Tierney & Dalton Associates began its journey by bringing exceptional service and more than 30 years of industry experience to the New England PVF Market. It was established in June 1986, when we saw a need to provide competitive sourcing for both commodity items and some of the industries more hard to find items. As we became very good at finding just about anything, we began to provide one stop shopping for industrial piping products to jobsites not only in New England but throughout the country.

In 2006, Tierney & Dalton Associates, Inc. merged with Advantage Valve, Inc. This combined team brings over 60 years of experience to our customers and underscores our commitment to “unparalleled service” by providing the highest level of technical expertise.

Over our 30+ years, we have expanded into valve automation, high purity piping products, metal cutting & polishing, fasteners, fabrication and much more. In today’s marketplace it is easy to get lost in the “mega superstore” mentality of PVF supply houses. Most customers find it refreshing to choose Tierney & Dalton because our main focus is to complete customer satisfaction.
