Case Study
Valve Manufacturer for CSP
Industry
Energy – Solar power plants
Customer
The customer is a valve manufacturer focused on metal-to-metal sealing valves. The customer’s business areas include chemical industries and solar power plants.
Background
The customer produces valves for solar power plants. Concentrated Solar Power (CSP) systems generate energy by heating up a media with mirrors. The heated media can store the energy so that the power plant can convert this heat into electricity over an entire day.
Challenges faced
The starting point was that the customer had problems with a competitors gland packing product. The packing’s lifetime was very short, especially in the tower. Also, the supplier’s support did not meet the customer’s expectations. For this reason an alternative packing with a longer lifetime and a supplier with better customer support was sought.

1. HTF: Molten salts
2. Design Pressure: 150 bar
Working Pressure: 40 bar

Solution and Benefits
The customer came into contact with Garlock. As the best solutions POWERPACK 9020-HMS, 9021-HMS and 1220-MS were presented by Garlock. In addition FLEXSEAL® Spiral Wound Gaskets with THERMa-PUR® were offered, which withstand extremely high temperatures.
It was also important for the customer that the packing sets are approved for the Chinese market. After ensuring that all requirements were met, the Garlock solutions were implemented.
Current status: the sets are still in use after 2 years and the design is the standard for the application.
