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 on presses.
