Sliding Ring

These sliding rings are the solution for designs which only allow room for a small or low housing, but require an operating pressure up to 80 Mpa. They are ideal for retrofitting into existing O‑ring grooves

The main applications are liquids at very high pressure. This seal can also be used for gases if the maximum operating parameters are restricted.

Face seal used for rotary and oscillating motion in pipe joints and rotary actuators. Used at low to high pressure and low speed

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.
