Doosan Infracore Receives Jang Young-sil Award for Excavator Hydraulic Control Core Component

Doosan Infracore's main control valve 'DCV300' for medium-sized excavators has been recognized for its excellent technological development achievements and received the IR52 Jang Young-sil Award.

[Asia Economy Reporter Ki-min Lee] Doosan Infracore announced on the 23rd that its main control valve (Main Control Valve) DCV300, a core hydraulic control component for excavators, has won the ‘IR52 Jang Young-sil Award’ hosted by the Ministry of Science and ICT.

The main control valve is a key component that delivers hydraulic pressure to each operating part of the excavator to control the movement and operation of the equipment. Because it requires precise technology to distribute and control all power of the excavator while preventing power loss, it demands the highest level of technical skill among the parts used in excavators.

Doosan Infracore began developing the DCV300 in 2014 and, together with domestic hydraulic-related partners, went through design, material development, verification, and manufacturing processes, successfully commercializing it in earnest after five years.

Among MCV products for medium-sized excavators, the DCV300 model is the world’s first to be developed and commercialized with a ‘Mono Block Housing’ (integrated frame).

Through the development of the integrated MCV, Doosan Infracore improved fuel efficiency by 12% compared to the existing combined MCV and reduced manufacturing costs by more than 20%. It is designed to be highly scalable, with high durability and applicability to next-generation hydraulic systems that integrate electrical and electronic technologies.

A Doosan Infracore official said, "The DCV300 was recognized for its global technological competitiveness by being selected as one of the ‘Top 10 Technologies of the Year’ by the Korea Federation of Mechanical Engineering Societies last year and now winning the Jang Young-sil Award. We will continue to apply the technological know-how accumulated through the development of the DCV300 to the development of next-generation electro-hydraulic systems and achieve innovative technological development results."

The IR52 Jang Young-sil Award is an industrial technology award that has been recognizing excellent corporate technological research achievements since 1991, awarding one product each week for 52 weeks a year. Doosan Infracore’s DCV300 was selected as an excellent technology in the 46th week of this year, and Doosan Infracore previously won the Jang Young-sil Award in 2012 and 2013 for the ‘Wear-resistant Excavator Front Joint’ and the ‘Eco-friendly Small Diesel Engine (G2 Engine),’ respectively.
