Hydroelectric Power

Designed for hydropower environments, Our rotary unions (joints) are engineered for continuous and reliable operation providing supply and return hydraulic power to blade actuators for adjusting pitch to adapt to flow conditions. Integrated with electrical slip rings and positioning sensors, rotary unions can provide precise and reliable position feedback in addition to fluid transfer.
