Dorot S100 M Series Cast Iron Basic Electric 24AC Electric Solenoid Valves Manual On/Off

The Dorot S100 M Series is a cast iron diaphragm-actuated valve equipped with a 24V AC electric solenoid and integrated manual On/Off override, offering simple and reliable flow control for irrigation networks, filtration systems, and water distribution lines.

Controlled remotely via a 24V AC signal, the solenoid pilot allows the main valve to open or close in response to system demands—ideal for integration into automated irrigation controllers and PLC-based systems. For added convenience and reliability, the manual override function allows local valve operation in the event of power failure, testing, or commissioning, without the need to disconnect wiring or remove components.

Engineered with Dorot’s proven direct-sealing diaphragm design, the S100 M Series provides tight shut-off, low head loss, and trouble-free operation even under dirty water or fluctuating pressure conditions.
