The valve specialist Goetze’s Series 4000 safety valve is now available with the ASME certification. The extended certification makes the valve even more versatile in applications where particularly high requirements must be met with regard to the cleanability of surfaces in contact with the medium.
Particularly for applications in the medical or pharmaceutical sector, the requirements for the manufacture and cleanability of the valves are very high. As with the safety valve 4000, contamination can be avoided by not allowing nests and dead spaces. For this purpose, the area of the spring chamber is separated from the media chamber by an elastomer diaphragm. The media chamber itself can be opened with the aid of the clamp connections. This ensures simple and professional cleaning.
The valve is secured against unauthorised adjustment by a visible sealing disc pressed into the cap. This means that the usual sealing wire, which is not easy to clean, can be dispensed with. This allows simple assembly or disassembly with standard tools without any changes or effects on the set pressure of the valve. The set pressure can vary between 0.4 and 16 bar.
