Dorot S100 PR Series Cast Iron Basic Hydraulic High Pressure Reducing Valves with 8mm Nylon Tubing

The Dorot S100 PR Series High Pressure Reducing Valve is a pilot-operated diaphragm valve designed to automatically regulate downstream pressure in water supply, irrigation, and industrial fluid systems operating under elevated pressure conditions. This version is equipped with reinforced 8mm nylon control tubing, offering superior mechanical strength and resistance to UV, abrasion, and environmental wear—ideal for high-pressure or rugged field environments.

Built on Dorot’s proven cast iron S100 valve body, the valve uses a high-pressure-rated diaphragm and pressure-reducing pilot to maintain a preset outlet pressure, regardless of fluctuating upstream conditions. The durable 8mm nylon tubing ensures reliable pilot operation under higher pressures and longer distances, minimizing the risk of leaks or damage in exposed installations.

This configuration is best suited for filtration stations, booster pump discharge control, high-pressure irrigation mainlines, and pressure-sensitive infrastructure.
