The check valve and pre-fill valve type F 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.
The valves type F25 - F80 are available with hydraulic release. Hydraulic release suppresses relief surges that can occur at high pressure and with a large consumer volume.
