Damcos BRC 052-A1 Hydraulic Double Acting Balanced Rotary Actuator The Damcos BRC 052-A1 is a high performance hydraulic double acting balanced rotary actuator specially designed for the demanding requirements of marine applications. This actuator is well known for its innovative helical spline design which enables steady, balanced high torque output during the whole 90° quarter turn operation. Whether it is for vital ballast systems or main valve controls, the BRC 052-A1 is a gold standard in maritime hydraulic engineering, providing unmatched reliability in tough, salt-laden atmospheres.   Hydraulic Actuator Specification: BRC 052-A1 Feature Specification Type Hydraulic Double-Acting Balanced Rotary Rotation 90° ± 1° (Quarter-turn) Max Working Pressure 210 bar (3046 lbf/in²) Burst Pressure 640 bar (9282 lbf/in²) Total Dry Weight 96 kg (approx. 212 lb) Oil Displacement 1500 cm³ (91.5 in³) Temperature Range -20°C to 80°C (-4°F to 176°F) Housing Material GGG40 Cast Iron Hydraulic Media Acid-free hydraulic oil (15-200 cSt)   Features Unique Helical Spline Technology: Provides balanced torque without needing big displacement for smooth valve operation. Marine-Grade Durability: Built to withstand sea air and saltwater corrosion, ensuring a long lifespan in deck or engine room settings. Zero Side Loading: The balanced rotational principle removes side forces and bending moments on the valve spindle, increasing valve seat life. Small Footprint: For maritime machinery locations where space is at a premium, but without sacrificing output power. Modular Flexibility: Works with all major types of quarter-turn valves and allows direct attachment of control blocks and position indicators.   Applications Marine Valve Remote Control (VRC) systems. Ballast water management and cargo handling systems. Emergency shutdown and fire-safety valve actuation. Onboard fluid transfer and process control.   NDMarineTech Engineer’s Guide: Filtration: These actuators are carefully manufactured. Keep your HPU (hydraulic power unit) to ISO 4406 18/16/13 cleanliness requirements at all times. Oil contamination is the main cause of internal seal bypass. Commissioning: Check the true concentricity of the valve stem during installation. Even with a properly balanced actuator, misalignment leads to early breakdown of the stem seal. Maintenance: If you hear a “chatter” while operating, check the crossover valve settings. The BRC 052-A1 is whisper silent, any vibration is an indication of air in the lines or impeded exhaust flow.
