ADI High Performance Plastic Hydraulic Control Valves

The ADI Series is a line of plastic hydraulic/electric control valves for residential, commercial, and agricultural irrigation systems. This diaphragm-actuated hydraulically operated plastic control valve combines simple and reliable construction with good hydraulic performance.
The ADI Series Valves are durable plastic valves. The valve body, cover, and seal disk assembly construction material uses Glass-Filled Nylon to meet rough service conditions obtaining high chemical and cavitation resistance.
The valve body design includes a full bore seat with an unobstructed flow path, free of any in-line ribs, supporting cages, or shafts.
Its seal disk assembly includes a flexible, carefully balanced, and peripherally supported diaphragm and a rugged guided plug with an elastomeric sealing surface

Main Features and Benefits

●Durable, industrial-grade valve design and construction with fiberglass-filled nylon to meet harsh service conditions
●Full-bore seat for ultra-high flow and minimal pressure loss
●Fewer parts, simple structure design, easy installation and maintenance
●Plug-in handle provides precise flow adjustment
●Accurate and stable pressure regulation, stable operation
●Low starting and driving pressure
●High-quality diaphragm, resistant to erosion and deformation

The valve is a hydraulically self-operated, diaphragm-actuated control valve, which uses the hydraulic force of the line pressure to reduce higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.

The pilot continuously senses the downstream valve pressure and controls the valve’s opening and closing rate accordingly, by increasing or decreasing the flow from the valve control chamber to downstream.
