A horizontal foot valve is designed for installation in a horizontal suction line, with the strainer oriented horizontally. This allows easy cleaning and inspection without draining the entire pipe. A vertical foot valve hangs directly below the pump in a drop pipe. Horizontal valves are preferred where space allows because they reduce the risk of debris settling on the seat and are simpler to service.

Yes, our horizontal foot valve design works reliably with VFD-driven pumps. The poppet closes gently as flow decreases, preventing slam shut. We recommend the Viton® seat option if your water temperature exceeds 180°F or if the pump operates at low speeds (<30 Hz) for extended periods.

The standard mesh (20×20×0.9 mm) suits most clean water and HVAC applications. If your system has fine sand or silt, use 30 or 40 mesh. For raw water with larger debris, choose 10 mesh. Our engineers can recommend the optimum mesh based on your water quality analysis — just send us a sample report.

For standard 2"–12" cast iron horizontal foot valves, there is no MOQ — you can order a single unit for testing. For stainless steel (CF8M/CF3M) or sizes above 12", the MOQ is typically 10–20 units, but we can produce fewer with a small setup surcharge. We keep popular sizes (4", 6", 8") in stock for immediate shipment.

We ship via sea freight (FOB Tianjin or CIF to your nearest US port) or air freight (DDP available). For sea shipments, transit time is 25–35 days to Los Angeles, Seattle, or New York. We handle all export documentation (bill of lading, packing list, certificate of origin, and material test reports). Many US buyers use a customs broker for clearance — we provide all required paperwork.

Absolutely. We offer sample valves at cost + shipping. If you place a production order within 60 days, we deduct the sample cost from your invoice. Samples are built to the same standard as production units — no "sample-grade" shortcuts. Contact our team with your size and material requirements.

Standard terms: T/T (30% deposit, 70% balance before shipment). For established US customers with good credit history, we offer L/C at sight or net 30 upon approval (order value up to $25,000). We also accept credit cards (Visa/MC) for sample orders and small amounts.

We recommend checking with your local mechanical inspector or AHJ. For potable water systems, our NSF 61-certified option meets most US requirements. For fire protection systems, we offer UL/FM approved models. We provide a compliance checklist with every quotation — just tell us your application and state.
