Valve Springs

Ensuring the Valves Have a “Spring” in their Step

Valve springs have just one challenging function – to ensure the valves close in a controlled manner with enough force to ensure an air-tight sealing between the valve and the valve seat insert.


This entails the following requirements on the springs:

  1. CONSTANT CONTACT: When the valve is closed the spring force must be enough to prevent it from bouncing off the valve seat insert, while during opening it should arrest the valve tip from losing contact with the cam as it passes over the peak of the cam lobe ("fly-over").
  2. MINIMIZE SPRING FORCES: To achieve maximum fuel efficiency, frictional losses in the valve train should be minimized, for which spring force must be reduced by optimizing its shape and resistance to vibration.
  3. HEIGHT REDUCTION: By increasing fatigue limit and optimizing its design, spring height can be reduced. This improves fuel efficiency and gives more space and flexibility to design the engine compartment. Over an engine’s service life of about 200,000 km each valve spring will go through 300 million loading cycles.

Partnering with leading valve spring manufacturers in India has enabled Garima Global to develop and export high quality AutoGRACE® valve springs confirming to OEM specifications to discerning customers globally.


Garima Global supplies components for a wide variety of on-road, off-road, industrial and stationary applications such as: automotive (light duty) and light commercial, trucks (heavy duty), tractors (agricultural), earthmoving and construction machinery, generators, irrigation pumps, and defence / special purpose vehicles.

The brands for which we manufacture and export aftermarket products are Caterpillar, Chevrolet, Chrysler, Citroen, Cummins, Daewoo, DAF, Daihatsu, Detroit Diesel, Deutz, Fiat, Ford, Hino, Honda, Hyundai, International, Isuzu, Iveco, John Deere, Kamaz, Kia, Komatsu, Kubota, Land Rover, Leyland, Lister Petter, Lombardini, Mack, Mahindra, MAN, Massey Ferguson, Mazda, Mercedes Benz, Mitsubishi, Navistar, Nissan, Onan, Perkins, Peugeot, Renault, Scania, Suzuki, Tata, Tatra, Toyota, Ursus, UTB, Volvo, Yanmar and Zetor, amongst others.

Garima Global also export parts for air-brake compressors like Wabco, Bendix, Knorr, Cummins, Clayton Dewandre, Mercedes, Midland etc.


Garima Global has developed an extensive range of components for engine, braking, transmission, suspension, steering, chassis, electrical, lighting and other automotive sub-systems. To assist our customers with choosing the right product for their requirements we have published comprehensive catalogs with engine / vehicle models, interchange with references of OEMs and other popular aftermarket brands, fitment dimensions and other technical data. We strongly encourage you to contact us with your specific requirements so that we can email you the relevant catalogs, and we look forward to starting a mutually beneficial business relationship with you soon!

TYPES OF Valve Springs


Popular shapes of valve springs are:

cylindrical & symmetrical

cylindrical & asymmetrical



The cross section of the spring wire may be round or ovate / multi-arc. The ends of the springs may be ground flat and/or chamfered to ensure parallelism with the mating surfaces.


The older Cr-V steel grades are increasingly being replaced by Cr-Si for greater tensile strength and lower non-metallic inclusions. High-tensile Cr-Si-V and Cr-Si-Ni-V wires hardened by oil tempering or induction hardening and then annealed to reduce internal stresses are also used extensively. Surface may be shot blasted to induce residual compressive force that counteracts the tensile stress during operation.

Whether you requirements are for automotive, heavy-duty, OTR / earthmoving, industrial or agricultural engines, you can rest assured that Garima Global will supply a high quality valve spring made by one of the leading valve spring manufacturers in India under our watchful eye.
