Netherlocks FAITH partial stroke test device

The Netherlocks FAITH partial stroke test device is perfectly suited for maintenance purposes, saving valuable time

The ideal maintenance tool

FAITH is perfectly suited for maintenance purposes. When the actuator is in its blocked position, critical  components can be replaced at any time without  interrupting the process. Without the Netherlocks partial stroke testing system, control system components could only be replaced during a plant stop, when the actuator is in its fail position.
