What This Valley IV Factory Setup Produces

This Arknights Endfield Valley IV factory setup focuses on the most common mid-game bottleneck: capsules and batteries competing for ore.

Final Production Outputs

Capsule / Citrome A
Capsule C
HC Batteries
LC Batteries

This combination covers:

Progression requirements
Stable battery demand
Long-term Valley IV efficiency

Why This Is an Optimized Valley IV Factory

Many Valley IV layouts fail because they:

Overproduce batteries
Waste Amethyst
Starve Ferrium for Capsule A

This setup avoids those problems by fully respecting Valley IV ore caps while keeping all production lines active.

Valley IV Ore Usage Breakdown (Fully Optimized)

Originium (≈ 560/min cap)

HC Batteries: 180/min
LC Batteries: 360/min
Total: 540 / 560 used

Amethyst (≈ 240/min cap)

Capsule C: 60/min
LC Batteries: 180/min
Total: 240 / 240 used (perfect cap)

Ferrium (≈ 1080/min cap)

Capsule / Citrome A: 960/min
HC Batteries: 120/min
Total: 1080 / 1080 used (fully capped)

This is what players mean when they search for an optimized Valley IV factory in Endfield—maximum output, zero waste.

MainPAC vs SubPAC Layout Guide (Valley IV)

To avoid import issues and belt misalignment, use this structure:

MainPAC

Acts as the battery production core
Handles HC and LC Battery blueprints
Centralizes depot output

SubPACs

Dedicated zones for:
- Capsule / Citrome A
- Capsule C
Keeps high Ferrium and Amethyst demand isolated

Placement Tips

Position Capsule A blueprints on the right or upper-right side
Align depot buses before importing
Rotate blueprints instead of forcing conveyors

This layout is optimized specifically for Valley IV MainPAC and SubPAC interaction.

How to Import Valley IV Blueprint Codes

If you’re new to shared blueprints in Endfield:

No manual rebuilding required.

Common Valley IV Factory Mistakes (And How This Fixes Them)

❌ Overcapping Amethyst
❌ Running Capsule A without enough Ferrium
