The Spirax SafeBlocTM is a double isolation solution, with a unique space-saving design, offering reduced installation time and fewer leak paths.

Faster and easier to install than a traditional double block and bleed assembly, the Spirax SafeblocTM has an innovative design which incorporates two bellows sealed isolation valves and a bleed port in one compact assembly.

Easy to use and commission, the Spirax SafeblocTM can be installed without pipework modifications, into the space left by an existing single isolation valve.
