20 days FOB Tianjin). Custom painting, logo, and packaging available.

A ductile iron foot valve is installed at the bottom of a pump suction line to keep the pump primed and prevent backflow. It uses a spring-loaded disc that opens under pump suction and closes when flow stops. Ductile iron provides higher strength and shock resistance compared to gray iron, making it ideal for pressure applications.
We stock sizes 2” (DN50) to 12” (DN300) in ANSI B16.1 class 125/150 flanges. Custom drilling for DIN, JIS, and other standards is available for OEM orders. Contact us for non-standard dimensions.
Yes. We offer full OEM/ODM services: custom painting (any RAL color), laser engraving, private label packaging, and special thread or gasket options. MOQ for OEM is typically 50 pcs per size. Request a custom quote.
Typical lead time is 15-25 days for stock items (FOB Tianjin). For bulk orders, 30-35 days. We work with major freight forwarders (MSC, Maersk) to secure competitive rates.
