Bezzera safety valve, 1.65 bar with built-in anti-vacuum — 1/2″ thread, CE certified
Part no. ET-100188
Safety valve for Bezzera, opening at 1.65 bar with a 1/2″ connection, with a built-in internal anti-vacuum and CE approval (compliant with directive 2014/68/EU). It combines two protections: it releases excess pressure and, on cooling, prevents a vacuum in the boiler. Compatible with Bezzera.
It fits Bezzera boilers with a 1/2″ connection. Before ordering, confirm the opening pressure (1.65 bar) and the built-in anti-vacuum against the current valve.
Why is it dual-function?
As well as releasing excess pressure, the internal anti-vacuum lets a little air in when the boiler cools, preventing a vacuum that would pull on the seals.
What certification does it carry?
It is CE certified, compliant with directive 2014/68/EU, and the opening pressure is fixed and factory-sealed.
Can I adjust the pressure?
No. The certified version has a fixed pressure and must not be opened or altered, in line with the applicable standard.
How do I order?
Simply request a quote with the pressure and thread, or a photo of the current valve. We ship to Portugal and throughout Europe.
