3222306267, 3222 3062 67 RELIEF CARTR ATLAS COPCO

If your drill rig’s hydraulic circuit is the “nervous system,” then a relief cartridge is the reflex that prevents damage when pressure spikes hit. The 3222306267 part number—also searched as 3222 3062 67—is a cartridge-style pressure relief component built for Atlas Copco rock drilling applications where stable pressure control and system protection are non-negotiable.

This page is written for buyers, technicians, and maintenance teams who need a clear, practical understanding of what the 3222 3062 67 RELIEF CARTR ATLAS COPCO does, how it behaves in the circuit, what to check during installation, and how to keep the machine running efficiently. We supply this part as 3GEN Export, an OEM supplier, with worldwide delivery in 5 working days.

What the 3222 3062 67 RELIEF CARTR ATLAS COPCO actually does

A relief cartridge is designed to protect a hydraulic circuit by limiting maximum pressure. When system pressure rises beyond a set threshold, the valve opens and diverts flow to a return path—preventing damage to pumps, hoses, manifolds, and downstream components.

In real drilling conditions, pressure spikes can happen fast:

• Cold oil at startup increases resistance and pressure.

• A sudden load change (bit binding, feed force change, rotation resistance) causes instantaneous pressure peaks.

• Contamination or a restricted return path can create unstable pressure behavior.

• Over-tightened settings after service can push the system beyond safe limits.

In these moments, the 3222 3062 67 RELIEF CARTR ATLAS COPCO is the component that absorbs the shock and stabilizes the circuit before that spike becomes a pump failure or a burst hose.

The 3222 3062 67 RELIEF CARTR ATLAS COPCO is typically used in a hydraulic manifold (or valve block) where it can respond quickly, maintain repeatability, and be serviced without replacing the entire manifold.

Why cartridge-style relief valves are used in rock drilling equipment

Rock drilling rigs demand compact, modular, high-response hydraulics. Cartridge valves are favored because they:

• Fit directly into a valve block, saving space.

• Reduce external plumbing, which reduces leak points and vibration-related fatigue.

• Enable fast maintenance: remove, replace, torque, test.

• Offer consistent performance when correctly installed and kept clean.

That’s why the 3222 3062 67 RELIEF CARTR ATLAS COPCO is engineered as a cartridge design—built to operate in harsh, dusty, vibration-heavy environments while supporting high-duty cycles.

Key benefits of the 3222 3062 67 RELIEF CARTR ATLAS COPCO in the field

Even though it looks small compared to other rig components, a relief cartridge influences uptime more than most buyers expect. The 3222 3062 67 RELIEF CARTR ATLAS COPCO helps deliver:

• Protection of expensive components (pump, motor, valve block, hoses, seals)

• Pressure stability, which improves drilling consistency and reduces operator “hunting”

• Reduced heat generation, because the circuit avoids continuous overpressure and bypass

• Lower maintenance cost, by preventing cascading failures

• More predictable performance, especially under variable load conditions

When the 3222 3062 67 RELIEF CARTR ATLAS COPCO is operating correctly, you typically see fewer pressure alarms, fewer blown seals, and smoother machine response—especially during heavy drilling or aggressive feed settings.

Product identification: use both codes for search and purchasing

Customers look up this item in different formats. To match procurement systems and technician habits, keep both in your records:

• 3222306267

• 3222 3062 67

• 3222 3062 67 RELIEF CARTR ATLAS COPCO

• “Relief cartridge 3222306267 Atlas Copco”

For RFQs and internal stock control, it’s best to include both the continuous number (3222306267) and the spaced format (3222 3062 67) to avoid delays.

Construction and design details

From the images, this is a robust, precision-machined assembly designed for manifold installation. Typical construction features for a component like the 3222 3062 67 RELIEF CARTR ATLAS COPCO include:

• Hardened steel internal moving elements to withstand repeated cycling

• High-quality sealing rings to prevent internal leakage and pressure drift

• Machined threads and shoulders for stable seating in the valve block

• Stable adjustment behavior (depending on the circuit design and configuration)

A relief cartridge must balance two things at once: open quickly during a spike, and close smoothly without causing oscillation. That stability is critical on rigs that run long drilling cycles where temperature changes, vibration, and load variation are constant.

Where the 3222 3062 67 RELIEF CARTR ATLAS COPCO is commonly used

In most Atlas Copco drilling hydraulics, relief cartridges can be assigned to protect different circuit branches, such as:

• Feed circuit protection (prevent overloading feed cylinders/motors)

• Rotation circuit protection (limit torque-related pressure spikes)

• Auxiliary circuit protection (clamps, stabilizers, positioning functions)

• General manifold protection to keep the valve block within safe pressure limits

Because exact placement depends on the rig version, hydraulic diagram, and serial range, technicians usually identify the location by the manifold designation and the exploded parts list.

