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

FAQ

Solenoid valves require a minimum pressure differential to operate (usually 0.3-0.5 bar). Motorized ball valves, on the other hand, open and close mechanically with an electric motor, allowing them to operate reliably even at zero pressure differential.
Valve selection is based on your flow rate needs. 1/2 inch valves are recommended for small drip irrigation systems, 3/4 inch for medium-scale garden and greenhouse systems, and 1 inch for high-flow large systems.
Yes, Smart-Garden control units operate with an internal 5000mAh rechargeable battery. Additionally, a solar panel charging option is available with an optional 1-5W panel. Battery life can last for months depending on usage conditions.
Yes, it can work integrated with soil moisture sensors, rain sensors, and temperature sensors. It can make automatic irrigation decisions based on sensor data; for example, if the soil is moist, irrigation can be skipped.
Installation is quite simple. Connect the motorized valve to the reservoir/tank outlet (threaded connection), connect the cables from the control unit to the valve, download the mobile app, and follow the setup wizard. We also offer professional installation support if needed.
