Designed to reduce water loss due to deep seepage in poly tubing irrigation systems.
This valve has the advantage of handling water flow of 6 to 7 liters per second, substantially reducing water loss due to seepage and maintaining balanced irrigation of 1000 to 1200 cubic meters of water per hectare.

The following is a comparison of different irrigation systems studied in sugar cane production in Valle del Cauca, Colombiar:
|
Irrigation Ditch |
Watering type |
Number of siphons |
Siphon type |
Flow rate (liters per second) |
Consumption (cubic meters of water per hectare) |
|---|---|---|---|---|---|
| Made by trencher | Continuous furrow | 1 | 3 inch PVC | 3.5 (using one siphon) | 1,800-2,000 |
| Made by trencher | Continuous furrow | 2 | 3 inch PVC | 7 (using two siphons) | 1,600 |
| Made by trencher | Alternating furrows | 2 | 3 inch PVC | 7 (using two siphons) | 1,200-1,300 |

Irrigation Ditch |
Watering type |
Valve Type |
Flow rate (liters per second) |
Consumption (cubic meters of water per hectare) |
|---|---|---|---|---|
| Unnecessary | Alternating furrows | 3.5 inch gate valve | 7 (using one gate valve) | 1,000 – 1,200 |
Water loss due to transport is reduced by using poly tubing, and deep leakage is decreased due to the increased flow rate that the 3.5-inch gate valve makes possible.
