In the field of industrial automation and fluid control, the requirements for valves are increasing day by day. Whether it is heating, ventilation and air conditioning (HVAC) systems, or flow regulation in water treatment and chemical processes, a control element with flexible operation, low energy consumption and high reliability is required.

Product Features and Advantages

The HK60-D-C Series Electric Butterfly Valve adopts advanced electric actuators, which not only supports standard on/off operation, but also can achieve precise control through a variety of adjustment signals such as 4-20mA or 0-10VDC. This flexible control method ensures that the valve remains stable and efficient between smooth switching, meeting different needs from simple switching to complex regulation occasions. The product adopts a quarter-turn full open or full closed design, and only 90° rotation is required to achieve command response, thereby greatly reducing the demand for operating torque, saving energy and extending the service life of the valve.

This series of valves adopts a wafer type installation structure, which is convenient for direct clamping between flanges, simplifying the installation process and system modification. For the valve body material, users can choose cast iron, ductile iron or even stainless steel (304 or 316) according to the working conditions; the sealing material has different options such as NBR, EPDM and VITON, ensuring the ideal use effect in a variety of media (such as air, water, oil, gas, etc.).

Technical parameters and intelligent performance

The HK60-D-C series 4-inch electric butterfly valve has a wide range of sizes and pressures. Conventional diameters are available from 2 inches to 24 inches, while the 4-inch version has the advantages of both standardization and customization. Its design focuses on low-torque operation, which greatly improves the efficiency of fluid passage and reduces energy waste caused by turbulence and pressure loss. Equipped with a high-precision feedback signal system, the valve can quickly and accurately adjust to the set position after receiving the control signal, and still maintain the “last position” in the case of power failure, ensuring the continuous and stable operation of the system.

In terms of intelligence, the HK60-D-C series not only supports standard electrical signal control, but also can achieve more detailed flow regulation by modulating signals. Combined with fieldbus (such as MODBUS, PROFIBUS, etc.) and remote monitoring technology, the valve can achieve intelligent diagnosis and real-time data feedback, providing strong support for system automation and industrial Internet.

This multi-field applicability not only reflects COVNA’s profound foundation in product research and development, but also provides industrial users with a variety of practical control solutions, promoting the continuous development of industrial automation and energy conservation and environmental protection.
