Accessories for Rotary Valve

The rotary valve accessories for each individual unit are tailored to the customer’s product, application, and requirements. Some customers prefer the rotary valve to be easily and quickly opened for inspection and cleaning, while others never open the valve, once it is installed.

When customers deal with difficult, adhesive, or abrasive products, we pay extra attention to the valve construction, incorporating wear protection or a Smart Glide Finish surface treatment.

Additional security to prevent metal contact inside the valve is achieved with RotorCheck.

Extraction System FXS and FXL

To pull out the rotary valve, it comes standard with the FXS extraction system. This includes a claw coupling on the rotor shaft and a hinged side cover that swings completely away for easy access.

The FXL system is normally used for bigger rotary valves. It has a linear rail system to extract the valve and is an improved version of the FXS model.

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

The Rotor Contact Monitoring system is a new invention when it comes to safety related to rotary valves. Accidental contact between the Valve housing and the rotor can occur due to foreign bodies, incorrect installation/maintenance or too high a temperature/pressure in the rotary valves. This can generate metal-to-metal contact inside the rotary valve and thus cause scratches and damage to the rotary valve or contamination of the product. In the Rotorheck system the valve housing and the rotor are insulated from each other and conducting, electronic contact happens through metal-to-metal contact. The signal is sent to the customer’s control. The RotorCheck system also monitors cable breaks and the functions of the rotary valve. See more about the RotorCheck System in this video.
