DENMARK: Danfoss has released a new safety valve offering reduced capacity, high reliability, and high-pressure for applications with CO2 and synthetic oils.
As well as offering pressure settings from 28 to 65 bar, the new SFA 10H also comes in new variants with NPT connections in selected pressure settings and bundled kits.
With its focus on preventing leaks, the SFA 10H is said to provide perfect reseating after release, and keeping a stable set pressure over time. The EPDM O-ring is said to guarantee a tight sealing and the springs are designed with a low-stress level to ensure a stable set pressure over time. The SFA 10H can be delivered with a standard pressure setting certificate or TÜV pressure setting certificate.
Danfoss says that sizing and selection are simple using the Coolselector2 software and weld nipples are available for easy mounting and installation.
DSV 10 change-over valve
The new DSV 10 change-over valve has multiple connection options, being offered in both G-thread and NPT-thread variants. It comes with a position indicator reducing the risk of errors during service and maintenance. Furthermore, blind plugs are available for system pressure testing and a reducer for perfect positioning.
