Plastic Valves Series Dorot Series Series plastic valves are designed to control irrigation systems for crop fields, vineyards and orchards. This series boasts exceptional hydraulic characteristics enabling high flow rates, while operating at low head loss. A wide range of control functions allow designing and operating optimal irrigation networks. Features: Simple structure Superb hydraulic performance - unmatched high flow capacity Durable, corrosion free materials Unique clog-free labyrinth inlet in the electric -way valves Optional check feature Operates at a wide range of flow rates, from near zero to maximal flow Electric -way or hydraulic / electric -way actuation Optional flow control throttle handle Simple & Easy maintenance Suitable for Low pressure systems Edition 09/0

Plastic Valves Series Operating principle: Way Control Closed mode Open mode Modulating mode When inlet pressure is applied to the control chamber the valve closes drip-tight. When the operating pressure is relieved from the control chamber, the line pressure at the valve inlet opens the valve. The position of the diaphragm is dictated by the volume of water in the control chamber, which is regulated by the pilot valve in order to maintain a preset pressure value. Way Electric-Control Closed mode Open mode A solenoid operator plugs the control chamber s outlet. A permanent connection from the upstream through a labyrinth restriction ensures line pressure into the chamber closing the valve. Energizing the solenoid operator opens a drain to the downstream, allowing the valve to open. Edition 09/0
