The Damcos KF/KFR is a linear single-acting spring-closing Actuator that is equipped with a unique emergency system. The Damcos KF and KFR are operated by hydraulic pressure. The output spindle is lifted, which opens the valve, and the spring package is compressed.
When released, the spindle closes on the valve with end closing thrust (spring) of 1500 – 16500 Nm. When the hydraulic pressure is not available in an emergency, a built-in manual hand pump can be used to operate the Actuator.
