Customisation
Tailored valve design for optimal performance and compliance
Overview
Every engine has unique demands, and a one-size-fits-all solution is not always enough. We specialise in the customisation of EGR, intake throttle, and exhaust throttle valves, ensuring our components are perfectly matched to your application.
Whether on-road, off-road, or marine, our customised solutions help achieve the right balance of performance, durability, and emissions compliance.
By combining advanced design tools, 3D modelling, and extensive validation processes, we develop valves that meet your precise requirements.
From flow characteristics and actuation methods to packaging constraints and material choices, our engineering team works collaboratively with customers to deliver optimised solutions that integrate seamlessly into their systems.
With a focus on flexibility, innovation, and quality, our customised valve solutions enable engines to perform reliably under even the most demanding conditions.
By tailoring each product to your specifications, we provide not only components but complete air management solutions that support efficiency, compliance, and long-term value.

Production Capabilities
Inhouse production of GT’s own design pneumatic actuators. Flexible and robust line for varying recipes depending on design requirements.
- 35mm cylinder
- 50mm cylinder
- 65mm cylinder (in production)
100% of actuators are tested for stroke length, pressure intensity with safety factor and functional spring return before getting engraved as a mark of approval and for date/serial no. traceability.
CNC machining for low-mid volume serial production and rapid inhouse prototyping.
All milling machines are 4-axis/twin pallet equipped with high pressure through spindle coolant and tool length wear detection.
Machines include;
- Doosan HP5100
- Heller H5000 & H6000
- DMG Mori NHX5500
Welding of the lever assemblies is one of the core sub-processes in the majority of GT products.
The purpose-built weld cells are used for serial production and rapid inhousee prototyping.
We have inhouse weld-sectioning and macro-analysis of the weld batches for the finest quality.
Drilling of the lever assemblies is another of the core sub-processes for the majority of GT products.
This is a simple but highly precise process which is critical for the durability and longevity of the valve performance throughout the life of the products.
- Robodrill – high performance vertical mill
Featuring; early fault detection, high pressure through spindle coolant, ultra fast tool change, high tool capacity and pneumatic clamping.
Universal Assembly Line
Bushing Operation
Precision control for bushing process ensuring quality bushes parts for 100% of valves. Bush position and press force traceability and control.

End of Line Test Station
100% of sample and serial production valves go through an EoL function and leakage test.
Test functions include;
- Electric actuator calibration
- Open/Close function testing
- Valve external leakage
- Valve internal + external leakage
- Serial number traceability
- Smart camera detection and measurement
- Data traceability and serial no. identification
- Adhesive label / engraved plate etc
CoBot Quality Firewall
High resolution SMART camera, mounted to a robotic arm allows any customer/design specific additionss to the product to be coveredd from a quality perspective that can’t be catered for in the previous processes.
Keeping high quality assurance with maximum line flexibility.
