Powerflo’s valve aftermarket service program offers complete services specialising in: pressure relief and control valves; as well as, pressure/vacuum vents, flame/detonation arrestors and waste gas burners. Services include on-site installation, start-up, predictive and preventative maintenance programs, equipment testing, calibration, rebuilding and trouble-shooting, and complete shutdown valve/instrument turnaround management. The program also includes on-site testing, field retrofitting, and hands-on training.

We also provide professional repair service as standard from one valve to complete plant shutdowns. This includes the complete overhaul of the relief/control valve, actuator and instrumentation. The assemblies are fully disassembled, inspected, reassembled, calibrated and tested to meet Australian and relevant industry standards. All soft goods are replaced within this process. Valve assemblies can be repainted prior to returning to service.
