The Sun Hydraulics COBAXFV (COBAXFV) is a spring-biased closed, pilot-to-close check cartridge valve with a 3:1 pilot ratio. This valve allows fluid flow from port 1 to port 2 while blocking reverse flow, ensuring directional control and operation integrity in hydraulic systems. It is specifically designed for use in regeneration circuits where such control is crucial. The valve features hardened steel seats, enhancing its wear characteristics and contamination tolerance, thus ensuring long-term reliability and performance under challenging conditions. The COBAXFV operates with a nominal pilot ratio of 3:1, meaning that a pressure of 1000 psi at the pilot port will close the valve against a pressure of 3000 psi at port 1. This characteristic is vital for systems requiring precise control over pressure differentials. The design incorporates Sun's floating style construction to minimize internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum operating pressure of 5000 psi, a flow capacity of up to 10 gpm (40 L/min), and maximum valve leakage at 110 SUS (24 cSt) maintained at less than one drop per minute. The valve also features an installation torque range of 20 - 25 lbf ft and has an overall weight of approximately .20 lb (.10 kg). It utilizes Viton seals for the cartridge, making it suitable for systems using phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids. Overall, the Sun Hydraulics COBAXFV offers robust performance for hydraulic systems requiring reliable check functionalities, particularly in applications involving regeneration circuits where precise fluid control is necessary.

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.