Compatible Atlas Copco models that commonly reference this part

Based on available spare parts listings and catalog references, the 3222 3062 67 RELIEF CARTR ATLAS COPCO is commonly referenced for rigs in the ROC family, including listings for ROC L8 and references that also point to other ROC-series configurations.

Practical fitment guidance:

• Atlas Copco ROC L8 (commonly referenced in spare parts listings)

• ROC-series drilling rigs where the same manifold/circuit is used (verify by parts manual and machine serial)

Important note for procurement teams: “Model compatibility” in drilling equipment is often serial-dependent. Two machines with the same model name can have different valve blocks depending on production year, upgrade kits, and regional configurations. The safest workflow is:

• confirm 3222306267 / 3222 3062 67 in the machine’s parts manual, or

• match the removed cartridge’s markings and measurements, or

• share your machine serial and the manifold code with us for confirmation.

Technical specifications (practical, field-focused)

Exact numeric settings vary by circuit and rig configuration, but technicians typically care about these characteristics when evaluating a relief cartridge:

Operating role

The 3222 3062 67 RELIEF CARTR ATLAS COPCO functions as a pressure-limiting element that opens when the circuit exceeds its intended pressure ceiling.

Interface and installation style

• Cartridge body designed to seat into a valve block/manifold

• Threaded insertion with sealing surfaces and O-rings

• Requires correct torque to avoid leakage or distortion

Sealing

• O-ring sealing is critical; damaged seals can cause internal leakage, pressure drift, and heat buildup

• Clean installation prevents O-ring cutting and seat damage

Response behavior

• Should open quickly during spikes

• Should not “chatter” during stable operation

• Should return to closed state smoothly

If a machine shows fluctuating pressure or unstable function under constant load, the relief cartridge and related circuit cleanliness are among the first components to inspect.

Installation guide for technicians

Below is a technician-friendly procedure to install or replace the 3222 3062 67 RELIEF CARTR ATLAS COPCO.

1) Safety and depressurization

• Shut down the machine fully

• Follow lockout/tagout procedures

• Bleed pressure from the hydraulic circuit according to the service manual

• Allow oil temperature to drop if the machine was running hot

2) Remove the old cartridge

• Clean the manifold area thoroughly before removal (avoid pushing dirt into the block)

• Use the correct tool on the hex body

• Remove slowly and observe any oil flow (residual pressure can remain)

3) Inspect the port and seat

• Check for scoring, burrs, or debris in the manifold cavity

• Inspect the removed component for metal particles, seal damage, or unusual wear patterns

4) Install the new cartridge

• Lightly lubricate O-rings with clean hydraulic oil

• Seat the cartridge by hand first to prevent cross-threading

• Torque to spec per the service manual (do not over-tighten)

5) Test under controlled conditions

• Start machine at idle

• Watch for leakage around the port

• Verify pressure behavior during function tests

• Confirm stability under normal operating load

A correctly installed 3222 3062 67 RELIEF CARTR ATLAS COPCO will keep pressure peaks controlled without turning the system “lazy” or overheating during normal operation.

Common failure symptoms and what they usually mean

When the 3222 3062 67 RELIEF CARTR ATLAS COPCO begins to drift out of spec, the rig often “tells you” in predictable ways:

Symptom: pressure won’t build, weak function

Possible causes:

• Internal leakage through the cartridge

• Damaged seal(s)

• Debris preventing full closure

• Worn internal elements

Symptom: pressure spikes, harsh response, hose stress

Possible causes:

• Cartridge stuck closed or slow to open

• Contamination restricting movement

• Incorrect installation or damaged seat

Symptom: overheating and constant bypass behavior

Possible causes:

• Relief opening too early (drift)

• Internal leakage creating continuous flow loss

• Circuit misadjustment or wrong cartridge for the port

Symptom: chatter / oscillation

Possible causes:

• Air in the system

• Incorrect oil viscosity

• Contamination

• Worn valve block cavity or unstable circuit conditions

When any of these appear, replacing the 3222 3062 67 RELIEF CARTR ATLAS COPCO is often a cost-effective first corrective step—especially if the removed unit shows evidence of contamination or seal damage.

Maintenance tips to extend service life

Relief cartridges live and die by oil cleanliness and stable operating conditions. To extend the life of the 3222 3062 67 RELIEF CARTR ATLAS COPCO:

• Maintain hydraulic oil cleanliness targets (filter changes on time)

• Avoid mixing oil types that can affect seal behavior

• Warm the machine properly in cold climates

• Monitor for recurring contamination (if contamination repeats, investigate root cause)

• Keep manifold ports protected during service work

If you’re replacing multiple cartridges frequently, it’s usually a sign of filtration issues, system wear, or poor service cleanliness—not the cartridge design itself.
