Piston installation - Import export

When to use piston rings? When piston rings with excellent wear properties are required When simple assembly is of great importance When high edge loads occur When tailor-made solutions based on iglidur® materials are required When not to use piston rings? When the piston rings should seal simultaneously When different diameters should be covered by one part Before: with piston rings: Why complicate things when it can be done differently? Replace elaborately stamped PTFE tapes with a single clip-on guide ring, such as in lifting elements, control valves and fittings. We offer iglidur® piston rings made of freely selectable materials for a wide range of applications. Special properties Easy to assemble Low-priced More wear-resistant than PTFE-bonds Higher load capacity Defined dimensions different materials per ex. iglidur® J, J350… iglidur® piston rings - application examples When to use piston rings?

Individual filled gas springs are excluded from replacement. Gas springs are maintenance-free, self-contained systems that are filled with nitrogen under high pressure. For end-of-travel damping and lubrication, a defined amount of oil is also contained inside. The gas springs contain a nonreturn valve in a threaded pin on the pressurised pipe, which allows the pushing force to be lowered at a later time. Gas pressure springs in the sizes 04/12 and 06/15 must be stored and installed with the piston rod extending downwards. As of size 08/19, storage and installation in any orientation is possible. Keep in mind, however, that end-of-travel damping is effective only when the piston rod extends downwards. As a consequence of the physical properties when filling a gas spring, a tolerance range of ±5 % results for the rated pushing force. Gas springs are filled with nitrogen under high pressure and under no circumstances should they be opened or overloaded.

Our mechanical pressure switches are entirely “Made in Germany”. Hydrostar’s extensive and long product experience along with continuous improvements in hydraulic pressure measurements enables the production of high-quality, accurate and reliable mechanical pressure switches. These properties have proven themselves consistently worldwide. The core of the pressure switch line is the special extreme long-lasting sealing combined with the piston-springprinciple and its exceptionally accurate and reliable change-over switch. The minimum switching path with an additional throttle bore allows for a lengthy and durable life cycle. Another special feature is the potential adjustability of the pressure switch on client-side, even after the installation. Mechanical piston pressure switch for pressure monitoring Pressure range 5 to 350 bar Special Features Precise and Reliable Compact Design Change-over switch High overpressure security
