Chengxin Valve's Cast Iron Threaded Foot Valve is engineered to deliver unmatched reliability for submersible pump systems. With its robust anti-clog design and 1-1/4 inch threaded connection, this valve ensures continuous fluid intake while preventing debris accumulation. Manufactured since 1993 in our ISO-certified facility, it offers a durable solution for challenging environments across agriculture, industrial water supply, and irrigation applications.
The valve's heavy-duty cast iron construction withstands corrosive elements and high-pressure operations, significantly extending equipment lifespan. Its specialized strainer design reduces maintenance frequency by 40% compared to conventional models, translating to lower operational costs. Ideal for deep well installations, this component acts as the first line of defense against pump damage caused by dry running or sediment ingress.
Core Technical Specifications:
| Parameter | Value |
| Operating Pressure | Up to 150 PSI |
| Temperature Range | -20°C to 120°C |
| Thread Standard | NPT (National Pipe Thread) |
| Strainer Surface Area | 30% larger than standard models |
Key Advantages for Industrial Users:
Corrosion Resistance: Epoxy-coated interior prevents rust formation in acidic or saline water conditions
360° Filtration: Perforated basket design captures particulates from all directions without flow reduction
Quick-Clean Mechanism: Removable strainer assembly enables maintenance without pipe disassembly
Leak-Proof Seal: Dual-rubber gasket system maintains vacuum integrity at depths exceeding 30 meters
Performance Comparison:
| Feature | Standard Foot Valve | Our Anti-Clog Model |
| Average Maintenance Interval | 3 months | 8-12 months |
| Flow Rate Retention | Declines 45% in 6 months | Maintains 90% after 1 year |
| Sediment Handling Capacity | Up to 1mm particles | Handles 3mm particles |
Installation Flexibility: The valve's threaded connection simplifies integration with existing submersible pump setups, requiring no specialized tools. Its compact profile allows deployment in narrow boreholes while the weighted base promotes stable vertical positioning. Compatible with PVC, steel, and composite suction pipes through standard adaptors.
Note: Custom screen mesh configurations (0.5mm to 5mm) are available for specific water quality conditions upon request. Consult our engineering team for high-silt applications.
Global Compliance: Manufactured under ISO9001 quality management and ISO14000 environmental standards, each valve undergoes three-stage pressure testing. Our OHSAS18001 certification ensures ethical production practices. The product meets AWWA C508 specifications for valve performance and material safety.
Why professionals choose Chengxin: With 30+ years of valve manufacturing expertise and direct export capabilities from major Chinese ports, we guarantee timely delivery to South America, Eastern Europe, Africa, and the Middle East. Our 101-200 employee facility maintains strict batch traceability – each valve carries a unique quality control ID.

Frequently Asked Questions
Q1: What distinguishes this foot valve from plastic alternatives?
Cast iron construction provides superior structural integrity in deep-well applications where high pressure and abrasive sediments degrade plastic components. Our valve withstands impact during installation and resists UV degradation.
Q2: How does the anti-clog feature function?
The conical strainer design creates turbulent flow that prevents particulate buildup. Larger surface area (vs standard models) reduces velocity at intake points, allowing debris to fall away instead of adhering to screens.
Q3: Is this compatible with 1-inch suction pipes?
While designed for 1-1/4 inch systems, reducer bushings for 1-inch connections are available. Specify required adaptors when ordering to ensure proper fitment.
Q4: What maintenance is required?
In typical operation, inspect every 6 months. The quick-release mechanism allows strainer cleaning without removing the valve body. Replacement kits for wear components (gaskets, strainers) are available.
Q5: Do you provide installation guidance?
Comprehensive installation manuals with torque specifications and alignment diagrams accompany each shipment. Video tutorials can be accessed via our product support portal.
Q6: What is the lead time for bulk orders?
Standard orders ship within 7 days. For quantities exceeding 500 units, production typically requires 15-20 days. Express shipping options available from Tianjin/Qingdao ports.
