PSV proportional solenoid valve
PSV propotional electromagnetic valve for flow regulation of gases or liquids
PSV Proportionating Electromagnetic Valves are designed to respond to variable power inputs to regulate the flow of liquids and gases proportionately. For added safety PSV valves are normally closed (NC) when deenergized.
Flow is controlled by increasing or decreasing the voltage applied to the coil. This causes a magnetic force which raises the core and allows gas to flow.
PSV valves, constructed of stainless steel are available in five different sizes covering flow ranges from 3.5 sL/min to 100 sL/min air and 125 mL/min to 2.85 L/min water.
