ATEX certification
27 January 2014
Netherlocks has received new EX certification (CE Ex II 2 G D c IIC T4) for the Netherlocks FAITH Partial Stroke Testing (PST) system, recognising the addition of a dedicated grounding means for the system.
The FAITH PST device uses mechanical pins to limit the degree of valve closure, allowing for easy, safe testing of system-critical components such as ESD (Emergency Shut Down) and HIPPS (High Integrity Pressure Protection System) valves without affecting normal online process or operation.
There is no risk of test angle overshoot or process interruption, the test can be performed at ‘real’ speed and will always return results.
