Foot Valve 150MM
Product Overview
Foot Valve 150mm is a bottom-mounted check valve designed to maintain pump priming by preventing reverse flow in suction pipelines. It is widely used in water intake and transfer systems.
Key Features
Integrated stainless steel strainer prevents large particles and debris from entering the pipeline and pump system.
EPDM-coated disc sealing structure improves sealing performance and reduces backflow risk during shutdown.
Ductile iron body construction provides high mechanical strength and long service life under working pressure conditions.
Stainless steel internal components improve corrosion resistance in water and sewage applications.
Low opening resistance design helps reduce suction loss and improve pump operating efficiency.
Flanged connection configuration supports compatibility with multiple international piping standards.
