The Sun Hydraulics COBABFV (COBABFV) is a sophisticated check cartridge valve designed for high-performance hydraulic systems. This valve features a spring-biased closed, pilot-to-close configuration with a 3:1 pilot ratio, facilitating reliable operation by allowing flow from port 1 to port 2 while blocking reverse flow entirely. It is particularly effective in regeneration circuits, enhancing system efficiency and control. Constructed with hardened steel seats, the COBABFV valve offers exceptional wear resistance and contamination tolerance, ensuring long-term durability and consistent performance even under challenging conditions. The valve's design incorporates Sun\u2019s floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This model is capable of handling a maximum operating pressure up to 5000 psi (350 bar) and a flow capacity of up to 10 gpm (40 L/min). The nominal pilot ratio of 3:1 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. Furthermore, the COBABFV features an installation torque range from 20 to 25 lbf ft (27 to 33 Nm) and weighs approximately .20 lb (0.10 kg). For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available; however, these should not be exposed to petroleum-based fluids as it could damage the seals. The precise engineering and robust construction of the Sun Hydraulics COBABFV make it an essential component for advanced hydraulic applications demanding high reliability and precise fluid control.

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.
