Si decide comprar maquinaria a un precio inferior, póngase en contacto con el verdadero vendedor. Recopile toda la información que le sea posible sobre el propietario de la maquinaria. Una forma de engaño es presentarse como empresa. En caso de sospecha, infórmenos mediante el formulario de comentarios y sugerencias para que lo comprobemos.
Antes de confirmar una compra, revise detenidamente varias ofertas de venta para ver cuál es el precio medio del equipo elegido. Si el precio de la oferta que le interesa es mucho menor que el de ofertas similares, piénselo dos veces. Una diferencia de precio significativa puede conllevar a defectos ocultos o a un intento de fraude por parte del vendedor.
No compre productos cuyo precio diste mucho del precio medio de equipos similares.
No acepte compromisos dudosos o mercancías con prepago. Si no lo tiene claro, no dude en solicitar aclaraciones, pida fotos adicionales y documentos del equipo, compruebe la autenticidad de los mismos y pregunte todo lo necesario.
Esta es la forma más habitual de fraude. Ciertos vendedores pueden requerir una cantidad del pago por adelantado en concepto de «reserva» de su compra. Así, los estafadores perciben grandes cantidades de dinero y después desaparecen sin dejar huella.
- Transferencia de prepago a la tarjeta
- No realice un pago por adelantado sin documentación que confirme el proceso de transferencia de dinero, si durante la comunicación con el vendedor ha surgido alguna duda.
- Transferencia a una cuenta «fiduciaria»
- Dicha solicitud debe alarmarle, ya que en la mayoría de los casos se trata de fraudes.
- Transferencia a una cuenta de una empresa con un nombre similar
- Tenga cuidado, ya que los estafadores pueden ocultarse tras la identidad de empresas reconocidas, realizando modificaciones mínimas en su nombre. No transfiera dinero si tiene dudas sobre el nombre de la empresa.
- Sustitución de sus propios datos en la factura de una empresa real
- Antes de realizar una transferencia, asegúrese de que los datos especificados sean correctos y que aludan a la empresa en cuestión.

Product Overview
The Komatsu PC200‑6 is the late‑1990s predecessor to the ‑7 and ‑8 — a 20‑ton excavator from the generation that built Komatsu's reputation for hydraulic refinement. Its main control valve, OEM reference 72‑347‑13502, is the distributor that takes pump flow and routes it to boom, arm, bucket, swing and tracks. On a ‑6 that has worked through subdivisions, pipelines and road projects for decades, the valve is often the last major hydraulic component to be replaced — which means when it finally goes, the whole machine feels it.
Wear in a ‑6 valve announces itself the way old machines announce everything: gradually. The boom drifts down while holding a load, the bucket settles overnight, the swing becomes grabby on one side, and the tracks twitch when an attachment is cycled. Inside the block, worn spools and scored bores are bleeding oil across the lands. This OEM‑grade main valve replaces the whole assembly with fresh internals, set to the original Komatsu pressures, so the old block comes off and the new one bolts straight back on.
Core Advantages
1. Keeps a ‑6 generation machine earning
Original 72‑347‑13502 valves for the PC200‑6 grow scarcer as the fleet ages. This OEM‑grade assembly gives owners a dependable path to keep a still‑useful machine on the job.
2. Holds the boom where the operator leaves it
Drift under a loaded bucket is oil escaping past worn spool lands. Fresh spool‑and‑bore pairs restore the seal, holding position between lifts and cutting constant re‑spotting.
3. Swing control returns for precise spotting
Scored bores make the house sloppy — overshoot, then a hunt back. Lapped spools restore clean metering, so the operator can spot the bucket against a truck body without fighting the machine.
4. Tracks and attachments stop stealing flow
The distributor sets priority between travel and working circuits. New internals put that order back to Komatsu's design, ending the surge when the bucket is cycled and the tracks grab.
5. A complete block beats a bench rebuild on an old machine
Re‑spooling a worn ‑6 valve is delicate, hours‑long work. Swapping in this tested assembly is one clean exchange with the same hose positions — the practical choice on a high‑hour excavator.
Manufacturing & Quality Control
The OEM‑grade route follows controlled specifications: material certification, precision finishing of spool and bore pairs, and clean assembly. Each completed valve is run‑in on the bench and flow‑tested across its circuits, with relief and compensator settings logged before acceptance; anything off spec is stripped and reworked. The finished block is oil‑fogged, port‑plugged and crated on shock‑absorbing dunnage.
Frequently Asked Questions
Q1: How do I confirm 72‑347‑13502 matches my PC200‑6?
A: Read the tag on your existing valve and send the machine serial number. Komatsu build variants across the ‑6 run can differ, so we cross‑check before dispatch.
Q2: Is this the same valve as the PC200‑7 or ‑8?
A: No — the ‑7 and ‑8 generations use a different distributor with updated porting and pressures. The generations are not interchangeable without major plumbing changes.
Q3: What symptoms point to valve wear?
A: Boom drift, bucket settle at idle, grabby or overshooting swing, and tracks that surge when attachments are cycled. A leak test will confirm before you commit.
Q4: Can my existing valve be repaired?
A: Often yes — if the block casting is sound, a re‑spool and seal kit can restore it. Send photos and we will advise honestly on repair versus replacement.
Q5: What else should be serviced at the same time?
A: The hydraulic oil and filters. Flush the circuit and change the return filter and suction strainer so the new spools run in clean oil from day one.
Q6: What voids the warranty?
A: Materials and build defects are covered. Damage from contaminated oil, water ingress, a seized spool forced into movement or incorrect pressure adjustment is excluded. Photograph any arrival damage before uncrating
