Frequently Asked Questions

The Exhaust Gas Recirculation (EGR) valve recirculates a controlled portion of exhaust gases back into the intake system. This lowers combustion temperatures, which helps reduce nitrogen oxide (NOx) emissions and supports compliance with emissions regulations.

Hot-side EGR valves redirect exhaust gases before the turbocharger, operating at higher temperatures, while cold-side valves direct gases after cooling. Hot-side systems provide quick response, while cold-side systems offer more stable, cooler flow for durability and control.

Intake throttle valves regulate the amount of air entering the combustion chamber, enabling precise EGR operation, optimising combustion stability, and supporting emissions control strategies.

Exhaust throttle valves manage backpressure in the exhaust system. This improves EGR effectiveness, supports Diesel Particulate Filter (DPF) regeneration, and enhances overall aftertreatment system efficiency.

Yes, our valves are engineered to perform in a wide range of environments, from highway trucks to construction, agricultural, and marine engines, with durability and reliability at the forefront of design.

Absolutely. We specialise in customising EGR, intake throttle, and exhaust throttle valves to meet unique specifications, including flow rates, materials, actuation types, and packaging constraints.

We use advanced alloys, composites, and coatings designed to withstand high thermal and mechanical stresses, resist fouling, and extend service life in demanding operating conditions.

Electronically actuated valves provide faster response and more precise control of airflow, allowing better integration with engine control systems. Pneumatic valves are cost-effective and robust but offer less precision.

Our valve systems are designed and validated to meet international standards, including Euro VI, Tier 4, and beyond. They enable engines to achieve lower NOx and particulate emissions while maintaining performance.

All valves are rigorously tested for thermal fatigue, vibration resistance, pressure cycling, durability, and long-term performance to ensure they meet the most demanding safety and quality standards.

Yes, our electronically actuated valves are fully compatible with modern engine control units (ECUs) and can be integrated with digital diagnostics and predictive maintenance systems.

We supply to a wide range of industries, including automotive, commercial vehicle, off-highway (construction and agriculture), and marine, delivering tailored solutions for each sector’s unique challenges.
