Disk Check Valve

The Disk Check Valve (butterfly check valve) is a compact and responsive check device, which is widely used in liquid, gas and steam transportation systems to prevent the backflow of the medium and ensure the stable operation of the pipeline system. This valve adopts a symmetrical butterfly design along the central axis. The valve disc opens under the action of the medium pressure. When the fluid flows back or the flow rate slows down to a certain extent, the valve disc quickly closes, effectively preventing backflow and water hammer phenomena, and protecting key equipment such as pumps and compressors.

Butterfly check valves have the significant advantages of small size and light weight, and are particularly suitable for occasions with limited installation space, such as high-rise buildings, ships, HVAC systems, etc. Its structure is compact and installation is flexible. It can be installed freely in horizontal or vertical pipelines without being restricted by spatial direction. Meanwhile, this valve has a short opening and closing stroke and a fast response speed, which can effectively reduce the system shock and improve the operational stability.

The internal components of the Disk Check Valve have been precisely designed with few moving parts, reducing mechanical wear and extending service life. It has excellent sealing performance. The sealing surface is often made of stainless steel or alloy materials, which has strong corrosion resistance and is suitable for the transportation scenarios of corrosive media such as acids, alkalis and salt water. In addition, this product has low pressure loss, remarkable energy-saving effect, and can reduce the operating cost of the system. It is particularly suitable for modern industrial systems with high requirements for energy efficiency.

In terms of installation and maintenance, the Disk Check Valve has a simple structure and is easy to disassemble and assemble. Most models support online maintenance, which is convenient for later inspection and maintenance. Its operation process does not require external energy drive and is completely dependent on the automatic control of medium flow, saving energy consumption and maintenance costs, and is suitable for continuous operation systems.

Disk Check Valve, with its superior backflow prevention performance, outstanding energy-saving characteristics and reliable sealing ability, plays an important role in multiple industries such as municipal water supply, HVAC, industrial circulating water, chemical engineering, petrochemical, etc., and is an indispensable key component in modern fluid systems.
