Prefill Клапан, sandwich Плита design ZSF

Description Size 32 … 200 Component series 1X, 2X Maximum operating pressure 350 bar Maximum flow 7000 l/min Features Pilot operated check valve in sandwich plate design Directional valve set-up, optional High-pressure connection (NG32 … 160) Integrated throttle check valve (NG50, 63, 80 and 200) Product description Notice: With size 32, 40, 100, 125, 160 a nozzle (separate order) must imperatively be provided in channel P of the upstream directional valve. The nozzle diameter is to be designed according to the prefill valve size (see "Schematics"). In case of non-compliance, increased dynamic loads may occur having detrimental effects on the operating time.
