DSTI 4-passage HVH Series rotary unions are available with either #8 or #16 SAE-ORB connections and feature independent high-flow channels suitable for vacuum and bidirectional pressures up to 5,000 PSI [345 BAR]. Designed for heavy equipment and outdoor-use applications, the heavy-duty construction consists of an alloy steel shaft, ductile iron housing and black oxide coating for improved corrosion protection.
This series is ideal for equipment that is operated in harsh, outdoor environments such as forestry, mining and construction industries.
Need to combine fluid with electrical power, signal and/or data transfer? No problem. All HVH models come with a .50" [12.7 mm] open through bore for integrating one of our standard electrical slip rings with it.
