Brass Foot Valve – 1 in (Model TFV100NL)

The TFV100NL 1‑Inch Brass Foot Valve is a heavy‑duty check valve designed to maintain pump prime and prevent reverse flow in water suction lines. Installed at the end of an intake or suction pipe, this foot valve allows water to flow toward the pump while automatically closing when the pump shuts off, keeping the line full and ready for the next operating cycle.

Constructed from solid brass, the TFV100NL offers excellent corrosion resistance, durability, and long‑term reliability in demanding water system environments. It is an essential component for shallow well systems, jet pumps, and water transfer applications where consistent performance and pump protection are critical.

Product Description

The TFV100NL Brass Foot Valve is engineered to ensure reliable pump operation by preventing loss of prime and unwanted backflow. When the pump is running, the valve opens to allow water to flow upward through the suction line. When the pump shuts off, the internal mechanism closes automatically, holding water in the line and preventing air from entering the system.

Its solid brass construction resists rust, corrosion, and mineral buildup, making it well suited for continuous exposure to water and submerged environments. By maintaining prime, the foot valve reduces pump wear, improves startup efficiency, and helps extend overall system life.

This valve is commonly used in residential, agricultural, and light commercial water systems where dependable suction‑side performance is required.
