2620 Series 2620-520-252 Dual Channel Rotary Union for Hydraulic Oil

A Dual Channel Rotary Union for Hydraulic Oil is a specialized device designed to transfer hydraulic fluid between stationary and rotating parts in machinery. It features two independent channels, allowing for the simultaneous transmission of hydraulic oil in both directions. This setup is crucial for applications requiring continuous rotation and reliable fluid transfer, such as in heavy machinery, industrial equipment, and automation systems. The dual-channel design ensures efficient operation, minimizes leakage, and supports high-pressure and high-temperature conditions, making it essential for maintaining the performance and longevity of hydraulic systems.
