Dorot S75 B Series Reinforced Nylon Basic Hydraulic Valves with 3-Way Selector

The Dorot S75 B Series with 3-Way Selector is a versatile, durable hydraulic control valve designed for high-efficiency irrigation systems in open fields, orchards, and vineyards. Built from reinforced nylon and fitted with corrosion-resistant internal components, this valve combines rugged construction with precision hydraulic performance for long-term, trouble-free operation in demanding agricultural environments.

At its core, the S75 B Series features Dorot’s signature asymmetrical diaphragm, enabling smooth, surge-free operation, minimal head loss, and exceptional flow regulation—even at near-zero flow conditions. The inclusion of a 3-way selector provides flexible actuation, supporting hydraulic, electric, or combined control configurations. This makes the valve highly adaptable to a wide range of irrigation control systems and automation setups.

Designed for easy inline maintenance, the valve includes a removable flow control stem handle, an integral stainless steel filter, and bonnet-mounted control components for quick access. The hydrodynamic design ensures a wide water passage, achieving high flow capacity while maintaining low pressure drops.
