Used Hydraulic Distributors for Volvo Machinery

72 produits disponibles

The hydraulic distributor is the central component in the pressure circuit of your Volvo construction machines: it directs the oil flow to the arm, bucket, or boom cylinders, as well as to the rotation motors, according to the operator's commands. A worn or faulty distributor causes cylinder drift, imprecise boom movements, or a loss of power throughout the circuit. At Codimatra, a supplier of spare parts for construction equipment for over 40 years, you will find used Volvo construction hydraulic distributors sourced from carefully selected machines, dismantled and tested in our workshop before shipment.

Volvo Construction Equipment: Reliable Hydraulic Systems On Site

Volvo Construction Equipment (Volvo CE) develops and markets hydraulic excavators on tracks and wheels, wheel loaders, dump trucks, and compactors present on construction sites across Europe and worldwide. The hydraulic systems equipping these machines are designed for high pressures and flow rates, with main sectional block valves allowing simultaneous control of several actuators during the work cycle.

Volvo Construction Equipment is part of the Volvo AB group, headquartered in Sweden. The construction equipment division is separate from Volvo Trucks (road vehicles) and Volvo Cars: Volvo CE machines use specific hydraulic components that are not interchangeable with those of other Volvo group branches.

The existing fleet of Volvo CE machines in operation in France is significant. This facilitates the availability of used Volvo construction hydraulic distributors from recent dismantlings, offering an economical parts solution adapted for construction professionals.

Types of Hydraulic Distributors on Volvo Construction Machines: Supplier of Volvo CE Parts

Volvo CE construction machines employ various distributor configurations depending on machine type and year of manufacture.

  • Main sectional block distributor: the standard configuration on Volvo hydraulic excavators. Each section controls an actuator (left translation, right translation, arm, bucket, boom, rotation). The number of sections varies by model.
  • Double-acting distributor: a universal configuration on Volvo CE excavators for active movements in both directions (arm, bucket, boom).
  • Single-acting distributor: used on some attachments and auxiliary equipment for Volvo excavators and wheel loaders.
  • Electrohydraulic distributor: found on recent Volvo CE models with pilot-controlled joysticks, especially on EC and ECR series from 2010-2015 onward.
  • Distributor for Volvo wheel loaders (L60, L90, L110, L150): a configuration specific to the lifting and bucket tilt circuits.

How Does the Main Distributor Work on a Volvo Excavator?

The main distributor receives high-pressure oil from the pump outlet and distributes it among the different actuators via sliding spools housed within its body. On a Volvo hydraulic excavator, each spool controls a specific movement: translation, turret rotation, arm, bucket, boom. In neutral position, the spool allows free flow or blocks oil circulation depending on the configuration.

The notation 4/3 indicates 4 ways (two outputs to the actuator, one pump input, one tank return) and 3 spool positions (forward, neutral, reverse). On Volvo distributors, the central neutral position may provide free circulation (cross position) or blockage depending on the function concerned. The cross position is common on translation circuits to allow stopping under load without blocking the pump.

A worn main distributor on a Volvo construction excavator manifests as uncommanded boom or arm movements (load drift), abnormal slowness on a precise movement, or pressure loss over the entire circuit. Diagnosis is confirmed by measuring pressure at distributor ports before removal.

Used Volvo Hydraulic Distributor: A Cost-Effective Solution to Reduce Operating Expenses

For construction professionals, the cost of a new main distributor for Volvo CE machines is a significant investment. A used Volvo construction hydraulic distributor, inspected and tested in our workshop, provides a reliable alternative to return an immobilized excavator or wheel loader to service while controlling the operating costs of your fleet.

  • Volvo tracked excavators (EC140, EC160, EC210, EC240, ECR145EL, ECR235DL): main sectional block distributors are highly demanded for these widely used second-hand models
  • Volvo wheel loaders (L60H, L90H, L110H, L150H): the lifting and steering distributors are the most commonly replaced parts
  • Volvo wheeled excavators (EW160, EW180): a mixed configuration with a specific translation distributor for hydrostatic transmission
  • Other Volvo CE equipment: upon request, our teams identify the appropriate reference using your machine’s model and serial number

Volvo Construction Hydraulic Circuit: Components Associated with the Distributor

The hydraulic distributor operates directly in concert with other pressure circuit components of your Volvo machine.

The Volvo construction hydraulic rotation motor is powered through the distributor’s rotation section. Wear of this section's spool can mimic a failure of the rotation motor itself: always compare pressures on both components before any dismantling.

The translation motor reducer also draws supply from the distributor’s translation sections. Sluggish movement on flat ground may indicate insufficient flow at the distributor before signaling motor reducer wear.

A hydraulic distributor receives high-pressure oil from the pump outlet and directs it to the actuators (cylinders, hydraulic motors) by moving internal spools. The position of the spool determines the direction of the oil flow and thus the direction of the actuator's movement. On Volvo hydraulic excavators, the main distributor combines several independent sections, each controlling a machine function (boom, arm, bucket, rotation, translation).

The 4/3 notation refers to a distributor with 4 ways and 3 positions. The 4 ways correspond to the distributor’s hydraulic connections: pump input (P), tank return (T), and the two outputs to the actuator (A and B). The 3 positions relate to the spool states: movement in one direction, neutral, movement in the opposite direction. On Volvo CE distributors, the central neutral position can be either free-flow or blocked, depending on the controlled function.

Volvo Construction Equipment is the construction division of the Swedish Volvo AB group. Its hydraulic excavators originated from the 1995 acquisition of Samsung Heavy Industries’ construction equipment division, which already manufactured excavators based on technology developed with Volvo. Volvo CE excavator production plants are mainly located in South Korea, China, and Poland. Volvo CE machines are independent of Volvo Trucks (road vehicles): their hydraulic components, including distributors, are not interchangeable between the two product lines.

Hydraulic distributors are mainly distinguished by their spool configuration (single-acting or double-acting), number of ways and positions (4/2, 4/3, 6/3, etc.), and control type (manual, electrohydraulic, proportional). On Volvo Construction Equipment machines, the main distributor is typically a sectional block with electrohydraulic control on recent models, or mechanically operated on generations prior to roughly 2005.
