Digital Control Valves
The Digital Control Valve consists of a valve tubed with two solenoid valves. The solenoids are configured in normally open & normally closed position. These solenoids are connected to electronic batch controller. The batch controller provides signal to carry out two functions. Multistage opening & closing function to get smooth flow control, and precise batch quantities during loading operation of loading racks, Bulk Plants or processing installations.
The Digital Control Valve are hydraulic, diaphragm actuated control valves. The “Y” type globe body is a hydro dynamically balanced design for high flow rates, minimum head loss and maximum cavitation resistance. The valve body includes a full bore removable seat provided with a bottom guide rib for maximum assurance of complete valve shutoff. The entire actuator assembly may be removed as a unit using only simple common hand tools. The diaphragm actuator and trim provide smooth, accurate and controlled operation assuring bubble tight shut offs.
