Maxon offers a unique approach to valve diagnostic testing with PSTrend, its patent-pending technology which reduces probability of failure on demand (PFD) without line shutdown or having to bypass any burner management safety functions. The PLC-based system pulses power to the valve solenoid, resulting in partial movement of the valve disk, recording and trending that data to show a dangerous, undetected failure state which could result in a catastrophe. The valuable information provided by PSTrend helps operators maintain agency- and standards-mandated valve performance over time while also allowing for predictive maintenance cycles. Regular testing with PSTrend can increase process safety and lead to an operation's increased uptime.
