1 Table H000/E ISO cartridge valves type LIM, LIRA, LIC Pressure controls: relief, reducing, compensator, ISO 7368 size from 6 to 80 Pmax 40 bar Pressure control valves in ISO cartridge design specific for relief, reducing or compensator functions They are made by a functional cover and a way SC LI slipin cartridge. Depending to the type of control, the cover is equipped with a pilot relief valve for the max pressure regulation and a solenoid valve for venting. The SC LI slipin cartridge is available with different poppet shape to optimize the pressure control, see section Functional cover Poppet Sleeve LIMHA3/E Spring Pressure relief pilot valve Solenoid pilot valve LIMM4 It is made by a poppet sliding into a sleeve and kept in normally closed position by the spring available with different cracking pressure values. Size: 6 to 80 (ISO 7368) Max flow up to 5000 l/min at Dp = 5 bar Max pressure: up to 40 bar MODEL CODE OF FUNCTIONAL COVERS for model code of slipin cartridge, see section LI MHA / 0 / V I X 4DC / F Cover according to ISO 7368 Function: MM = pressure relief control with manual setting; MHA = pressure relief control with solenoid valve for venting. Unloading when solenoid is deenergized; MHC = pressure relief control with solenoid valve for venting. Unloading when solenoid is energized; RA = pressure reducing control with manual setting. Open in resting position; C = pressure compensator to be coupled with flow control valves; CM = pressure compensator with mechanical max pressure regulation to be coupled with flow control valves.
