The Sun Hydraulics COBABEN (COBABEN) is a meticulously engineered spring-biased closed, pilot-to-close check cartridge valve, featuring a 3:1 pilot ratio. This design facilitates flow from port 1 to port 2 while securely blocking any reverse flow. The valve's operation is characterized by the pressure at the pilot port counteracting the pressure at port 1 with a 3:1 ratio, making it particularly effective in regeneration circuits where such control is crucial. Constructed with hardened steel seats, the COBABEN valve offers exceptional wear characteristics and high tolerance to contamination, extending its operational lifespan under challenging conditions. It boasts a maximum operating pressure of 5000 psi (350 bar) and a flow capacity up to 10 gpm (40 L/min), ensuring robust performance in various hydraulic applications. The valve's nominal pilot ratio indicates that a pressure of 1000 psi (70 bar) at the pilot port can close the valve against a pressure of 3000 psi (205 bar) at port 1. Designed for precision and reliability, the COBABEN 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 feature enhances the overall functional stability and reliability of the valve system. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Installation specifics include a valve hex size of 3/4 in. (19.1 mm) and an installation torque between 20 - 25 lbf ft (27 - 33 Nm), ensuring easy integration into existing systems without requiring extensive modifications. Additionally, this model has an extremely low weight of .20 lb (0.10 kg), contributing to its ease of handling and installation in various configurations.

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.
