Remote valve testing: Netherlocks USA

Dec. 1, 2012
Netherlocks Faith Partial Stroke Test system can now remotely conduct online tests of emergency shutdown (ESD) and high integrity pressure protection system (HIPPS) valves. Operators can reduce degradation and ensure the proper operation of emergency valves from the safety of the control room. The system uses a simple design for reliable operation and integrates into a valve's static and dynamic couplings. Its mechanical steel blocking pins ensure that valves cannot be operated past the preset test angle to eliminate the risk of overshoot or process interruption. Netherlocks
