  • Easy-control
  • Full scale linearity flow rate control
Series PM provides series FC with the required power and control signal (step and direction). It controls the step of a bipolar stepper motor with an analogue signal (1-10 Vdc/4-20mA/RS485 Modbus).

Utilizing the industry’s most robust and powerful linear actuator, the high-flow stepper-controlled proportional valve outperforms the competition in performance and durability.
This valve is ideal in critical applications such as gas delivery, medical, analytical, and industrial automation requiring high resolution, high flow, and low hysteresis. In addition, the unique design allows for custom flow profiles when required.
