By using Inconel 718, which has high fatigue strength, as the bellows material, it has excellent corrosion resistance, heat resistance, and spring load characteristics.

By adopting a "damper spring" that suppresses the resonance of the bellows as standard between the bellows and the baffle, stable sealing performance and excellent durability are achieved.

As a Quenching seal, an auxiliary seal "ABC ring" with a split floating ring is adopted as standard, and the Quenching fluid is flowed near the sliding surface by the baffle provided inside the bellows to effectively perform cooling, heat retention and cleaning. ..

A wide range of applicable temperatures is achieved by using Grafoil, which has excellent heat resistance and chemical resistance, instead of synthetic rubber O-rings and PTFE packing. Since the Sliding material has a graphoil mount structure, the Sliding material can be replaced and maintains good sliding surface accuracy even at high temperatures and extremely low temperatures.

The Sliding material uses Silicon Carbide and Hard non-impregnation carbon to obtain excellent wear resistance and blister resistance.

Since it is possible to operate without a flushing cooler even at high temperature specifications, it is possible to reduce equipment costs and maintenance labor.
