Starting with Joil Valve Engineering in 1986, we began developing professional technologies for the district heating and cooling industry. For the past 40 years, we have been supplying specialized welded metal-seated butterfly valves for district heating and cooling to Korea and the global market. Based on our extensive expertise, we have established and operated an incomparable production system. We have enhanced our systems to be more rational and focused on technological development, laying the foundation for future growth. Furthermore, we have restructured our organization to respond swiftly to global environmental changes and are dedicated to environmental protection.
We will do our best to comply with international standards and become one of the most respected companies in the world. We look forward to your support and assistance, and we ask for your continued trust and encouragement in our efforts and transformation.
Thank you.
