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.

We produce hoses and technical hose products for many well-known engine and vehicle manufacturers in dimensions from 10 to 250 mm at any length and various working pressures. COUPLING Pressure-resistant hose elements as a straight connector or de-coupling element in pipelines for pressures up to 20 bar. SPIRAL HOSE Suction and pressure-resistant versions from -0.9 bar to +20 bar, with or without cuffed ends. Can also be laid in narrow radiuses. CHARGE AIR HOSE As an industrial hose, hose elbow or corrugated spiral hose for suction and pressure lines. As bellows with external metal rings in the pressure area. HOSE ELBOWS Stable shape connecting elements, either for suction and/or pressure in any geometry. Other versions and dimensions on request.

Bonded seals are a cost-effective solution for bolt/thread sealing. They offer reliable high and low pressure sealing capability and are able to perform in a wide range temperatures. The seal itself is made up of a disc consisting of a metallic ring and a rubber sealing pad bonded together.

A single-acting sealing element consisting of a U-shaped Turcon® ring and a metallic V-shaped finger spring. The special flanged heel prevents the seal from rotating/twisting and the short and heavy dynamic lip offers reduced friction, resistance to aging and a good scraping effect even in highly viscous media.
