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 pilot port opposes pressure at port 1 at a ratio of 1.8:1. This valve is most often used in regeneration circuits.
Sun Hydraulics® Check Valve, 5000 psi, 160 gpm Flow Rate, Number of Ports/Ways: 3, Buna-N Seal, Additional Information: 1-5/8 in Hex Size, 350 to 375 lbf Torque Rating, 4 psi Cracking Pressure
- 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
