Dorot S100 PR/AQ Series Cast Iron Hydraulic Pressure Reducing/Electric Solenoid Valves with Aquative AC

The Dorot S100 PR/AQ Series is a dual-function hydraulic control valve that combines automatic pressure reducing functionality with 24V AC electric solenoid actuation, using the intelligent Aquative AC module. Built on Dorot’s reliable S100 diaphragm-actuated cast iron valve body, this model provides both precise downstream pressure regulation and remote On/Off capability, making it ideal for automated irrigation, filtration, and water distribution systems.

In standard operation, the pressure reducing pilot maintains a preset downstream pressure, protecting system components from pressure spikes or fluctuations. The Aquative AC solenoid enables integration with common irrigation controllers, allowing remote activation or shutdown of flow zones based on timer or sensor inputs. The result is a fully hydraulic valve that supports automated, energy-efficient water management.

This model is perfect for installations that demand both pressure stability and electrical automation, without sacrificing durability or manual control flexibility.
