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

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.
