Proportional Electromagnetic Valves are designed to respond to variable power inputs to regulate the flow of liquids and gases proportionately. Valves are normally closed for added safety.

Pulse width modulated Driver Modules regulate the power supplied to Proportionating Electromagnetic Valves based on a reference signal. Set-point signals, 0-5 Vdc or 4-20 mA, input are employed to control the output pulse width modulated voltage at a fixed frequency (≈30KHz) and amplitude.

Stepping Motor Valve Stepping Motor Valve

Stepping Motor Valves (SMV) are designed for high flow regulation of liquids or gases. This line of electronic two-way metering valves has high precision linear stepping motors that drive the valve spindle.

Unlike solenoid operated valves, these Stepping Motor Valves stay cool during operation so there are no control operating problems due to coils heating up. In addition, these valves have extremely fine resolution with standard 0.0005"/step (optional 0.000125"/step available), as well as very low differential pressures and high operating pressures.
