The main purpose of a vacuum valve is to prevent a hazardous creation of vacuums inside pressure vessels to avoid implosion. Our vacuum valve 414312 is delivered calibrated, tested and sealed and should be used for air or gases. When ordering depressurizing has to be defined and set between 0,05 and 0,40 bar. Vacuum valves in other materials for special working conditions, for example high temperatures or fluids, can be manufactured on request. Please ensure you let us know the required capacity, media, temperature, inlet dimension and type of system when placing your order for vacuum valves.
