Digital Control Valve

A digital valve is a hydraulic control valve which is intended to achieve control with a high level of repeatability with an open-loop format. A stepping motor is incorporated inside as the electromagnetic actuator which drives the valve body in order to achieve this high repeatability. A stepping motor is a motor used for positioning control, and it has the high level of repeatability in the stop position. Another feature of this motor is the high level of repeatability which is achieved even with such a transient henomenon as that when the motor is activated. These features are utilized to ensure the high-cycle shock-less operation of hydraulic systems (mother systems). They also come into their own when controlling such time-based changes as in the force (thrust force) of the actuator (to increase or reduce the pressure).

Multi Stage Set-Stop Valve, F-2113-40R (Y-Pattern), F-113-40R (Globe) Size : 25 NB 400 NB This is an electrically actuated, hydraulically operated multifunction control valve. Used extensively in loading terminal automation systems in refineries and storage tanks of petroleum products for effective and accurate filling of tankers and railway wagons. It has two solenoid valves, receiving signal from batch controllers to position the valve for low flow / medium flow / high flow conditions as programmed.

Piston Digital Control Valve is an electrically actuated, hydraulically operated multi-function control valve. It can be used for local as well as remote controlled batching operations with electronic batch controller. The valve also offers an in-built flow governing function. Design Features: Fail-safe design : the valve is held closed upon loss of electric supply and/or line pressurePositive shut-off : meets ANSI Class VI for bubble- tight closureMulti-stage opening and closing : avoids static charge generation due to splashing of product in the beginning and foaming / overflow at the end, resulting in accurate deliveryLow pressure dropRectangular ports : for uniform valve response and linear controlBuilt-in flow rate control : no need of external pilots for flow rate control, when used with electronic batch controllerNo diaphragm Construction: The Alma Piston Digital Control Valve basically consists of a spring loaded piston, sliding in the guide liner, and two solenoid valves. Piston chamber formed between the liner and the piston top, is connected to the upstream and downstream pressures by normally open (NO) and normally closed (NC) solenoid valves respectively. Principle Of Operation: The Alma Piston Digital Control Valve works on the principle of "balanced piston". Piston is always exposed to high upstream pressure from its bottom side, whereas pressure in the piston chamber can be varied with the help of solenoid valves. When pressure in the piston chamber is equal to the high upstream pressure, the top spring acts as a differential force, pushing the piston down on the valve seat and the valve is held tightly-closed. When pressure in the piston chamber is relieved with the help of solenoid valves, a differential pressure is created across the piston. The high upstream pressure below the piston overcomes the top pressure plus the spring force and pushes the piston up, resulting in valve opening and the flow starts.

Fail-safe design Low pressure drop Bubble-tight seat design Flow rate control PRINCIPLE OF OPERATION The Digital Control Valve basically consists of a diaphragm operated main valve and two solenoid valves. Normally open (NO) solenoid connects the valve cover chamber to the upstream pressure, whereas normally closed (NC) solenoid connects the valve cover chamber to the downstream pressure. When the Digital Control Valve is used with an electronic batch controller, it can be digitally controlled by operating the solenoid valves through any of these three stages : when NO and NC solenoids are energised, the valve opens gradually. when NC solenoid is de-energised (keeping NO solenoid energised), the valve locks at its current position. when NO and NC solenoids are de-energised, the valve closes gradually.
