Westfälsche Drahtindustrie GmbH uses highly efficient plant technology at its Salzgitter site to produce cold-ribbed reinforcing steel (CR) in rings and coils, as well as structural steel mesh. Thanks to special wire rod primary material for our CR products, which we have developed in close cooperation with our suppliers, our reinforcing wire achieves first-class technical values, particularly in terms of elongation and the Re/Rm ratio The advantages for the user: easy processing and dimensional accuracy of the hangers. Seamless quality monitoring from the wire rod to the finished product by our own quality centre and our external monitoring centre (MPA Dortmund) guarantees the highest level of lasting quality and safety.

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.

XXL O‑rings are typically used as static radial or static axial seals in mechanical, power plant, plant and heavy equipment engineering. The special stagevulcanization production technology is also suitable for single or small lot production of smaller O‑rings with a nonstandard inside diameter.

The MANOY® backup ring is a solid or split ring which is rectangular or profiled in section. Various sectional profiles and sizes are available in standard or customized versions. MANOY® backup rings can also be used in dynamic applications – positioned on both sides of the O‑ring for alternating pressure.

According to DIN2353 for pipe connections up to 60 bar

A snap or retaining ring is a fastener or retaining ring that consists of a semi-flexible metal ring with open ends that can be snapped into place. It fits in a groove on a shaft or inside a bore and locates the shaft axially in one direction.

Circlips and Locking Rings consist of a semi-flexible metal ring with open ends that can be snapped into place. They fit in a groove on a shaft or inside a bore and locates the shaft axially in one direction.

As high-performance plastics, we mainly use PTFE with various fillers such as bronze, glass fiber or carbon. For special applications, we also offer sealing rings made of PAI or PEEK.

We have specialized in R-rings SH according to DIN 34109 / DIN34110 / DIN34118. In addition to the hook joint (SH), we mainly supply with straight joint, overlapped joint (SU) or gas-tight joint (SG or SW).

When to use piston rings? When piston rings with excellent wear properties are required When simple assembly is of great importance When high edge loads occur When tailor-made solutions based on iglidur® materials are required When not to use piston rings? When the piston rings should seal simultaneously When different diameters should be covered by one part Before: with piston rings: Why complicate things when it can be done differently? Replace elaborately stamped PTFE tapes with a single clip-on guide ring, such as in lifting elements, control valves and fittings. We offer iglidur® piston rings made of freely selectable materials for a wide range of applications.
