solenoid-valvesSolenoid Valves

Solenoid valves are used mostly for clean media such as liquids or gases. For the solenoid valves we distinguish between:

  • Pilot Solenoid Valves are used for piloting pneumatic valve actuators. For this purpose media such as filtered, lubricated or oil-free compressed air and inert, gaseous fluids can be used.
  • Process Solenoid Valves are used directly in the process, e.g. as in dosing.

Process Automation

Measuring, control and regulation are the main components in process automation. For these applications, SED has electro-pneumatic positioners in the program.

These can be both centrally mounted on the process valve, or even mounted sideways for process valves with large stroke range, and also operated remotely if necessary.

Contact Us for further details.

Control and Monitoring

Based on many years of experience of SED in using and manufacturing of components for process valves, we offer a wide range of automation technology for linear actuators.

These range from the simple optical position indicator to our electrical position indicators, which can monitor up to 3-valve positions. In essence, these solutions are based on mechanical limit switches, proximity switches or potentiometers.

Our accessories can also be assembled with simple mounting options to other valve brands.
