4 General Information The CV 110 open valve is a parallel circuit valve which is designed to operate with a fixed pump in open center hydraulic systems up to pressures of 320 bar (4600 psi) and flow rates of up to 50 l/min (13 USgpm). The CV 110 on demand LS version is a valve which is designed to operate with a variable pump and in closed center systems up to a pressure of 320 bar (4600 psi) and flow rates of up to 50 l/min (13 USGpm). The CV 110 valve series offers the OEM the selection of a number of spools for optimal spool control at any load as well as a wide range of spool controls for different applications. Some of the CV 110 s main advantages are : Available from 1 to 6 sections as a monoblock valve Main relief valve Load check valves for each section Open & closed center option Direct acting relief valve for quick response time Power Beyond capability Exceptionally low spool leakage, less than 0.12 in³ (2 cm³) /min at 46 cst and 100 bar (1500 psi) and 40 c upon request Float, regenerative and specially tuned spools Full range of spool controls : joystick, pneumatic, hydraulic, electro-hydraulic proportional EHP and direct-acting solenoid (12VDC & 24VDC) BSP and SAE threads are standard and the following threads can be supplied upon request : Metric NPTF 4 Directional Control Valve
