German manufacturer KTC Systemtechnik produces hydraulic and electro-hydraulic actuators for more than 10 years. They are specialized in compact electro-hydraulic fail-safe actuators up to 10.000Nm. With the new development, a very simple configurable positioner electronic unit, KTC Systemtechnik standard fail-safe actuators are now able to take over modulating service for quarter-turn or linear operated valves. This might save an additional control valve in line.
