Controlling (super) high steam temperatures and pressure levels are essential in these processes. The proper functioning of our piston rings is crucial in this. Once installed, they should perform 100% immediately without any ‘break-in’ time. Injection coolers and different types of safety- and control valves all use our piston rings.

We supply custom-made piston rings, starter air valve rings and special seals for various steam (train) organisations and foundations. This allows them to operate their newly restored materials, in their full former glory. This often involves custom-made products, as standard dimensions are generally not included. Specially alloyed cast irons and self-lubricating bronze types are often used here.
