FAITH partial stroke test device allows live testing of critical valves

Testing without risk of overshoot

In close cooperation with one of their clients, Netherlocks recently produced a movie in which a live testing procedure of critcal valves is shown on location. It reveals how mechanical partial stroke testing allows live testing without interrupting process flow, while eliminating the risk of valve overshoot at the same time.

FAITH is a customized mounting set, installed between the valve and the actuator. It replaces the original bracket and drive bush. Inside the bracket, blocking pins can be positioned by pulling the test handle. These pins prohibit the drive bush from turning further than the preset test angle. The Netherlocks FAITH facilitates the partial stroke testing of valves without any risk of overshooting the test angle.

An experienced end user explains: “Before using FAITH, tests were difficult to plan and carry out as process flow could under no circumstances be interrupted. Now, valve tests can be carried out any time, while we can guarantee process flow to our clients at all times.”
