Specifications · Operating Pressure:350BAR · Flow:320L/min · Pliot Ratio:1.8:1 · Internal Leakage:0.07ml/min.max.at operating pressure · Temperature:-30°C to +120°(-22°F to+250°F) · Cavity:T-17A · Fluids:Mineral-based fluids with viscosities of 7.4 to 420 cSt. Features · 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. Operation 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.
