The Hawe F series check valve is a non-return pre-fill valve that is designed for intensely high flow rates. Check valves block the oil flow in one direction and open in the other direction. Pre-fill valves are check valves with a hydraulic release.
This valve is a spring-loaded disk valve and has zero leakage in the closed state. The valve is attached directly to the cylinder and clamped between the base of the cylinder and the welding-neck flange. Alternatively the valve is installed in the line between the front faces of the welding-neck flanges. Hydraulic release is available to suppress relief surges that can occur at high pressure and with a large consumer volume.
Key technical specifications of the Hawe F series valve include:
- Maximum pressure: 400 bar
- Flow rate: 100-7000 litres/ minute
Common applications include press control systems and injection moulding machines.
