When designing a powered system, we first gather information on the 
number of functions as well as flow and pressure requirements for 
each.  Every powered system is different. Harken is committed to 
providing systems designed specifically to account for flow, pressure, 
and other performance requirements of each project. We also talk to 
the customer about how the boat will be used to assure the system 
will perform as expected.
Harken DC hydraulic systems power functions including cylinders, 
vangs, lifting keels, winches, furlers, windlasses, and small bow 
thrusters. The system is comprised of three main components:
• The power unit includes motors and pumps to deliver oil. We offer a variety of 
options for different flow and pressure needs. All power units include return 
filtration, motor temperature sensors, and tank level sensors.
• Valves direct and deliver oil to hydraulic functions. Our family of modular 
cartridge manifold valves stack together for an extremely flexible system. These 
zero-leak valves have flow and pressure controls as well as pressure relief. 
• The electrical control box is the brain of the system. On-deck push button controls 
turn valves and pumps on/off. Our latest control boxes all include a small PLC 
controller to map inputs to outputs. Boxes come pre-wired. Simply plug M12 
cables to connectors on the outside of the box.
We provide hands-on service for all Harken hydraulic power 
systems and we look forward to serving our customers 
beyond their expectations. Please contact us 
with any of your hydraulic powered system 
needs. We will be happy to provide detailed 
specifications and a quote.
