With the S1 model, we are looking at a self-actuated excess pressure valve. It is highly suited to working with steam, compressed air, gases and liquids.
It provides a fast and effective response to any change in demand, it boasts a design based on a single seated globe valve and has a shaft seal which is operated by a double layer stainless steel bellow.
To prevent damage to the bellow, it also has an anti-rotation system.
In addition, it also has a pressure chamber of membranes reinforced with intermediate fabric.
These characteristics provide a wide adjustment range of the set pressure – between 0.1 and 15 barg.
To finish, it is important to remember that the valve must be transported, handled and stored carefully. It should also be protected from adverse conditions such as dirt, humidity or frost.
