HVAC Systems (Heating, Ventilation, and Air Conditioning) provide heating, ventilation, and air conditioning in large-scale industrial environments, and are primarily used in factories, manufacturing plants, warehouses, and large commercial buildings. These systems play a crucial role in maintaining process efficiency, product quality, and the comfort and safety of workers.

Cooling towers and chillers are essential components of HVAC systems, and Jeongdo Machinery manufactures butterfly valves and actuators that are well-suited for such air conditioning systems. These products deliver excellent performance in reducing pumping costs and improving power efficiency through precise control capabilities, ultimately lowering operational expenses.

Jeongdo’s butterfly valves feature a cushioned ring seat design that offers excellent sealing and durability, significantly extending product life and ensuring stable operation of HVAC systems. In chilled water lines, the potential for scale formation is high due to the ingress of foreign matter and microorganisms. This risk is especially elevated when systems are unused for long periods, leading to scale buildup on the valve’s seat and disc surfaces, which can impair valve functionality.
To address this, Jeongdo offers specially coated disc surfaces that prevent scale formation and contamination, playing a vital role in maintaining the reliability and efficiency of HVAC systems.

Additionally, Jeongdo’s butterfly valves are known for their high control accuracy, enabling precise flow regulation, which reduces pump load and optimizes power usage. With outstanding durability and sealing performance, they operate reliably under high-temperature and high-pressure conditions, and effectively mitigate scale formation in chilled water pipelines, thereby reducing maintenance costs.
Thanks to these technical advantages, Jeongdo Machinery’s butterfly valves help reduce energy consumption, maximize operational efficiency, and have become a trusted choice in a wide range of industrial applications, including semiconductor and ultrapure water systems.
