GSV is a lightweight resin solenoid valve for automatic watering of greenbelts, protected horticulture, parks and urban greenery. It is a pilot operated diaphragm type and can also be used with diluted agricultural chemicals and liquid fertilizers. Continuously energized and latch pulse signal types are available, with Rc1 equivalent (25A) and Rc2 equivalent (50A) ports.
