The Sun Hydraulics COBAXCV (COBAXCV) is a robust, pilot-to-close check cartridge valve designed for high-pressure hydraulic systems. This valve facilitates flow from port 1 to port 2 while preventing reverse flow from port 2 to port 1 under any conditions, ensuring reliable operation and system integrity. The COBAXCV features a nominal pilot ratio of 3:1, meaning it requires a pilot pressure of approximately 1000 psi to close against a pressure of 3000 psi at port 1. This capability makes it particularly suitable for regeneration circuits where such control precision is crucial. Constructed with hardened steel seats, the COBAXCV offers excellent wear characteristics and high contamination tolerance, extending the valve's service life even under harsh conditions. It incorporates Sun's floating style construction which minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. Additionally, the valve is designed to operate up to a maximum pressure of 5000 psi and has a flow capacity of up to 10 gpm. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as they can damage the seals. The model also specifies that it does not support certain spring ranges (A and B), specifically excluding ranges of 4 and 15 psi. Installation specifications include a hex size of 3/4 inches for the valve and an installation torque between 20 -25 lbf ft, ensuring straightforward integration into existing hydraulic systems without special tooling requirements.

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.
