Proportional Solenoid Valves

Product Introduction

Solenoid valve designed for applications that freely control the output flow rate. Flow rates from valve closed to valve fully open (0-100%) can be output proportional to the input current value unlike other electromagnetic valves.

Enables automation of flow rate adjustments.

It has been adopted in various fields such as for semiconductors, medical treatment, and general industrial equipment.


  1. High Precision

    High precision of the control current value enables highly accurate flow adjustment.

    In addition, since the drive unit including the valve body is designed horizontally with no sliding parts, there is little turbulence in the flow rate and it has a long life cycle.

  2. Manufactured in a Clean Room

    The gas contact parts are oil-free and are manufactured in a clean room, so they are hygienic valves with reduced contaminants.

  3. The piping connection method can be flexibly supported.

  4. Customization Available

    We will customize shape and specifications to your design.

Product Features

Outputs a flow rate proportional to the current

  • By increasing or decreasing the current value of the controller, the flow rate can be adjusted steplessly.
  • The Cv value is calculated at the standard flow rate, and the valve itself can output above the standard flow rate (maximum flow rate). 　 Therefore, there is no need to worry about a decrease in the output flow rate during continuous use.

High-precision, long-lasting lateral construction with no sliding of the drive unit

  • Since the drive unit containing the valve plug is supported vertically by plate springs ① and ②, there are no sliding parts. Therefore, there is no wobble or flow change during operation, and the valve has a long lifecycle since there is no deterioration caused by sliding.
  • The patented high pull force lateral construction ensures stable proportional characteristics, allowing a large flow rate to be controlled with a small solenoid.
  • The valve body is made of PTFE material for high corrosion resistance. In addition, the valve body does not stick to the valve seat, which occurs with rubber valve bodies, so the valve can be used stably.
