Solution safety valve prevent shutdown

Pilot operated safety relief valve with high maintenance frequency due to limited lifetime of some internal parts. The challenges was large fluctuating process pressure pulses and process pressure very close to set pressure.
Any maintenance required plant shut down of the actual production line.

The manufacturer BHGE Consolidated developed a solution together with the customer based on well proven and existing pilot operating safety relief valve equipment. Consisting of a dual pilot safety valve with a second pilot onto the same main valve assembly and a twin diverter valve to direct the flow through each valve as required, using a manual changeover handle.

This solution allow continuous operation with live changeovers of the pilots, allowing maintenance on one of the pilot valves when needed.
Two complete valve assemblies were ordered and mounted on each of the main production lines.
