Proportional valves

Proportional valves

ASCO is leader in the proportional valve industry, thanks to a complete line of products for every need. Thanks to the operation based on an electrical signal, these valves offer rapid response and constant and accurate control of the flow, as required by many industrial applications.

Among the features that ASCO proportional valves offer are: flow rates adjustable between 0% and 100% of the rating, possibility of flow adjustment from different electrical inputs (sensors, transmitters, PLC, etc.) through a control unit, plus they can be used with air, gas, vacuum, and for precise control of the flow of water.
