SBH/YLH/YZBA/YZBSSBH, YLH, YZBA, YZBS Series Hydraulic Power Units
Hydraulic Power Units for Brakes and Rail Clamps HUAWU SBH/YLH/YZBA/YZBS
Huawu hydraulic power units for single-acting brakes and rail clamps. SBH supplies SB and SBD-C safety brakes (1–2 brakes per unit), YZBS supplies SBD-A, -B, -D brakes, YLH supplies YLZ wheel brakes (up to 8–12 per unit), and YZBA supplies YJA, YJD, YJE, YJJ rail clamps and YGZ rail brakes. Pressure 8–16 MPa, flow 8.6–32 L/min, motor 2.2–7.5 kW; dual-circuit versions (/2) control two mechanisms simultaneously or separately. Cone valves, an accumulator and a pressure relay maintain pressure; a hand pump provides emergency release without power.
