3. Threads and JINGYE Dimensions
UQDB02: 7/16-20 UNF-2A or G1/8 BSPP; A/B/C = 36.0/27.0/21.0 mm; HEX 19 mm.
UQDB04: 9/16-18 UNF-2A or G1/4 BSPP; A/B/C = 45.4/35.4/25.0 mm; HEX 23 mm.
UQDB06: 3/4-16 UNF-2A or G3/8 BSPP; A/B/C = 50.9/38.9/28.4 mm; HEX 27 mm.
UQDB08: 7/8-14 UNF-2A or G1/2 BSPP; A/B/C = 56.9/42.9/31.0 mm; HEX 29 mm.
A/B/C follow JINGYE drawings; verify port seals and mounting envelope.
4. Pressure and Temperature
JINGYE Catalog Working Pressure: 0 ~ 100 psi (0 ~ 6.9 bar).
JINGYE Catalog Operating Temperature: -55°C ~ +125°C, depending on seal, coolant and configuration.
Burst and qualification ratings: Per selected plug/socket tests.
System limits depend on the lowest-rated component.
5. Blind-Mate Alignment and Mating Force
Design: Axial travel, radial/angular offset, guide geometry, connection/withdrawal force and vibration.
Industry UQDB designs may accommodate 1 mm radial offset; verify JINGYE pair and mounting tolerances.
Mating forces and cycles are evaluated on the assembled pair.
6. Flow, Pressure Drop and Coolant Loss
Flow Evaluation: Coupled-pair Cv, pressure drop versus flow rate, coolant viscosity and flow direction.
Leakage: Coupled/uncoupled leakage, per-cycle fluid loss and air inclusion.
Flow and loss differ by UQDB size. Qualify actual Cv, loss and burst ratings; do not reuse UQD values.
7. Materials, Seals and Fluids
Standard Body: SUS304 stainless steel; optional SUS316L.
Sealing Materials: Peroxide-cured EPDM or FKM (Viton), according to fluid and temperature compatibility.
Typical Coolants: Deionized water, propylene glycol/water (PGW), ethylene glycol/water (EGW), and qualified single-phase coolant mixtures.
Salt Spray Resistance: 96 hours according to JINGYE series catalog.
Check additives, corrosion, seal swelling and cleanliness.
8. Durability and Quality Inspection
Quality Management: ISO 9001:2015.
JINGYE series lists 5,000 mating cycles; validate the selected pair and conditions.
Inspection: Mating profile, valve travel, flat-face sealing surfaces, threads, dimensional tolerances, surface cleanliness and visual condition.
Qualification: Helium leaks, cycling, thermal, pressure, flow and alignment.
9. Manufacturing and OEM Support
Precision CNC production with optional end connections, materials, sealing compounds, drawings, samples and inspection documentation.
OEM inputs: Mounting, guides, misalignment, axial travel, insertion force and mating socket.
Second source: Dimensional comparison, cross-mating and testing.
