Valve bodies, manifold cores and blind-mate shells machined in-house on 3-, 4- and 5-axis centers — sealing faces ground to a ±0.01 mm tolerance and bores held from DN03 to DN10, in 316L stainless, brass or aluminum.
A dry-break coupling seals at two metal valve seats and one elastomer ring. If seat geometry drifts, no compound rescues the leak — so DryLink seats are ground, not turned, to a ±0.01 mm tolerance, and ball-contact hardness is held at the 24 HRC minimum the OCP UQD specification sets for the sealing interface.
Bore accuracy is flow accuracy. The dash-04 class needs a 7.14 mm minimum orifice to deliver its 0.80 Cv and 1.7 GPM rating — machining that drifts a few hundredths of a millimetre taxes every litre the loop moves.
The numbers below are the ones incoming inspection at your end can check first — bring a CMM and a gauge set and audit any batch against this window.
| Capability | Window / Value | Applied to |
|---|---|---|
| Machining axes | 3-axis / 4-axis / 5-axis centers | valve bodies, manifold bores, angled ports |
| Valve-seat tolerance | ±0.01 mm, ground finish | sealing faces on UQDB and UQ04 sets |
| Bore range | DN03 – DN10 | coupling flow paths and manifold branches |
| 1U envelope | 44.45 mm pitch height | board-level UQD hardware per OCP layout |
| Orifice control | 7.14 mm minimum on dash-04 | holds Cv ≥ 0.80 at the 1.7 GPM class |
| Ball-contact hardness | 24 HRC minimum | OCP floor for the dry-break sealing interface |
| Body materials | 316L stainless / brass / aluminum | chosen per loop chemistry and cost target |
| Threaded ends | ORB stud ends to ISO 11926-3 | -04 / -06 / -08 plug interfaces |
| First article | FAI with full CMM dimension report | every new part number before volume |
| Batch size | MOQ 50 pieces | production and pilot builds alike |
| Standard lead time | 15 days ex-works | catalog UQD sets after drawing freeze |
| DFM turnaround | 48 hours | annotated feedback on customer drawings |
Body alloy decides corrosion behavior, machinability and cost in that order. We keep all three on the shelf so the choice follows your coolant — not our convenience.
The default valve-body alloy for liquid cooling. 316L stands up to glycol-loop corrosion and is qualified against deionized water, water-glycol mixtures and fluorinated fluids — one material covering the coolants data centers actually run.
Chosen where multi-port manifold cores and threaded ports need fast, clean chip formation and stable thread quality. Lead-controlled supply keeps copper-alloy parts inside the RoHS 6/c machining exemption — at or below the 2.2% lead level disciplined suppliers target.
Used for weight-critical brackets, housings and structure around the loop where the coolant never wets the part. Anodized finishes are verified in 48 hours of neutral salt spray per ISO 9227 before a surface recipe is released to production batches.
Port maps, tight envelopes or a failed sample — MOQ from 50 pieces and a 15-day standard lead time make pilots cheap to try.
