Bypass valves without the usual problems

Mazzoni’s construction of an unloader with a microswitch is something that sets us apart from other products on the market.

Mazzoni manufactures unloader valves both with and without a microswitch. Our microsensor is located on top of the valve to avoid any possible contact with water. This one change allows our product to avoid 80% of the usual problems associated with unloader valves.
