An Antwerp based leading global synthetics company uses partial stroke testing to test the availability of some of their most critical ESD valves. Remarkably, they found that some valves that performed spotless in full stroke tests during stops, turned out to be stuck during live process. Without mechanical partial stroke tests, these critical on/off valves would have remained open upon request for an emergency shutdown.
Partial stroke testing
Netherlocks has received new EX certification for the Netherlocks FAITH partial stroke testing system, recognising the addition of a dedicated grounding means for the system.
Designed in response to customer demand, Netherlocks has developed the facility for entirely remote operation of our FAITH Partial Stroke Test (PST) system for ESD and HIPPS (Emergency Shut Down and High Integrity Pressure Protection System) valves.
