Every time a centrifugal pump loses its prime, you're not just losing water — you're losing production time, maintenance budget, and operational reliability. Here are the real costs our clients faced before installing the right foot valve:
The function of a foot valve in a pump is deceptively simple: it sits at the bottom of the suction line and acts as a one-way gate. When the pump stops, the foot valve closes immediately, trapping water in the suction pipe so the pump never loses its prime. But not all foot valves are built equal. Here's what makes a Thriveon foot valve perform where others fail:
Precision-machined brass or stainless steel disc and seat ensure a bubble-tight seal at pressures up to 16 bar. Your pump stays primed even after days of inactivity — no manual re-priming needed.
Available in 316 stainless steel, ductile iron, and bronze to handle potable water, seawater, wastewater, and mild chemicals. Suitable for pH 4–10 and temperatures up to 120°C.
Built-in 304 stainless steel strainer (mesh size 20–60) catches debris before it enters the valve, protecting the sealing surface. Tool-free cleaning access — 60-second maintenance.
Streamlined full-bore design delivers CV values 20% higher than industry standard, reducing pressure drop and saving energy. Handles flow rates from 5 GPM to 2,500 GPM.
Spring-assisted closing mechanism ensures zero leakage even under low-pressure gravity conditions. Meets AWWA C508 and ISO 5208 Rate A standards.
From our factory in Northern China to US ports in 25–35 days. OEM/ODM orders ship in 15–20 days. We keep 5,000+ units in stock for immediate dispatch.

Get clear, practical answers to the most common questions from procurement and engineering teams.
The primary function of a foot valve in a pump is to maintain pump prime. It is installed at the bottom of the suction line and acts as a one-way check valve. When the pump stops, the foot valve closes automatically — trapping water inside the suction pipe. This prevents the pump from losing its prime, so it can start instantly without manual re-priming. It also prevents backflow and keeps debris from entering the pump.
While both prevent backflow, a foot valve is specifically designed for vertical installation at the end of a suction pipe and includes an integrated strainer (filter) to protect the pump from debris. Foot valves are engineered to create a bubble-tight seal at low pressure, which is critical for prime retention. Standard check valves may not seal reliably under low-pressure gravity conditions and typically do not include a strainer.
The best material depends on your fluid and operating environment:
Contact our engineers for a material recommendation based on your specific fluid chemistry and temperature.
As a general rule, the foot valve should be one size larger than the pump suction port to minimize pressure loss. For example, if your pump has a 2" suction, use a 2½" or 3" foot valve. We offer sizes from ½" to 12". Check our technical specs table above, or send us your pump details for a precise recommendation.

These are not scripted testimonials — they are genuine responses from our customers across the globe. We believe in transparency and letting our product speak for itself.
"We've been using Thriveon's 4" SS316 foot valves across 12 pump stations for the past 14 months. The function of foot valve in pump prime retention has been flawless. We previously used a well-known European brand but switched due to long lead times. Thriveon's quality is equal, if not better, and their delivery is consistently on time. Highly recommended for any serious pump application."
"I manage procurement for a large agricultural irrigation company. We need foot valves that can handle dirty water, high flow, and constant cycling. Thriveon's ductile iron foot valves with EPDM seats have been a game-changer. They last twice as long as the previous brand we used, and the price is significantly lower. The engineering team also helped us customize the strainer mesh size for our sandy water conditions."
"In desalination, reliability is everything. We trialed Thriveon's bronze foot valves on one of our RO feed pumps. After 6 months of continuous operation, we saw zero degradation in sealing performance. The valve held prime even during a 3-day plant shutdown. We're now rolling them out across all 8 of our production lines. The free sample program made the decision easy — no risk, all reward."
"We needed foot valves for a corrosive sodium hydroxide transfer system. Thriveon's engineering team recommended SS316 with PTFE seals. The valves arrived with full material certifications and performed exactly as specified. We've reduced our valve replacement frequency from every 4 months to over 12 months. The only minor issue was a slight delay in customs documentation, but the sales team resolved it within 24 hours."
"We've partnered with Thriveon for over 3 years as an OEM supplier of foot valves for our pump packages. Their consistent quality, ISO 9001 compliance, and ability to meet our custom branding requirements make them a reliable partner. We've received zero field failures from our end customers. The function of foot valve in pump systems is critical, and Thriveon delivers every time."
