Accessories for Rotary Valve

The rotary valve accessories are carefully adapted to each product’s specific properties, application, and requirements. In some situations, a rotary valve is needed that can be quickly and easily opened for inspection and cleaning, while in other cases, the valve never needs to be opened once installed.

For customers working with challenging, sticky, or highly abrasive products, we pay particular attention to the rotary valve’s construction, using wear protection or Smart Glide Finish surface treatment to enhance durability and minimize maintenance.

If an alarm is desired in cases of metal-to-metal contact within the rotary valve housing, we recommend the RotorCheck system, which signals if the rotor comes into contact with metal during operation.

Extraction System FXS and FXL

For rotor extraction, rotary valves are supplied as standard with the FXS extraction system. This includes a claw coupling on the rotor shaft and a hinged side cover that can be swung completely away from the rotor housing, ensuring optimal access.

For large rotary valves, we recommend the new FXL system. It consists of a linear rail system that allows the rotor to be extracted from the valve housing easily and safely with high precision. The FXL extraction system is an improved version of the FXS version.

Wear Protection

If products cause wear, then Coperion has many options for internal wear protection of the valve housing and the rotor. In this way the rotary valve achieves good protection and its longevity is also improved. The internal wear protection ranges from hard chromium plating (for products that cause little wear) to a ceramic coating (for products that cause considerable wear), of which the latter provides the best protection.

Smart Glide Finish (SGF)

Smart Glide Finish is a surface treatment of the stainless parts that are used when the rotary valve operates with sticky products and products that leave deposits. With Smart Glide Finish you achieve an anti-stick effect. In this way the product’s deposits in the rotary valve and on the rotor are minimised and the product can more easily ‘glide’ out of the rotary valve. Smart Glide Finish also helps reduce time spent on cleaning because the product layer in the rotary valve is reduced.

RotorCheck system

Rotor Contact Monitoring is one of the latest additions to operational safety in valve applications. Unintended contact between the valve housing and rotor can occur due to foreign objects, improper installation, inadequate maintenance, or conditions with excessive temperature or pressure in the valve. Such metal-to-metal contact within the valve can cause scratches and damage or even lead to product contamination. With the RotorCheck system, the valve housing and rotor are kept separated, so conductive electronic contact only forms during direct metal-to-metal contact. If contact occurs, a signal is sent to the control system. The RotorCheck system also monitors cable breakage and the valve’s overall functionality, providing extra safety and operational monitoring. See more about the RotorCheck System in this video.
