Non-return valve pilot operated

The non-return valve can be hydraulically unlocked through a separate connection. The screw-in cartridge meets the cavity standard according to ISO 7789. The valve is used for leakfree closing-off of a hydraulic line that must be unlocked under pressure as, for example, is the case for hydraulic cylinders in lifting or clamping devices. With this, volume flows of up to 80 l/min can be controlled at a maximum pressure of 350 bar.
