Plant diagnostic technology that overcomes the uptime–safety dilemma, evolving into predictive maintenance
Valmet has deployed 50 Neles ValvGuard PST online diagnostic devices at Lotte Chemical’s Daesan petrochemical plant, enabling continuous monitoring and testing of critical emergency shutdown (ESD) valves without interrupting production. By combining partial stroke testing with real-time diagnostics, the solution helps detect potential issues earlier, improve safety and reliability, reduce unplanned downtime, and support the shift from scheduled maintenance to data-driven predictive maintenance.
