ASM SIPLACE 03058802 is the digital pressure control valve used in the TwinHead pneumatic system. This part has a stronger service identity than the market alias TH Generator because the TwinStar service documentation defines it specifically as the TwinHead digital PRV.
Its most important application is the documented analog-to-digital PRV retrofit path. The service manual requires a TwinHead head-board function state of at least 09, and conversion from the older analog PRV is handled through a dedicated retrofit instruction.

03058802 TwinHead Digital PRV
| Part Number | 03058802 |
| Documented Reference | 03058802-02 / 03058802-xx |
| Part Type | Digital pressure control valve |
| Head Application | TwinHead family |
| Retrofit Use | Analog PRV to digital PRV conversion |
| Head-Board Requirement | Function state 09 or higher |
| Decision Point | Confirm current valve type and head-board function state before retrofit |
This makes 03058802 fundamentally different from an ordinary like-for-like valve replacement. On a TwinHead still equipped with the analog pressure-control system, the correct decision is a retrofit assessment rather than simply fitting the digital valve because the connection appears compatible.
If the machine already uses the digital PRV, diagnosis should follow the pressure-control path: air supply, filter, pneumatic connections and valve operation should be checked before assigning the fault to the 03058802 assembly itself.
