Uses :

Suction Line of Irrigation Pumps:

• Installed at the bottom of suction pipes in open wells, sumps, ponds, or tanks.
• Prevents water from draining out of the suction line when the pump is switched off.
• Keeps the line primed (filled with water), ensuring the pump starts easily next time.

Prevents Debris Entry:

• The foot valve has a filter screen or strainer that stops leaves, sand, and debris from entering the pump and damaging it.
• Crucial for systems using non-filtered or open water sources.

Ensures One-Way Flow (NRV Function):

• Ball-type mechanism allows water to flow upwards only and closes quickly if water tries to flow back down.
• Protects pump and system from back pressure or reverse water hammer.

Used in Drip, Sprinkler, and Lift Irrigation Systems:

• Supports consistent suction pressure in large drip or sprinkler irrigation setups.
• Especially useful in lift irrigation schemes where long suction lines are used.
