Foot Valves for Motor-Driven Metering Pumps
Foot valves are non-return valves. They prevent the suction line from running dry and protect it from solid particles. They also function as a priming aid.

Overview
Prime and protect against contamination
Foot valves are fitted at the end of the suction line to prevent contamination and backflow.
During installation, ensure that there is a sufficient gap between the foot valve and the pump foot and between the foot valve and the lowest suction water level.
Union nuts and inserts/hose nozzles are included in the scope of supply with DN 10 and DN 15 foot valve sizes.
Important: Foot valves are not absolutely leak-tight shut-off devices!
Your benefits
- Protects the suction line from running dry (e.g. when changing tanks).
- to protect the metering pump from coarse particles of solids.
- Priming aid
