Spider μProp® - Micro-proportional valves
Low-wear, infinitely adjustable & fast as lightning!

Infinite control

In combination with a flow or pressure sensor and a PID control loop, the Spider μProp can be used to continuously control gases or liquids.

Accuracy & repeatability

Our patented design enables smooth operation and movement of the armature. As a result, our Spider μProp can continuously regulate the flow with very high repetition accuracy over their entire service life.

Safety

Each valve is automatically set, calibrated and checked during the production process. This security ensures that our customers trust these valves and that they can also be used in extremely critical applications such as incubators for infants.

System integration

The low energy consumption and the compact design represent a real competitive advantage for portable devices and applications.

Spider μProp® - Micro Proportional Valves

 


We have brought all our competencies to embed all the key features of our Spider technology in a new proportional valves series: the Spider μProp. Already successful used in Respiratory, Fuel cell systems or in electronic Flow Regulators, the Spider μProp may be controlled using DC current or PWM in open or closed loop control.

Small, accurate, with a very long life time and easy to embed due to its cartridge design, the Spider μProp is used for precision dosing of the flow or pressure of gas and liquids in all kind of critical applications.The Spider μProp provides a fine, smooth and accurate regulation during the whole lifetime of your product!

These valves have a flat armature that moves between the seat and the solenoid. The flat armature is assembled together with a flat spring which presses the integrated sealing element against the valve seat in the de-energized position. Flat armature valves distinguish themselves by frictionless movement and very high life cycles. The Spider μProp are real proportional valves in which the armature stroke and thus the flow rate can be varied by the applied coil current.
