HAWE North America Inc. Pre-Fill Valve F 25-12

The check and pre-fill valves type F utilize a spring pre-loaded valve head. The check valves type F enable free flow in one direction and block the flow in the opposite direction. This valve is used as a high flow valve (check valve with hydraulic release) in top ram presses for quickly draining and replenishing press cylinders during opening and closing in rapid traverse mode. The smaller sizes may be equipped with a pre-relief device as an option to prevent pressure surges during decompression (high volume and high-pressure surge).
