We see from your search that you're looking for information on the term "Proportional Valves",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Catalogue covers fluid control needs from
Burkert Fluid Control Systems, which we summarised at the time by saying "The catalogue includes Burkert's eControl 8611, the first modular control system designed for seamless integration into multiple closed-loop cooling systems".
The day before,
we featured the news release Small pressure regulator handles high flow rates from
Bosch Rexroth - Pneumatics: "Four ED02 series pressure regulators from Rexroth can be linked to each other without a base plate".
In December 2007, we covered the news from Burkert Fluid Control Systems
concerning its EControl 8611
- take a look at Controller handles flow, pressure and temperature
which says: "The multifunction eControl 8611 offers the most cost effective method to decentralise control in closed cooling loops".
Take a look also at the news release from Moog Controls, Valve handles demanding jobs,
as well as Valve line provides a range of options from Enfield Technologies,
and Teamwork is efficient solution for tyre presses from Parker Hannifin.
