RE 0478/08. ZSF; ZSFW Hydraulics osch Rexroth G /4 Function, section: Type ZSF The valve type ZSF is a pilot operated check valve in sandwich plate design. It is used for the leakage-free isolation of pressurized working circuits (e. g. pressing cylinders). Due to its favorable flow characteristics and the low cracking pressure of the main poppet (), it is particularly suitable for the pulling function and for filling e.g. the main cylinders at presses. The integrated pressure port (not for size 00) reduces the piping necessary for the high-pressure build-up. The valve basically comprises of a housing (), control spool (), main poppet (), and the compression springs (5) and (6). The valve allows for free flow from to. In the opposite direction, the main poppet () is held on the seat by the compression spring (5) and the pressure available at port. The pressure at the control port pushes the control spool () downwards, against the compression spring (6), and pushes the main poppet () off the seat. Now, the valve can also be flown through in the opposite direction. In order to dampen the opening velocity and to limit the dynamic load, a throttle check valve (7) is installed in size 00. The measuring point (8) allows for the recording of pressure developments. 5 6 Type ZSF F0 (size to 60) 5 6 In general: In channel of the upstream directional valve, you must imperatively provide a nozzle (separate order) (not for size 00). The nozzle Ø is to be designed according to the filling valve size (see below). In case of non-compliance, increased dynamic loads may occur having detrimental effects on the operating time. 8 7 Type ZSF (size 00) Nozzle fitting Size 40 50 6 80 00 5 60 00 ) Nozzle Ø in mm 0.8 0.8 0.8 0.8.0.0..5 4.0 ) Only for version "W"

Function, section: Type ZSFW The function of valve type ZSFW basically corresponds to that of type ZSF, however with built-on directional valve (separate order). Here, the control spool () is controlled via port and unloaded internally, via channel. The "Open" working direction of the control spool () is damped by a nozzle (4) integrated in the factory (see page ). 5 6 4 7 T Type ZSFW F0 (size to 60) (without pre-decompression and built-on directional valve, vertical working direction of the control spool) 5 6 7 8 4 In general: The nozzle (4) has been installed in channel of the directional valve port in the factory. In case of changes in the nozzle fitting, there may be increased dynamic loads which may have detrimental effects on the operating time.
