Dorot S80 B Series Reinforced Nylon Basic Hydraulic Angle Valves

The Dorot S80 B Series is a rugged and dependable hydraulic angle valve engineered for use in agricultural irrigation systems, filtration units, greenhouses, and open-field networks. Designed for optimal flow and easy installation, this valve delivers fast-acting hydraulic performance and minimal head loss in a compact, corrosion-resistant body.

Manufactured from high-grade reinforced nylon, the S80 B valve combines strength, UV stability, and chemical resistance for long-term use in harsh field conditions. The valve’s asymmetrical diaphragm and rigid plug mechanism ensure rapid opening and tight sealing—providing precise, stable operation across a wide range of pressures and flows.

Its angle-pattern body eliminates the need for elbow joints, reducing installation space and system pressure loss. The S80 B is available in sizes from DN40 to DN100 and can be configured with various end connections and control accessories for tailored system integration.
