DN25–DN200 PPR Foot Valves / Bottom Valves – Factory Direct from China

Our DN25 to DN200 PPR Foot Valves (also known as bottom valves) are high-performance plastic valves designed for installation at the submerged end of pump suction lines. These valves function as one-way check valves, preventing water hammer and backflow by allowing fluid to enter the pump system while stopping reverse flow when the pump stops.

Manufactured from high-quality polypropylene random copolymer (PPR) , these foot valves offer excellent corrosion resistance, lightweight construction, and easy installation across a broad range of industrial, agricultural, and municipal applications. As a leading manufacturer in China, we supply these valves globally with competitive pricing and reliable lead times.

Key Features & Benefits

PPR Material Construction: Provides excellent resistance to acids, alkalis, and corrosion, ensuring long service life in aggressive fluid environments

One-Way Flow Design: Floating ball or clack mechanism automatically opens under suction pressure and closes when the pump stops, preventing pipe emptying and pump priming loss

Non-Blocking Design: Multiple water inlet ports and reinforced ribs on the valve cover prevent clogging, reducing maintenance requirements

Lightweight & Easy Installation: PPR construction significantly reduces weight compared to metal alternatives, simplifying handling and installation

Broad Size Range: Available from DN25 to DN200, covering most standard pump suction applications

Compliant with Drinking Water Standards: Bacteriologically neutral and hygienic, suitable for potable water systems
