Automatic Irrigation Valves-Solenoid Valve
Automatic irrigation valves optimize irrigation processes and provide water at the desired times and in the desired amounts without the need for human intervention. These valves, which operate with electrical signals, control water flow quickly and reliably. The precise control provided by solenoid valves provides high precision by opening and closing water flow in milliseconds. It offers reliable performance with its robust and long-lasting structure. Solenoid valves, which can adapt to different pressure ranges, provide effective use of water resources while supporting optimal growth conditions for plants. When used together with automatic irrigation valves, it prevents water waste by optimizing irrigation processes and creates ideal conditions for plant development. These technologies are indispensable tools for those looking for sustainable and efficient irrigation solutions in agriculture and landscaping.
Where is Solenoid Valve Used?
Agricultural, Park, Garden, Landscape, Irrigation Systems: Solenoid valves are used to control the flow of water in drip irrigation systems, spray systems and similar irrigation systems, for irrigation automation and remote control.
- Fertilizer Injection: When fertilizer or chemical substances need to be injected into plants in agricultural applications, solenoid valves automatically perform this process.
- Greenhouse Control: Solenoid valves can be used to control temperature, humidity and other environmental factors in greenhouses. This ensures that plants have the best growth conditions.
- Water and Wastewater Processing: Controlling the flow of water is done with solenoid valves in irrigation systems and wastewater treatment plants.
Industrial pool filling: It fills the water level in pools to the desired level with sensor supports used. - Animal Watering: Solenoid valves can be used in animal watering systems. These systems automatically provide water to meet the water needs of animals.
- Feed Distribution: Solenoid valves can help distribute feeds in the right amounts and on time in feed distribution systems.
How Does a Solenoid Valve Work?
Solenoid valves are electromechanical devices that control the flow of fluids (liquid or gas) by converting electrical energy into mechanical energy. These valves start working when they receive an electrical signal. The electrical signal is transmitted to the solenoid coil, which acts as an electromagnet and creates a magnetic field. The resulting magnetic field moves the metal core (plunger) inside the valve. The movement of the core changes the position of the orifice (hole) inside the valve. When the core moves up, the orifice opens and allows fluid passage; when the core moves down, the orifice closes and prevents fluid passage.
In normally closed (NC) valves, the valve remains closed when electrical energy is cut off. When energy is applied, the magnetic force pulls the core up and the orifice opens and allows fluid passage. In normally open (NO) valves, the valve remains open when electrical energy is cut off. When energy is applied, the magnetic force pushes the core down and the orifice closes, preventing fluid passage. In pilot-controlled solenoid valves, the solenoid coil directly controls the pilot valve, not the main valve mechanism. The pilot valve changes the pressure on the main valve, allowing the main valve to open and close. When the power is cut off, the coil loses energy and the magnetic field disappears. When there is no magnetic field, the spring inside the valve pushes the core back to the original position of the orifice. In this way, normally closed valves close and normally open valves open.
Solenoid valves regulate the flow of fluids by working with electrical signals. The electric current applied to the coil creates a magnetic force, and this force moves the core inside the valve. This movement allows the valve to open or close, thus controlling the flow of fluid. When the power is cut off, the valve returns to its original position, thus providing reliable and automatic control.
