Low Pressure Irrigation System
Irrigation from tanks, reservoirs, and pools with zero pressure. Automatic, programmable irrigation with motorized ball valve and Smart-Garden control unit.
Automate the entire irrigation process
The most effective solution for small tanks and low-pressure areas
Pressure Problem and Solution
Problem: Solenoid Valves
Why don't traditional solenoid valves work at low pressure?
- Requires a minimum pressure differential of 0.3-0.5 bar
- Insufficient pressure in gravity-fed systems
- No pressure builds up in small tanks
- The valve does not open or close completely
- Risk of water leakage and system failure
Solution: Motorized Ball Valve
Motorized valves operate even at zero pressure difference!
- Works at zero pressure differential
- Mechanical opening/closing with an electric motor
- Guaranteed fully open or fully closed
- No risk of leakage
- Silent and reliable operation
