At KT, we specialize in producing high-quality die cast valve bodies for hydraulic, pneumatic, and automotive applications. With die casting machines ranging from 88 tons to 1600 tons, we are capable of manufacturing precision small valve bodies for pneumatic control systems as well as large transmission valve bodies for automotive systems. We use advanced technologies such as vacuum die casting and semi-solid die casting to ensure our valve bodies have low porosity, high density, and excellent airtightness, preventing gas or liquid leakage during operation.
We understand your concerns about corrosion resistance. In addition to offering corrosion-resistant aluminum alloys, we provide advanced surface treatments including electrophoresis, powder coating, and anodizing to meet your anti-corrosion requirements. Our goal is to provide one-stop die casting solutions that balance quality, efficiency, and cost-effectiveness.

✅ Core Advantages
- High Dimensional Accuracy & PrecisionOur valve bodies achieve CT4–CT5 level tolerances, meeting strict assembly requirements. CNC machining maintains tight tolerances of ±0.01 mm for critical features, ensuring seamless integration into fluid control systems.
- Excellent Airtightness & Low PorosityVacuum die casting technology minimizes porosity, ensuring the valve body is highly resistant to air or liquid leakage. Every part undergoes airtightness testing to eliminate safety risks associated with leaks.
- Smooth Surface & Versatile Finishing OptionsPrecision mold manufacturing and controlled process parameters ensure a smooth surface finish directly from the mold. Customers can choose from additional treatments such as polishing, sandblasting, plating, powder coating, or painting to meet specific aesthetic and corrosion resistance needs.
- Cost-Effective Mass ProductionDie casting is ideal for high-volume production, with unit costs decreasing as production scale increases. Our pre-production DFM analysis helps avoid costly mold changes, ensuring economical production even for large orders.
- Material & Process FlexibilityWe work with a variety of aluminum alloys including ADC12, A380, and 6061 to match different strength, weight, and corrosion resistance requirements. For complex or large valve bodies, we also offer gravity casting solutions.
- Comprehensive Quality ControlFrom raw material inspection to final testing, every stage is strictly controlled. We use advanced testing methods including CMM dimensional measurement, leak testing, and material analysis to ensure each valve body meets project requirements.
