 IBAU TWO WAY VALVE
Pneumatic conveying systems for pulverulent bulk goods like cement, rawmeal, lime, flyash etc. often have to charge several silos one after the other. For many years and worldwide IBAU Two Way Valves have been used for changing the direction of flow in pneumatic conveying lines. The principle of these valves is simple and well known. A cast iron housing has one entrance socket and two discharge spouts. One of the discharge spouts is always closed by a disc while the other one is opened for the selected way. The valve disc is spring loaded and can be switched either manually or by a pneumatic piston actuator or by an el. motoric actuator. A torque motor with gear and brake forms the el. mot. actuator. This is to make sure thatthe final position is correct. Of course all remotely controlled valves are equipped with limit switches. Two way valves without actuator can have limit switches as an option. Limit switches can be of the conventional type as well as of the proximity switch type. |
