No Protection from Overpressure
A vent valve only reacts to underpressure. In order to protect your pipelines, tanks and other containers against vacuum, we recommend the installation of a safety valve. When pressure gets too high, this gently discharges the excess and therefore prevents your pipelines, containers, silos, etc. from bursting.
Hard as Steel – Vent Valves Made from Stainless Steel
Our product range includes four different vent valves: Type VB01 and Type VB02 are optimised for utilisation with neutral, gaseous media such as air, gases and technical vapours and are made from high-quality, non-corrosive stainless steel 1.4404. It is sealed with a PTFE carbon seal. Concerning the male thread, the vents have the three nominal sizes ½", ¾" and 1". They are suitable for temperatures from a maximum low of -60°C to a maximum high of +225°C. Vent type VB01 is set at an opening pressure of -6mbar pressure difference. Type VB02, however, covers differential values between -100mbar and -800mbar. Types VB03 and VB04, on the other hand, are made from brass.
We are happy to support you with our expertise and experience in selecting the right vent valve for your pipeline system, tank or container. Just give us a ring or send an e-mail.
