Product Description

The Foxboro Company (Foxboro, Massachusetts) was through the asbestos era the dominant American supplier of industrial process instrumentation and control-loop hardware — pneumatic (3–15 psi) and electronic (4–20 mA) pressure, differential-pressure, level, and flow transmitters; strip-chart and circular recorders and pneumatic controllers; orifice-plate flow elements and DP flowmeter assemblies; and, through the Foxboro Valve Division, the E-Series and Stabilflo lines of pneumatically actuated control valves used to modulate steam, hot oil, refinery process streams, boiler-feedwater, and chemical process flows.

Foxboro instrumentation and control valves are named in publicly filed U.S. asbestos personal-injury and wrongful-death litigation. Plaintiffs alleged that Foxboro process instrumentation and control valves were specified with:

  • Compressed asbestos-sheet gaskets at transmitter housings, differential-pressure manifold flanges, orifice-flange taps, and control-valve body-to-bonnet joints.
  • Asbestos-containing stem packing — braided chrysotile packing installed in Foxboro control-valve stuffing boxes against rising plug stems.
  • Asbestos-containing thermal insulation applied to hot-service instrument lines, orifice-flange assemblies, and control-valve bodies on high-temperature steam and hot-oil service.

Workers Exposed

  • Instrument mechanics and I&C technicians removing Foxboro transmitters and controllers for calibration, replacing transmitter and manifold gaskets, and disturbing orifice-flange gasketing during flowmeter rebuilds.
  • Pipefitters and steamfitters installing and tying in Foxboro control-valve bodies on process piping and repacking control-valve stuffing boxes.
  • Refinery process operators and turnaround maintenance crews pulling Foxboro control-valve bonnets during scheduled refinery turnarounds.
  • Power-plant control-room mechanics servicing Foxboro boiler-feedwater and steam-throttling control valves on utility service.
  • Chemical- and pharmaceutical-plant maintenance mechanics overhauling Foxboro E-Series and Stabilflo control valves on hot and corrosive service.

If You Worked With Foxboro Instrumentation and Control Valves

If you installed, calibrated, or rebuilt Foxboro Company transmitters, recorders, controllers, or E-Series / Stabilflo control valves during the asbestos era — and have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related illness — you may have legal rights.
