ASCO Proportional Valves control the flow of neutral fluids. By varying the input current you can precisely adjust the valve's flow rate. This eliminates the need for a variable flow system to contain multiple valves with different flow rates.

Proportional Valve Application examples include:

• Anesthesia Equipment
• Blood Pressure Monitoring (non-invasive)
• Endoscopy Equipment
• Gas Chromatography
• Respirators
• Ventilators
