castel safety valve manufacturer

The compact dimensions and use of high-performance materials places the 3061E valve from Castel as a reliable safety device suitable for installation in all refrigeration systems, especially in CO2 transcritical applications.

Transcritical applications not only feature extremely high working pressures, up to 150bar; they also show very high temperatures at the compressor discharge line. This brand new safety valve perfectly complies with these extreme conditions, since it can reach set pressures up to 150 bar and 150°C working temperatures!

Safety valves type 3061E guarantee repeatable performance. This means that, after the valves haveoperated, open/close, the initial setting conditions are maintained.

All Castel safety valves are equipped with NPT inlet connections. At the outlet, depending on the type, they are provided with SAE flare or thread connections. Each safety valve is individually tested and adjusted. Each safety valve has a unique serial number which is also mentioned on the supplied PED certificate.

The new 1427E and 1428E solenoid valves are for 120 and 140bar pressure (1740 and 2031 PSI), respectively. The new safety valve, the 3061E, has a set pressure of 150bar (2176 PSI). Castel introduced other CO2 valives at Chilventa in 2018.

The entire range of Castel CO2 valves is suitable for applications like heat pumps, industrial refrigeration, commercial and industrial air conditioning, refrigerated transportation and supermarket installations.

“With these product ranges Castel is now the ideal partner for air conditioning and refrigeration applications, with no limits for the new refrigerants both today and in the incoming years,” said Application Manager Stefano Matti.

However, Castel doesn’t just offer standardized solutions. “For special applications, or items not included in the existing general catalogue, Castel is able to design and manufacture a customized solution to meet a specific application,” Matti stressed.

“Castel engineers can work closely with the R&D department of [our] clients and in this way it is possible to understand and study in detail the application in order to develop new technologies or new solutions, not yet available on the market,” he explained. “This essential synergy is beyond the standard supplier-client relationship and is more like a reliable and proactive partnership with a focus on the common growth.”
