Pilot operated safety valve with high maintenance frequency due to limited lifetime of some internal parts.
The challenges were large fluctuating process pressure pulses and process pressure very close to set pressure.
Maintenance of the safety valve required a shutdown of the relevant production line.
Manufacturer BH Consolidated worked with the customer to develop a solution based on a well-proven and existing pilot-operated safety valve.
Consisting of a double pilot operated safety valve on the same unit and a shuttle valve to direct the flow through each pilot valve as required using a manual shuttle handle.
This solution enables continuous operation with shuttering between pilots.
Where one of two pilots on the safety valve can be removed for maintenance.
Two complete valve units were ordered and installed on each of the main production lines.
