Proportional Solenoid Valves

Proportional solenoid valves provide variable flow control for a wide range of applications.

The Valves Control Flow based on Applied Voltage 

Solenoid Solutions' Wattmizer Proportional Valves are designed to regulate the flow of air and gas varying the output flow based on the applied current input to the valve. However, these valves do not operate as shut-off valves. The valves are 2 way, normally closed and are available with a 9 watt coil featuring a combination of 12 or 24 VDC voltages with 1/16" or 3/32" orifices. These valves provide an adjustable programmable controller, ideal for mixing gases. Every valve is fine tuned to each application, and they are 100% laboratory tested. These proportional valves are economically priced, and available in a wide range of materials, components and configurations.

Maximum Hysteresis*
 15%
* Hysteresis - If an alternating magnetic field is applied to the material, its magnetization will trace out a loop called a hysteresis loop. The lack of retraceability of the magnetization curve is the property called hysteresis and it is related to the existence of magnetic domains in the material.

Flow Diagrams

Review all the possible 2-Way, 3-Way, Normally Open and Normally Closed valve configurations.

CV Calculator

Based on the media passing through the valve, understand and calculate the Flow Coefficient or CV and the Differential Pressure (delta P) between the inlet and outlet of a valve.

Valve Considerations

Many applications have critical design factors to consider when developing a custom valve solution. Whether its limited space, a corrosive fluid, power constraints or high vibration, we help you design the right solution.
