  • The Ansan municipality dispatched the export market exploration delegation, composed of seven local SMEs, to Australia and New Zealand for eight days from December 9, and the delegation made outstanding achievements holding export consulting with local companies there (business worth $6,759,000) and signing export contracts worth $2,009,000.

    The seven companies including Asung Plastic Valve participated in the delegation. Australia has a big buying power. It is the world's 12th largest economy as of 2012 and its per capita income is $67,000, which is the 5th in the world. New Zealand has the world's 60th largest trading volume (as of 2013, source: WTO). Australia and New Zealand have depended on Chinese products which have very high price competitiveness, but the FTAs made them more attractive markets where Korean IT products and related technologies can find good opportunities for sales.

    Ansan will dispatch the export market exploration delegation to India next month, Russia in October and China in November. Park Bu-ok, the head of Business Support Department at the Ansan municipality said "We will follow up on the achievement of the delegation and support the promotion of business deals."

Therefore, Asung Plastic Valve will be able to provide distinct services to consumers, and secure strong competitiveness in the valve and water treatment industry at home and abroad."

    In addition, Asung Plastic Valve is currently developing a PP butterfly valve(600A), which can control greater volume of fluid than the existing butterfly valve(500A), for the first time in Korea and is planning to launch 600A valve before the end of this year.

    Kim Hyung-soo, Representative Director of Asung Plastic Valve, said "Asung Plastic Valve will secure global competitiveness beyond Korea, drawing on this newly developed product and technological excellence, and become a global plastic valve manufacturer. We will actively attend and promote our products at various exhibitions at home and abroad and, by doing so, we will achieve continuous growth in overseas sales."

    Since its foundation in 1967, Asung Plastic Valve has developed a variety of materials for plastic valves and pipes, U-PVC, C-PVC(HT-PVC), PP, PVDF, Clean PVC (clean flow) for semiconductor, C-PVC(FLAMBLOCK) for firefighting, etc. It exports products across the world, including Japan, China, Australia, Southeast Asia and Latin America.



  • The government of South Chungcheong province designated 37 local companies which have big growth potential as promising small and medium-sized enterprises (SMEs).

    For the next six years, these companies can get 1% additional cut in interest rate (3% in total) when they take the 'SME management stabilization loan.' They can also be preferentially provided support for creating sales routes in the domestic and overseas markets and technology and credit guarantee provided in joint with government agencies supporting SMEs. South Chungcheong province has designated a total of 442 local companies as promising SMEs since 1997. This year, the following companies were designated as promising SMEs.



  • Asung Plastic Valve (Representative Director Kim Hyung-soo) said it successfully developed 'Butterfly Valve 600A' for the first time in Korea.

With the development of Butterfly Valve 600A, Asung Plastic Valve further consolidated its leading position in the industry.

    Asung Plastic Valve was designated as one of businesses to receive R&D support from Korea Industrial Complex Corporation. This 600A valve can control more fluid than the existing Butterfly Valve 500A and is expected to provide an effective fluid control solution for waste water treatment and water treatment.

  • Asung Plastic Valve (Representative Director Kim Hyung-soo), a plastic valve and pipe materials manufacturer, has expanded business through continuous product development and has maintained the leading position in the industry.

    Since its foundation in 1967, Asung Plastic Valve has developed plastic valve and pipe made of a variety of materials with its own technologies. Currently, it produces valves, pipes and fittings made of PVC, PP, C-PVC for firefighting and industrial uses, PVDF, clean PVC for semiconductor, etc. and its outstanding product quality is recognized in overseas markets including Japan, China, Australia, Southeast Asia and Latin America.

The "Promising SMEs Certificate" granted by the government of Kyeonggi province is aimed at certifying outstanding small and medium-sized enterprises based in the province, which strive to improve corporate competitiveness and contribute to the development of the local economy. This year marks the 20th anniversary of the launch of the certificate.

    In addition, Asung Plastic Valve successfully developed 200A-sized butterfly valve lever type, exceeding the limit of 150A for the first time in Korea, and the new 200A product will soon be launched in the market. Butterfly valve LEVER TYPE 200A is drawing attention of the industry as it is expected to become an effective fluid control solution.

    As the Firefighting Management Act was reinforced recently, the application scope of sprinkler pipes made of C-PVC has expanded. In response, A-Sung Plastic Valve Clean Flow-Tech which is a subsidiary of Asung Plastic Valve, expanded production facilities in order to cope with increasing demand and seized the opportunity to increase its market share on the back of increased production volume and shortened delivery time.

    Asung Plastic Valve has actively participated in overseas water treatment and semiconductor exhibitions in order to introduce its excellent product quality and R&D results to consumers in the overseas markets.
