The Comatrol CP4481B0EB453 is a genuine pressure compensated flow control cartridge valve from the CP448 series. This direct-acting, spool-type, normally closed, restrictive-type valve maintains a constant flow rate from port 2 to port 1, independent of load pressure changes. It features a fixed 1.35mm (0.053 inch) orifice, Buna N seals, and is designed for a C10-2 cavity. The valve has a maximum operating pressure of 240 bar (3500 psi) and a maximum flow rate of 19 L/min (5 US gpm). Suitable for mineral-based or synthetic hydraulic fluids, it operates efficiently within a temperature range of -40 to 120°C (-40 to 250°F).
