About PSI

Piping Specialties, Inc.

Our company was founded in 1975 with the mission of providing specialty valves and mechanical products and unsurpassed customer service to industrial users throughout the Northeast. Over the years our company has experienced steady, sustainable growth in both our customer base and product offerings. This growth has resulted in the recent establishment of PSI Controls, a division of Piping Specialties dedicated to system design, sales, and service of process controls and instrumentation.

With offices in Danvers, MA and Portland, ME, we are geographically well-positioned to serve all of the Northeast. Drawing from our extensive inventory, we can provide one day shipment without expensive expediting or air freight charges.

PSI delivers our products and services through our 3 operating divisions:
  • Piping Specialties, Inc.: valves and mechanical specialties;
  • PSI Controls: automated valves and process instrumentation & controls;
  • PSI Services: valve automation, valve and instrument repair, calibration, and turnkey installation and field services.
