The range of products manufactured by Hunger Maschinen GmbH also include special valves for hydraulic cylinders in plate or insert design to safeguard and control pressure and for lowering brake control. The prefill valves in nominal sizes from 100 to 400 mm in diameter are particularly well received by our customers
Due to their good flow construction prefill valves serve for feeding and filling the main cylinders on presses. Because their function is similar to that of check valves they can be used for blocking up pressure loaded press cylinders without any leakage. The Hunger prefill valve is available in two structure shapes – as container assembly and as case valve with flange port.
