Foot Valves Made in Tianjin China
Foot valves with a bottom inlet and vertical discharge, designed for suction line applications where a self-priming pump must draw fluid from a sump or reservoir without air entry.
Foot Valves Available From Stock Drawings
Model codes as they appear on our production drawings. Sizes and pressure ratings for each code are confirmed on quotation.
Buyers This Category Suits
- Water utility operators managing pumping stations with variable sump levels
- Power plant engineers installing feedwater pumps in auxiliary systems
- Chemical and pharmaceutical plants needing corrosion-resistant inlet protection
- Marine engineers fitting bilge or ballast pumps with reliable self-sealing suction
- Industrial contractors specifying reliable foot valves for sewage and process water systems
What It Fixes on the Line
- Air leaks into the suction line when the pump is off, causing loss of prime and failed restarts
- Sump water levels fluctuate, requiring a valve that stays open during flow but closes automatically when flow stops
- Unprotected suction inlets allow debris and sediment to enter the pump, leading to wear and blockage
- Existing foot valves lack corrosion resistance in aggressive water or chemical environments
- Valves with poor sealing fail to hold prime during extended pump downtime

Foot Valves FAQ
What is the function of a foot valve?
A foot valve is installed at the bottom of a suction line to allow fluid to enter while preventing backflow when the pump is off. This maintains prime and prevents air from entering the system.
Can the foot valve be used in high-pressure systems?
Yes. The foot valve series is rated from 0.05 to 4.0 MPa. The exact pressure rating for a specific model is confirmed on request.
What sizes are available?
The foot valve range covers nominal diameters from DN10 to DN2600. The exact size and pressure rating per model are confirmed on quotation.
What materials are used in the construction?
Materials are selected based on the application and medium. The valve body and disc are made from materials suitable for water, chemicals, and process fluids. Material details are confirmed on request.
Does the factory hold any certifications?
Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management certification. Test records for your order are issued on request.
Can the foot valve be supplied with a strainer?
Yes. Foot valves can be supplied with integrated strainers or as separate components. Configuration details are confirmed on request.
Is the valve suitable for marine or offshore use?
Yes. The foot valve is designed for use in shipping, marine, and offshore applications, including bilge and ballast systems, where reliable sealing and corrosion resistance are required.
