The Sun Hydraulics COHCXDV (COHCXDV) is a sophisticated hydraulic valve designed for precise control in fluid power applications. This spring-biased closed, pilot-to-close check cartridge operates with a nominal pilot ratio of 1.8:1, enabling reliable operation under varying pressure conditions. Specifically, it requires a pilot pressure of 1000 psi to close against a pressure of 1800 psi at port 1, ensuring that any loss or decay in pilot pressure could momentarily open the valve. Constructed to allow flow from port 1 to port 2 while blocking reverse flow entirely, the COHCXDV ensures operational security and efficiency. The valve's design includes an external pilot port where pressure opposes the main port pressure at a controlled ratio, contributing to its stability and responsiveness. Notably, this model incorporates Sun's floating style construction which minimizes potential internal binding caused by excessive installation torque or variations in cavity/cartridge machining. This model is housed within a T17A cavity and belongs to Series 3, supporting up to 80 gpm/320 L/min flow capacity with maximum operating pressures reaching up to 5000 psi/350 bar. The valve demonstrates exceptionally low leakage rates at approximately one drop per minute under standard conditions (110 SUS/24 cSt), which underscores its efficiency and precision in fluid control. Additional technical specifications include a hex size of 1-1/4 inches for installation, with recommended torque settings between 150-160 lbf ft for optimal performance without risking damage through over-tightening. Weighing at approximately 1.80 lbs, the COHCXDV is robust yet manageable for installation and maintenance activities. For those requiring specific sealing solutions, it supports Viton seals through kit number 990017006. This configuration makes the COHCXDV an ideal choice for applications demanding rigorous control and reliability in hydraulic systems.

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.
