Dorot S100 B Series Cast Iron Basic Hydraulic Angle Valves with 3-Way Selector

The Dorot S100 B Series Cast Iron Angle Valve with 3-Way Selector is a heavy-duty hydraulic valve designed for on/off or modulating flow control in agricultural irrigation systems, water distribution networks, and filtration stations. Its 90° angle-pattern body offers a compact footprint and eliminates the need for additional elbows—making it ideal for tight installations and minimizing pressure losses.

This model is equipped with a built-in 3-way manual selector, allowing operators to easily switch between automatic, manual open, and manual close modes. This feature enables quick manual operation in the field—ideal for commissioning, testing, or override during maintenance or power outages—without needing disassembly or external tools.

Manufactured from rugged cast iron and built around Dorot’s proven diaphragm-sealing technology, the valve ensures reliable, tight shut-off and long-term performance in challenging environments, including systems with sediment or aggressive water chemistry.
