Pressure control
SENTRONIC
The SENTRONIC valve with its internal control loop combines innovative pneumatic technology with the integrated analog electronics. This valve series allows for accurate adjustment of pressure, flow, force, speed, and linear or angular positions. All orifices have the same diameter for short response times when applying or exhausting pressure. The combined effect of all components assures a control behaviour at an extremely low hysteresis..
All SENTRONIC valves undergo automatic testing before leaving our manufacturing facilities. Each valve is provided with a test certificate showing all the test results.
OPERATING PRINCIPLE
Applying pressure

The pressurisation piston is operated and the flow from port 1 to port 2 is released.

 Maintaining pressure

The exhaust piston is in its central position: the flow between port 2 and port 1 or port 3 is blocked.

 Exhausting pressure

The exhaust piston is lifted and the flow from port 3 to port 2 is released.
