Description
The Metso A413325 is a high-performance smart valve positioner engineered for Metso’s Neles®and Jamesbury®control valves—critical components in process industries like mining,oil&gas,and chemical manufacturing.Serving as the”precision control center”for valves,it converts digital/analog control signals into mechanical motion to adjust valve stem position,ensuring accurate flow regulation of slurries,gases,and corrosive fluids.Built to withstand harsh industrial conditions,this positioner delivers 0.1%control accuracy,IP67 environmental protection,and integrated predictive diagnostics,ensuring reliable valve operation in remote mining sites,offshore platforms,and pulp mills where valve failure can cause costly process shutdowns.
Application Scenarios
A South American copper mine faced recurring issues with its slurry valve control:legacy positioners(0.5%accuracy)caused inconsistent ore flow,leading to 3-4 separator overloads monthly(each costing$40,000 in downtime).After upgrading to Metso A413325 positioners on 18 Neles®control valves,the mine achieved transformative results.The positioner’s 0.1%accuracy stabilized slurry flow,while its IP67 rating withstood dust and water ingress in underground processing areas.Over 12 months,separator overloads dropped to zero,ore processing efficiency rose by 7%,and maintenance visits to remote valves fell by 60%—proving A413325’s value in harsh mineral processing environments.

Technical Principles and Innovative Values
Innovation Point 1:Ultra-Precise Control(±0.1%)–Unlike standard positioners(±0.5%accuracy),the A413325 uses a dual-sensor feedback system to adjust valve position with sub-millimeter precision.A chemical plant used this capability to regulate acid flow in pH control loops,reducing pH deviation by 80%and minimizing product waste.
Innovation Point 2:Predictive Valve Health Monitoring–The positioner logs stroke time,air consumption,and friction levels,alerting maintenance teams to incipient valve wear(e.g.,stem seal degradation)4-6 weeks before failure.An oil refinery avoided 2 unplanned shutdowns by replacing valves proactively,saving$250,000.
Innovation Point 3:Harsh Environment Durability–With IP67 protection and-40°C to+85°C temperature range,it outperforms positioners limited to IP65/0-60°C.A Canadian mining operation used A413325 in-35°C winter conditions without heating,saving$3,000 yearly per valve in energy costs.
Innovation Point 4:Seamless Protocol Integration–Supporting HART 7 and Profibus PA,it connects directly to DCS systems(e.g.,Emerson DeltaV,Siemens PCS7)without converters.A pulp mill reduced integration costs by$12,000 by eliminating third-party protocol gateways.
Application Cases and Industry Value
Case 1:Mining Slurry Valve Control
A Western Australian iron ore mine integrated Metso A413325 positioners on 24 Neles®segment valves controlling slurry flow to crushers.Legacy positioners failed every 6-8 months due to dust and vibration,causing 2-3 crusher overloads monthly.The A413325’s IP67 rating and vibration tolerance eliminated failures,while its 0.1%accuracy stabilized slurry flow.Over 18 months,valve maintenance costs fell by 75%,crusher downtime dropped by 90%,and ore production increased by 5%—delivering a full ROI in 4 months.
Case 2:Chemical Plant Corrosive Fluid Regulation
A European chemical plant deployed Metso A413325 on 16 Jamesbury®ball valves handling hydrochloric acid(HCl)flow.Previously,positioners with plastic housings degraded within 12 months,leading to acid leaks and safety risks.The A413325’s corrosion-resistant aluminum housing and Viton®seals withstood HCl exposure,extending service life to 5+years.Its predictive diagnostics also detected a failing valve seat 5 weeks early,allowing scheduled replacement during a maintenance window—avoiding a potential$150,000 environmental cleanup.
