Precision Wax Moulding

DELCO VALVE’s advanced wax injection process crafts valve patterns with ±0.5°C thermal control and ≤0.1mm dimensional precision. Robotic assembly creates multi-component "wax trees" for ceramic shell coating, enabling intricate superalloy casting. Post-dewaxing yields molds achieving Ra 1.6μm surface finishes, ideal for high-pressure sealing surfaces.

Heat Treatment Process

Post-cast valve components undergo controlled heating in computerized furnaces (1050°C ±10°C) for solution annealing, followed by rapid quenching in polymer solutions. Stress-relief tempering at 600°C achieves HRC 20-24 hardness in ASTM A351 CF8M stainless steel. DELCO VALVE’s nitrogen-atmosphere chambers prevent oxidation, ensuring uniform microstructure for sour service.

High-Efficiency Material Removal

5-axis CNC mills remove 85% of excess material from cast blanks at 15,000 RPM. DELCO VALVE’s adaptive toolpaths maintain ±0.25mm tolerance on pre-machined bodies. Carbide inserts with TiAlN coatings enable 300+ hour tool life when processing super duplex steels.

Precision Drilling

Deep-hole gun drilling machines create ±0.05mm bore accuracy in valve stems. DELCO VALVE uses MQL (Minimum Quantity Lubrication) technology for 8D-20D aspect ratio holes. Real-time torque monitoring prevents work hardening in Inconel 625 trims.

Zero-Compromise Quality Assurance

Hydrostatic shell tests at 1.5x MAWP (per API 598) followed by helium mass-spec seat tests (≤1×10⁻⁶ mbarl/s). DELCO VALVE’s automated stations perform 100% testing with blockchain-based results logging. High-pressure gas tests simulate 25-year service cycles in 2 hours.

What Our Valuable Partners Say About Us

Rodrigo Peregrina Product Manager

"DELCO's API 6D-certified ball valves have operated flawlessly at 10,000 psi for 18 months in our sour gas fields. The extended maintenance intervals saved us 650 man-hours/year. We're finalizing a 3-year frame agreement for all our Gulf projects."

Oliver Dean Product Manager

"DELCO's Knife Gate valves lasted 3x longer than previous suppliers in our iron ore slurry lines. We're negotiating exclusive supply for all Pilbara operations.Our procurement team is prioritizing DELCO for Q4 reactor upgrades."

Emily Davis Product Manager

"The SIL-3 rated Flow control valves maintained ±0.5% flow accuracy during peak loads. We've reduced unplanned outages by 40% and will specify DELCO for all 2025 retrofit projects."
