An exciting valve that will revolutionize the industry. 

* Proportional control.                        * Small size and very lightweight.

* Surprisingly low cost.                      * Comes with standalone electronics.

Flexinol® actuator wire is used to proportionally control the airflow. This is a unique addition to a standard Schraeder valve core or stem like those found in automobile tires. Generally, these stems are "on" or "off" depending on whether the internal stem cap is "open" or "closed". The Electrostem™ Valve with Flexinol® actuator wires can very gradually open or close these caps to produce proportionally controlled airflow.
