Oil seal rings - Import export

Spherical valves are installed upstream of the turbine as shutoff devices specifically for high pressures at the end of the penstock. Their main function is to close off the penstock during normal shutdown or load shedding of the turbine. The seal is a metal sliding ring which is generally moved by water hydraulics. The MANOY® system seal WP, type 434 (outer sealing) and the inner sealing type 439, were developed for sealing of the sliding ring. The profile dimensions can be customized for maintenance or specific requirements.

The X‑ring is a continuous, seamless vulcanized ring with a special profile which is derived from four O‑rings arranged in a square crosssection.The particular advantage of the X‑ring is that it cannot roll or twist. The squeeze required to maintain an effective seal is also relatively low.The X‑ring is used in mechanical and automotive engineering, preferably as a static radial or static axial seal. Other applications are for linear or rotary motion of plungers, pistons, tappets, dampers and valve, bearing and piston rods, etc.
