A Quick Overview of the Bonomi 171N

The Bonomi 171N Series is a reliable, multipurpose ball valve.  Not only does the 171N come in a range of sizes from 1/4”-4”, but it is also forged out of the highest quality brass.  The Bonomi Group is known throughout the valve industry as being a fierce competitor because of their solid construction, and incredible prices; all of which are essential qualities when looking for a versatile manufacturer.  Having started almost 200 years ago in 1928, Bonomi North America has focused a significant portion of its efforts to brass valves. However, they continue to diversify their offerings by manufacturing a wide range of valves using in bronze, stainless steel, lead-free brass, carbon steel and--now--even PVC. The lead-free valves, have recently surged as Federal mandates have stated that only lead-free valves are to be used in the processing of potable water.  Almost all of Bonomi products are manufactured in Italy, but are distributed internationally.

Inside the 171N

The Bonomi 171N series has a blowout proof stem and a chrome plated brass ball which only adds to its durability.  The product can accommodate temperatures reaching up to 366 degrees F and contains a secondary stem seal, which will assure that the valve is capable of enduring high heat. In addition, the Bonomi 171N has a steel handle, PTFE seats, a brass stem, and it’s full port and a threaded connection make it the perfect commodity valve for both commercial and residential use.  Furthermore, the Buna O-ring is fitted to the stem of the Bonomi 171N valve which provides the best possible protection against potential gas leakage that sometimes occurs with valves that are under heavy cycling or even low pressure applications.
