9106160741 / 9106 1607 41 SEQUENCE VALVE ATLAS COPCO

If your drilling rig starts acting “out of order” even when everything looks normal on the surface, the issue is often hidden in the hydraulic logic. The 9106 1607 41 SEQUENCE VALVE ATLAS COPCO is one of those quiet components that doesn’t make noise, doesn’t draw attention, but can decide whether your machine feels sharp and responsive or sluggish and unpredictable.

This part is a cartridge-style hydraulic sequence valve built to manage pressure-dependent priorities inside a circuit. In rock drilling applications, sequencing is not a luxury. It’s what ensures one action completes (or reaches a set pressure) before the next action is allowed to happen. That’s how you protect pumps, stabilize drilling functions, reduce shock loads, and keep the rig behaving consistently shift after shift.

At 3GEN Export, we supply the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO as an OEM-grade solution for high-demand operations, with worldwide delivery in 5 working days.

What the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO does in a drilling hydraulic system

A sequence valve is a pressure-control component that “waits” until upstream pressure reaches a defined threshold, then opens a flow path to a secondary circuit. Think of it like a disciplined gatekeeper: it refuses to let the next operation steal energy until the first operation has secured the pressure it needs.

In heavy-duty drilling hydraulics, the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO is commonly used to:

Ensure correct order of functions (priority behavior)

Prevent premature movement that can cause vibration, overshoot, or mechanical stress

Smooth transitions between hydraulic events to reduce shock and heat

Help keep drilling performance predictable across temperature swings and load changes

Support stable operation during demanding duty cycles typical of underground and surface drilling

When a sequence valve drifts, sticks, leaks internally, or has tired seals, the system may still run—but it runs “out of rhythm.” That’s when operators notice delayed response, inconsistent feed/rotation behavior, pressure instability, or repeated nuisance faults.

Key identifiers: part numbers and search variations

To help your listing match more searches, it’s important to reference both formats:

9106160741 SEQUENCE VALVE ATLAS COPCO

9106 1607 41 SEQUENCE VALVE ATLAS COPCO

You’ll also see this component described as a cartridge sequence valve or hydraulic sequence cartridge depending on the parts list.

Construction details visible from the part design

From the product photos, the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO is a threaded, screw-in cartridge valve with:

A precision-machined steel spool section with metering ports

Multiple sealing rings (O-rings / backup rings) placed across key lands to isolate internal passages

A hex body section for torque application during installation/removal

A robust threaded section designed for valve block integration

This design is common in high-pressure, compact hydraulic manifolds, where multiple cartridge valves build the “logic” inside a valve block without requiring bulky external plumbing.

Why the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO matters for productivity

Downtime in drilling is rarely caused by one dramatic failure. More often it’s death by a thousand delays: slow cycles, inconsistent response, overheating oil, repeated resets, performance that fades after a few hours.

The 9106 1607 41 SEQUENCE VALVE ATLAS COPCO helps avoid those slow losses by keeping system behavior orderly. When sequencing is correct:

The rig behaves consistently across operators

Hydraulic energy is applied where it’s needed, when it’s needed

Shock loads reduce, protecting pumps, hoses, seals, and actuators

Heat generation falls because the system isn’t fighting itself

Wear on drilling components becomes more predictable

In other words, this valve supports operational “cleanliness”—not visually, but functionally.

Common symptoms of a failing sequence valve

If you’re troubleshooting, these signs often point to issues related to the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO (or the circuit it controls):

Delayed secondary function activation (one action starts too late)

Secondary function activates too early (order breaks)

Pressure hunts or fluctuates when a function is commanded

System feels weak under load even though pump/engine are healthy

Overheating oil, especially during repeated cycles

Intermittent performance that changes with oil temperature

Unexpected vibration or harsh engagement when a function “catches up”

Seal wear can also introduce internal leakage that’s hard to notice externally but easy to feel in performance.

Technical overview and practical specifications

Because sequence valves can be installed in different configurations and valve blocks, exact settings depend on the machine’s hydraulic design. That said, a robust drilling-grade cartridge like the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO is typically engineered around:

High-pressure hydraulic operation suitable for rock drilling duty cycles

Precision spool fits to reduce internal leakage and improve response

Seal systems designed to cope with pressure spikes and vibration

A threaded cartridge interface for valve block mounting

Stable flow behavior across common drilling oil temperatures

Typical data points to document on your internal spec sheet

When you’re confirming interchangeability, your maintenance team will usually check:

Thread type and cartridge cavity standard (valve block cavity)

Overall length, spool diameter sections, and sealing land locations

Number and position of O-rings / backup rings

Porting and flow direction behavior inside the manifold

Recommended torque range for installation (from the machine manual)

System pressure range and targeted sequence pressure setting (machine-specific)

If you want, you can share your valve block cavity reference or machine manual page, and I can help you create a tighter “verified” spec section for your listing.

Installation guidance for the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO

Replacing a sequence valve is straightforward, but success depends on cleanliness and seal discipline. A sequence valve is a precision hydraulic component. Any contamination can turn a perfect replacement into a repeat failure.

Recommended installation approach

1. Secure the machine and depressurize hydraulics
   Shut down, follow lockout steps, and relieve residual pressure. Never remove a cartridge under pressure.

2. Clean the surrounding area before removal
   Dirt around the valve block becomes dirt inside the valve block.

3. Remove the old cartridge carefully
   Use the correct tool on the hex body. Avoid rounding edges.

4. Inspect the cavity
   Look for scoring, debris, or damaged sealing surfaces. If the cavity is scratched, even a new 9106 1607 41 SEQUENCE VALVE ATLAS COPCO may not seal properly.

5. Replace seals correctly
   If your maintenance standard requires new seals each time, follow it. Lightly lubricate O-rings with clean hydraulic oil.

6. Install and torque to spec
   Do not overtighten. Cartridge valves seal via specific surfaces and seal geometry—excess torque can deform components.

7. Start and test in controlled steps
   Run the system at idle, check for leaks, then verify functional sequencing under load.

Maintenance tip that saves real money

Hydraulic oil cleanliness is not a slogan. It’s the real life expectancy multiplier. If sequence valves repeatedly fail early, the root cause is often contamination, filter bypass, or deteriorating hoses.

Where the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO is commonly used

This part number appears in Atlas Copco parts documentation tied to rock drilling hydraulic systems and drilling units.

In practice, the 9106 1607 41 SEQUENCE VALVE ATLAS COPCO is associated with:

Atlas Copco Boomer S1D (listed within parts documentation for its hydraulic system)

Atlas Copco COP 1838HD drilling unit documentation, where the sequence valve appears in the valve block parts list

Because drilling rigs often share hydraulic architecture across variants and production years, the same valve can appear across multiple configurations—especially when the machine uses the same valve block logic and drilling unit family. Always confirm by part number in your machine’s parts book before ordering.

The valve type is sequence (not relief, not counterbalance, not reducing)

The valve block cavity matches the cartridge geometry (length, seals, thread)

No prior “field modifications” changed the manifold configuration

If you’re unsure, send a photo of the installed valve location or your parts book line item. That’s usually enough to confirm quickly.

Operational value: what a correct sequence valve feels like

Operators don’t describe sequence valves in technical language. They describe the machine.

With the right 9106 1607 41 SEQUENCE VALVE ATLAS COPCO installed and the system healthy, the rig feels:

Predictable

Smooth under transitions

Stable under load

Less prone to sudden jolts or delayed engagement

Less sensitive to temperature-driven behavior changes

It’s the difference between a machine that “listens” and a machine that “argues.”
