The Sun Hydraulics COBABCV (COBABCV) is a robust pilot-to-close check cartridge valve designed for high-performance hydraulic systems. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow from port 2 to port 1, ensuring operational security and system integrity. The valve operates with a nominal pilot ratio of 3:1, meaning that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 3000 psi at port 1. This feature is crucial in applications involving regeneration circuits where such pressure dynamics are common. The COBABCV model is engineered with hardened steel seats, enhancing its durability and resistance to wear even in the presence of contaminants. It also incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This model has a maximum operating pressure capability of 5000 psi and supports fluid flows up to 10 gpm (40 L/min). Key specifications include a maximum valve leakage at 110 SUS (24 cSt) of approximately one drop per minute, indicating high sealing efficiency under operational conditions. The valve's hex size is 3/4 inch, and it requires an installation torque between 20 -25 lbf ft. Weighing just about .20 lb, this model is compact yet sturdy enough for demanding applications. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, exposure to petroleum-based fluids should be avoided as it could damage the seals. Overall, the Sun Hydraulics COBABCV offers reliable performance in hydraulic systems requiring precise control over flow and pressure reversal, making it an essential component for efficient industrial operations.

This valve is a spring biased closed, pilot-to-close check cartridge that has a 3:1 pilot ratio. The valve allows flow from port 1 to port 2 and blocks reverse flow. Pressure at the pilot port opposes pressure at port 1 at a ratio of 3:1. This valve is most often used in regeneration circuits.
- Features hardened steel seats for excellent wear characteristics and contamination tolerance.
- Product is not available with A and B spring ranges (4 and 15 psi (0,3 and 1 bar)).
- Pressure at the port 2 area directly opposes pilot pressure.
- Reverse flow through the valve from port 2 to port 1 is not possible under any condition.
- Nominal pilot ratio is 3:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 3000 psi (205 bar) at port 1. Any decay or loss of pilot pressure could allow the valve to open, even if it is a momentary decay or loss.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
