Top 3 Questions

In the case of stainless steel compensators, they are always designed on customer-specific process and media data. This requires medium, pressure, temperature, axial, lateral and angular movement.


As soon as the board for the positioning system is installed and connected correctly, the actuator is only approached via the control signal (depending on the setting 4-20mA, 0-20mA, 0-10V or 1-10V). A 90° swivel is still possible, but must be specified via the control signal, an automatic swivel is no longer possible.


The membrane-operated pressure reducing valve is frequently used in applications with low to normal back pressure. Due to the membrane, it also delivers more sensitive regulation.

The piston-operated pressure reducing valve is frequently used with high back pressures and aggressive media. It has an extremely robust design, giving it a high level of safety in case of pressure surges.
