Metal ring - 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.
