Foot Valves

Foot valves are used in liquid pipeline systems where reverse flow needs to be prevented, especially in water, agricultural, potable water, sewage and pump station applications.

This category includes Foot Valve Ball Type PN10-16-25 and Foot Valve Spring Type PN10-16-25. Both products are listed for applications with non-corrosive liquids and a maximum temperature of 80°C.

Available Foot Valve Products

Foot Valve Ball Type PN10-16-25

Foot Valve Ball Type PN10-16-25 is used in industrial, agricultural and water line systems, potable water systems and pump stations.

The catalog describes this model as a full bore valve with easy installation and maintenance, low pressure drop and self-cleaning property due to the continuous movement of the ball.

Foot Valve Spring Type PN10-16-25

Foot Valve Spring Type PN10-16-25 is used in industrial, agricultural, potable water, sewage systems and non-corrosive liquid applications.

This model is used to prevent backflow of liquid and hammer effect, especially in pump stations. The catalog mentions that it can be installed in different positions, vertically or horizontally.

Applications

• Industrial systems
• Agricultural systems
• Water line systems
• Potable water systems
• Sewage systems
• Pump stations
• Non-corrosive liquid service up to 80°C

Main Features

Foot valves in this category are used where reverse-flow prevention is required in liquid lines.

The Ball Type model is described with full bore design, low pressure drop and self-cleaning behavior due to the continuous movement of the ball.

The Spring Type model is described with a spring-type blocking mechanism and is used to prevent backflow and hammer effect.
