The Sun Hydraulics COJCXCV (COJCXCV) is a high-performance pilot-to-close check cartridge valve designed for advanced hydraulic systems. It features a nominal pilot ratio of 1.8:1, allowing it to effectively manage flow from port 1 to port 2 while blocking reverse flow under any condition. The valve is engineered to close against pressures up to 1800 psi (125 bar) at port 1 when the pilot pressure is set at 1000 psi (70 bar). This capability ensures reliable operation even in systems where pilot pressure may momentarily decay or be lost. Constructed with Sun\u2019s floating style design, the COJCXCV minimizes potential internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This design detail enhances the valve's operational reliability and longevity. The valve fits into a T19A cavity and belongs to the Series 4 lineup, supporting a maximum flow capacity of up to 160 gpm (610 L/min) and can withstand operating pressures up to 5000 psi (350 bar). Additionally, this model has an impressively low maximum leakage rate of only one drop per minute at fluid viscosity of 110 SUS (24 cSt), ensuring efficient performance with minimal fluid loss. It requires an installation torque between 350 - 375 lbf.ft (474 - 508 Nm) and has a compact model weight of approximately 2.60 lbs (1.20 kg). The COJCXCV uses Viton seals, indicated by the seal kit part number: Viton: 990019006, further emphasizing its suitability for demanding hydraulic applications where robustness and precision are critical.

This valve is a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio. The valve allows flow from port 1 to port 2 and blocks reverse flow. Pressure at the external pilot port opposes pressure at port 1 at a ratio of 1.8:1. Port 3 is blocked.
- Nominal pilot ratio is 1.8:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 1800 psi (125 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.
- 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.
- With equal pressures at all ports the valve is closed.
- 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.
