RO Solenoid Valve are electrically actuated devices that are used within the flow lines of the reverse osmosis water purification systems to control the flow rate. These components are installed with a conductive coil that when energized or de-energized open or closes the flow lines respectively. There are many different types of such flow control units availed with a voltage rating of between 12 to 24 volts. Top-grade hard plastic is used for the fabrication of these units that make them capable to withstand high temperature and pressure that ultimately leads to longer service life and low maintenance.
