The Sun Hydraulics CDAPBCN (CDAPBCN) is a specialized hydraulic check valve designed for precise control and synchronization in hydraulic systems, particularly in dual cylinder steering applications and other scenarios requiring exact phase adjustments between cylinders. This valve is integrated directly into the piston of a cylinder, activating mechanically at the end of the stroke to allow flow through the piston, thereby synchronizing two cylinders by equalizing their positions at both ends of their travel. The CDAPBCN features a unique back-to-back phaser check configuration with a mechanically actuated poppet at port 1. It is crucial that this valve is installed with axial actuation direction only and that the contact surface remains perpendicular to the valve axis within 5 degrees to ensure proper function and avoid undue side forces which it is not designed to handle. Additionally, it should not be cam operated nor used as a mechanical stop. The design includes an internal maximum stroke limit for the poppet of 1.2 mm (.047 in), which must be adhered to using an external mechanical stop. Engineered for low leakage, this valve offers a maximum leakage rate of less than one drop per minute (0.07 cc/min), ensuring efficient operation even under demanding conditions. The CDAPBCN also helps in reducing unnecessary force on rod glands at the end of cylinder strokes and can assist in bleeding air in vertically mounted cylinders at stroke end, enhancing overall system reliability and performance. This model utilizes Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining, ensuring consistent operation and longevity. The specific cavity required for this valve is T162A (with port 2 unused), and it has a flow capacity of 1.25 gpm (4.7 L/min). Installation requires precision with torque specifications set between 20 - 25 lbf.ft (27 - 33 Nm) and uses Viton seals for enhanced durability under various operating conditions.

The phaser check is a pair of checks, back-to-back, with the poppet at port 1 mechanically actuated. The valve is meant to be installed into the piston of a cylinder. When the cylinder reaches the end of its stroke the poppet in the phaser check is shoved off its seat allowing flow through the piston. This allows two cylinders to get back into phase.

  • This valve is not designed to handle side forces. Actuating direction must be axial, and contact surface must be perpendicular to valve axis to within 5°.
  • This valve is NOT meant to be cam operated.
  • This valve is NOT to be used in place of a mechanical stop.
  • Maximum stroke of the poppet must be limited to .047 in. (1,2 mm) by a mechanical stop other than the valve itself.
  • Note: Port 2 of the T-162A cavity is not used with this valve.
  • Check valves offer extremely low leakage rates with a maximum leakage of less than 1 drop per minute (0,07 cc/min).
  • A cylinder that does its work while extending can put a large load on the rod gland at the end of its stroke. A phaser check in the piston can limit the unnecessary force on the gland.
  • If you need to monitor the pressure in a cylinder, a phaser check can prevent the trapping of a false pressure value by a load holding valve.
  • A phaser check in the piston of a vertically mounted cylinder will bleed air at the end of the stroke.
  • Phaser checks in the pistons of master/slave cylinders will synchronize the cylinders simply by taking the mechanism to the end of its travel in both directions. This lends itself to dual cylinder steering applications.
  • 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.
