Case Study

Chocolate processing

Background

This customer’s facility in Germany processes chocolate products, and they had experienced historical issues with butterfly valves for
critical processes whereby the valves were failing prematurely and replacement parts were only available on a long lead-time. Additionally they required higher performing sealing solutions for hygienic connections throughout the process, requiring a superior material that would provide an effective seal while being resistant to aggressive process and cleaning media.

Solution and Benefits

Unsatisfied with the existing butterfly valves as well as their seals for hygienic connections, the customer worked closely with Garlock to organize trials of both GAR-SEAL® PTFE Butterfly Valve (DN 80-150) as well as GYLON BIO-ASEPT® seals. With a key focus on process efficiency and reliability, the trial proved to be a great success with zero failures and no unscheduled downtime. Garlock’s products have now been chosen throughout the process because of their excellent performance, extended lifetime and compliance with required industry standards such as FDA and EN1935. The short lead-time and strong service support from Garlock also means that the customer is now able to order the products only when required thus reducing the need for additional inventory and avoiding associated costs.
