Ideal for controlling sensitive media containing solid particles

On account of their favorable flow characteristic LIAG® arc valves are particularly suited for proportioning viscous and pasty products. Depending on the product to be proportioned LIAG® arc valves can be delivered with various shutter qualities and linearization inserts. Control is performed via a standard 4-20mA (0-10V) electrical actuator. The control characteristic / rate of flow or the control range can be adapted to customers requirements.
