Dorot S90 B Series UPVC Basic Hydraulic Valves

The Dorot S90 B Series is a cost-effective and corrosion-resistant basic hydraulic valve designed for efficient on/off control in agricultural irrigation systems. Ideal for open fields, greenhouses, and filtration networks, this valve is built from robust uPVC and reinforced polymers, making it a reliable choice for installations where aggressive water quality or chemical exposure may be present.

At the heart of the S90 B Series is a flexible, large-diameter diaphragm that provides responsive operation, excellent sealing, and smooth modulation across a wide flow range. The angle body design reduces friction loss and enables compact installation without the need for elbow fittings—resulting in lower pressure drop and improved hydraulic performance.

Simple to install and service in the field, the S90 B is available with threaded or solvent-welded end connections and is well-suited for both above-ground and underground setups.
