Dorot S100 PR Cast Iron Basic Hydraulic Pressure Reducing Angle Valve with 3-Way Pressure Selector Valve

The Dorot S100 PR Series Angle Valve with 3-Way Pressure Selector Valve is a pilot-operated hydraulic control valve engineered to automatically maintain a constant downstream pressure, regardless of fluctuations in upstream supply. Featuring a 90° angle-pattern body, this valve eliminates the need for external elbow fittings—ideal for compact installations in irrigation networks, pump stations, filter banks, and municipal pressure zones.

Fitted with a 3-way pressure selector valve, the S100 PR Angle model allows seamless switching between automatic pressure control, manual open, and manual closed positions—enabling fast field override and servicing without tools or disassembly.

Constructed from corrosion-resistant cast iron and incorporating Dorot’s trusted diaphragm-actuated design, this valve ensures tight shut-off, smooth modulation, and minimal pressure loss, even under challenging water conditions.
