Counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio.

Technical Features

  • Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.
  • Turn adjustment clockwise to decrease setting and release load.
  • Full clockwise setting is less than 200 psi (14 bar). Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.
  • Reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages.
  • Sun counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in the circuit.
  • Two check valve cracking pressures are available.
  • Use the 25 psi (1,7 bar) check unless actuator cavitation is a concern.
  • This valve does not have positive seals on the pilot section and will pass between 2 and 20 in3/min./1000 psi (0,03 and 0,3 L/min./70 bar) between port 2 and port 3, depending on load pressure. This is a consideration in master-slave circuits and in the leak testing of valve-cylinder assemblies.
  • All 3-port counterbalance, load control, and pilot-to-open check cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size).
  • Stainless steel cartridge options P or W are intended for use within corrosive environments with all external components manufactured in stainless steel or titanium. Internal working components remain the same as the standard valves.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
