For a wide range of valves, there are also a large number of possible materials. Depending on the fitting, these materials are selected based on standards and/or applications. Factors such as strength, chemical and thermal resistance as well as manufacturing processes play a major role in the choice of material.

Forged components

The handles of the TX are made of forged aluminum and practically indestructible. Brittle fractures of the hand grip cannot occur even when the coupling accidentally falls.

Precision casting

The highly reproducible dimensions and a fi ne, smooth and seamless surface fi nish set new quality standards.

Duplex steel

Components subject to the greatest stress are made of duplex steel which combines the high mechanical strength and excellent corrosion resistance of different steel grades.

PTFE

High-grade PTFE seals provide low friction for enhanced coupling performance, and the universal chemical resistance reduces maintenance.

O-rings

Different seal materials are available for various applications: all common materials such as FKM, EPDM, NBR, FFKM, etc. can be used.

Corrosive media call for special fittings which provide suitable surface protection.

For protection against aggressive media such as acids and lyes, highly chemical-resistant fluoroplastic coatings are used. These include PTFE, FEP, E-CTFE, ETFE, or PFA.

This coating is applied to areas that come into contact with the media. Unfortunately, not all parts of a coupling assembly can be coated.In this case highly chemical-resistant materials like nickel-based alloys (e.g. Hastelloy®) are used.

Wear protection

The mechanical properties of parts subject to the greatest dynamic loads are enhanced by a special process which improves the surface hardness, strength and ductility while retaining the corrosion resistance of the original material. This signifi cantly increases the lifetime of the coupling.

Hard anodized

Aluminum couplings are optionally available with a hard anodized fi nish. The resulting high surface density and hardness provides optimum corrosion and wear resistance, especially valuable for exposed use in offshore applications.

Anodization

Activation components such as locking-levers and handle-adapters are anodized to increase their corrosion resistance.

Powder coating

The TX handles are treated with a highly resistant powder coating, which is available in all colors to customer order.

Reduced wear

To increase the coupling lifetime, all components subject to dynamic loading are coated with an additional PTFE-based high performance grease. This is universally chemically resistant and suitable for use over the entire temperature range of the coupling.

Corrosion protection

To simplify coupling disassembly for maintenance work, screws are coated with a special lubricant during factory assembly so as to prevent galling after a long period of use. This is especially important for stainless steel screws in aluminum housings.
