A recent trade record identifies 436887 as a “VALMET REPAIR SET – FDE STEEL EXCLUSIVE PART FOR VALVE” and records a shipment weight of 9 kg for one set. A separate recent procurement record identifies 436887 as a spare kit for a Metso pneumatic actuator.

Product Introduction

Architecture Hook

Metso 436887 is not an electronic control module. It is a mechanical service spare associated with a Metso pneumatic actuator, intended to restore the actuator’s mechanical sealing and operating condition without replacing the complete actuator assembly. Recent procurement documentation explicitly lists 436887 as a pneumatic-actuator spare kit, while trade data describes it as a steel repair set for a valve.

That distinction is important for asset control. A repair set has no meaningful firmware, processor revision, or electrical interface to verify; the critical records are the exact actuator model, valve assembly, kit contents, material specification, seal compatibility, and installation procedure. Metso’s own spare-parts catalog is installation-specific and is designed to identify parts by equipment structure, part number, and related bill of material.

🚨 Global Compliance & Industry Certifications

• CE Mark: A standalone CE claim for 436887 was not verified. Any CE documentation should be tied to the complete valve or actuator assembly where applicable.
• UL / cUL: No standalone UL or cUL approval was verified for the repair set.
• ATEX / IECEx: No standalone ATEX or IECEx certificate was verified. If the actuator operates in a hazardous area, the complete actuator/valve assembly and installation must satisfy the applicable hazardous-area requirements.
• Marine / DNV: No 436887-specific marine approval was verified.
• Pressure Equipment Compliance: If the repair set contains pressure-bound actuator components or sealing elements, applicable pressure-equipment requirements must be assessed at the complete actuator/valve assembly level.
• Material Traceability: Where the kit includes load-bearing or pressure-exposed metallic parts, retain material certificates or supplier declarations when required by the equipment specification.

The recent trade description explicitly refers to FDE steel, but this should be treated as shipment-description evidence rather than a substitute for a material certificate.

Verify specific lot certifications with OEM.

🚨 Long-Term Storage & Asset Preservation Guide

Keep the repair set sealed and dry. Mechanical kits often contain precision sealing surfaces, fasteners, and elastomeric parts that degrade differently. Do not open factory packaging merely to inspect individual components unless receiving inspection requires it.

Separate metal components from moisture-sensitive seals. If the kit includes O-rings, gaskets, diaphragms, or similar elastomers, preserve them in the manufacturer’s original packaging and away from direct sunlight, ozone-generating equipment, and excessive heat. Do not apply petroleum-based preservatives unless the specified seal material permits them.

Maintain warehouse humidity below 60% RH where practical. The reported FDE-steel construction makes corrosion control relevant, especially around machined threads and sealing interfaces. Desiccant is appropriate for long-term sealed storage, provided it does not contact elastomeric components directly.

Record the storage date and shelf-life status. Unlike an electronic card, the usable storage period may be controlled by elastomer age rather than the metal components. Obtain the actual Metso kit contents and applicable seal-storage limits before assigning an unrestricted shelf life.

Physical Installation Prerequisites

Install 436887 only into the specific Metso pneumatic actuator and valve assembly for which the kit is documented. The recent procurement record does not establish a universal actuator model for this part number, so substitution by visual similarity is not acceptable.

No reliable manufacturer-specific clearance, torque, pressure, or seal-compression values were established from the available public records. Those values must come from the applicable Metso actuator drawing and maintenance instructions.

Before disassembly, isolate the valve, shut off the pneumatic supply, release stored air pressure, and apply the site’s lockout/tagout procedure. If the actuator is connected to a process valve, verify the process side is isolated and safe before removing pressure-bound components.

Clean the actuator before opening it. Dirt introduced into the cylinder, piston, shaft seal, or valve interface can cause repeat leakage or premature wear even when every replacement component is new.

After installation, perform the manufacturer’s required actuator stroke and leakage checks. Where the actuator operates a process valve, verify the correct fail position and full travel before returning the equipment to service.

Buyer’s FAQ — Logistics & Compliance Focus

Q1. What HS tariff code should be used for Metso 436887?
Recent trade data shows 436887 shipped under HS code 84819000, with the description identifying it as a steel repair set for a valve. That is useful transaction evidence, but it should not be treated as a universal classification for every destination. Have the customs broker validate the destination-country tariff classification based on the actual kit contents and description.

Q2. Does the Metso part number establish the Country of Origin?
No. The part number identifies the Metso spare, not necessarily where each component was manufactured. The recent trade record shows a shipment originating from Germany to Chile, but shipment origin is not automatically manufacturing origin. Obtain a COO declaration tied to the actual lot or kit before making a preferential-origin claim.

Q3. Should shipping insurance be based on the reported 9 kg weight?
No. The 9 kg figure is a recent transaction weight for one set, useful for freight planning but not a substitute for the actual packed shipment weight. Record the actual gross weight, dimensions, declared value, and package condition before carrier pickup.

Q4. Does 436887 include the latest firmware pre-loaded?
No. This is a mechanical pneumatic-actuator repair set, not a programmable electronic module. The relevant compatibility checks are actuator model, valve assembly, component dimensions, seal material, pressure service, and installation procedure.

Q5. What documentation should procurement retain before the kit enters controlled spare inventory?
Keep the exact Metso 436887 identification, associated equipment reference, kit description, COO evidence, material documentation where applicable, supplier inspection record, shelf-life information for any elastomers, and receiving photographs. Metso’s installation-specific spare-parts approach should be used to confirm the part against the actual equipment structure before release to maintenance.
