Reducing maintenance costs with thermoglide™

Friction within pressure relief valves is the enemy of continuous, trouble-free operation. Our Thermoglide™ technology is the solution. Designed to eliminate the risk of seizing or galling, Thermoglide™ improves the gliding characteristics of internal parts. This enables the valve to achieve its full lift and re-seat point within the fastest possible time.

Reduced friction lowers the risk of maintenance outages and unplanned downtimes. Thermoglide™ is available on the Starsteam V Series and Stareco 76E Series pressure relief valves.
