4 General Information The CV430 open center valve is a parallel circuit valve which is designed to operate in open center hydraulic systems up to pressures of 320 bar (4600 psi) and flow rates of up to 80 l/min (21 USG pm) The CV430 on demand LS version is valve which is designed to operate with a variable pump and in closed center system up to a pressure of 320 bar (4600 psi) and flow rates up to 80 (21 USGpm). The CV430 valve offers a wide selection spools for optimal spool control of any load, as well as a wide range of spool controls for different applications. Some of the CV 430 s main advantages are : Exceptionally Low Spool leakage rates of less than 2 cc/min (or inch 3 /min) Load Check valves on each spool. Direct Acting Main Relief Valve for quick reponse. Float Function for the lowering circuit. Regen Function for the tilt circuit. DIRECT MOUNTED JOYSTICK for both float and regen. Cable Control option. Power Beyond option. BSP and SAE Threads are standard, but also Metric and NPTF can be offered upon request. Directional Control Valve 3
