3/8" Certified Safety Valve
- Product description
Comes with factory certification that the valve will open in the event of a boiler over-pressurizing. Set to open at 1.8 bar. This is the most common size thread, but is by no means used in all makes and models; some use a smaller 1/4" version and some a larger 1/2" version.
Each valve has factory printed certifications included in the packaging.
