How it works:
Externally controlled solenoid valves are controlled via an external pilot valve. This design enables use under extreme conditions such as high temperatures, high pressures or heavily contaminated and aggressive media, as the control medium is separated from the working medium.
When to vote:
Externally controlled valves are ideal for applications where demanding media or extreme conditions prevail. Typical areas of application are industrial processes in which aggressive or contaminated media must be safely regulated.
Disadvantages:
More complex installation: Using an external pilot valve requires more complex installation.
Dependence on the control medium: The function of the valve depends on the availability and cleanliness of the control medium.
Typical applications:
Industrial plants: Control of aggressive media in the chemical industry or in high-temperature applications.
Process industry: Control of contaminated media or high pressures in industrial processes.
Power plants: control of steam and other high-temperature media.
"Made for extreme conditions – remotely controlled solenoid valves master even the toughest operating environments."
Maintenance and installation:
Higher maintenance effort: Both the pilot valve and the external controls require regular maintenance.
Installation: Careful installation required to ensure the reliability of the control medium.
Summary:
Externally operated solenoid valves provide reliable control for demanding applications under extreme conditions. They are the right choice for industrial processes where high temperatures, pressures or aggressive media must be handled.
