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

The Dorot S100 PR Series Cast Iron Angle Valve with 3-Way Selector is a heavy-duty hydraulic control valve engineered to automatically maintain a constant downstream pressure regardless of upstream fluctuations. Designed for use in irrigation networks, filtration stations, pump systems, and municipal water delivery, this valve offers compact angle-body construction to simplify layouts, reduce pressure loss, and eliminate the need for additional elbow fittings.

This model includes a built-in 3-way selector, enabling quick switching between automatic, manual open, and manual close modes—ideal for field servicing, startup testing, or emergency operation when external controls are unavailable. The diaphragm-actuated design ensures smooth modulation, reliable pressure reduction, and long service life with minimal maintenance.

With full compatibility across Dorot’s pilot valve range and constructed from corrosion-resistant cast iron, the S100 PR Angle Valve is the smart choice for durable and accurate pressure control in demanding environments.
