Definition - What does Solenoid valve mean?
Commonly used to irrigate larger-scale crops, solenoid valves refer to the hydraulically-operated and electrically controlled valves that are found in most irrigation systems. These valves usually come with various types of electrical options, including 12Vdc and 12Vdc Latching and 24vAC, which is a prime choice for gardening. Solenoid valves can either be closed or open.
MaximumYield explains Solenoid valve
Unlike other irrigation valves, solenoid valves are electrically controlled to adjust the water flow. These valves are particularly advantageous to larger crops since they have a fairly robust construction and cab easily last for several years, as long as they are properly maintained. Most models are fitted with a manual flow latch, enabling gardeners to manually re-adjust the water flow according to the type of plants they are growing.
When using a solenoid valve, it is important to only opt for clean water. Dirty water can lead to leakages or clogging. In most cases, gardeners choose to install a filter on the valve’s supply latch. Electrical ball valves have been shown to be more resistant to dust and other pollutants.
