The Sun Hydraulics COBABDV (COBABDV) is a spring-biased closed, pilot-to-close check cartridge valve designed for hydraulic control systems. It features a 3:1 pilot ratio, allowing flow from port 1 to port 2 while blocking reverse flow. This valve is particularly useful in regeneration circuits, ensuring efficient operation by opposing pressure at the pilot port to pressure at port 1 with its nominal pilot ratio. Constructed with hardened steel seats, the COBABDV offers superior wear characteristics and contamination tolerance, enhancing longevity and reliability in various applications. The valve's design prevents reverse flow from port 2 to port 1 under any conditions, ensuring stable system performance. It also incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This feature helps maintain consistent operation and reduces potential maintenance issues. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 10 gpm (40 L/min), the COBABDV is capable of handling high-pressure applications efficiently. The valve also exhibits minimal leakage at high pressures, with a maximum valve leakage rate specified at roughly one drop per minute. Installation specifications include a hex size of 3/4 inch (19.1 mm) and an installation torque between 20 - 25 lbf ft (27 - 33 Nm), making it adaptable to standard system requirements without special tools or adjustments. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage that can be caused by exposure to petroleum-based fluids, greases, and lubricants. The model weighs approximately 0.20 lb (0.10 kg), allowing for easy handling and integration into existing hydraulic setups without significant alterations or weight concerns.

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.
