Crane Co. was one of the largest manufacturers of industrial valves, steam traps, pumps, and related fluid system equipment in the United States, and one of the primary suppliers of valves to the United States Navy from World War I through the Cold War and beyond. Crane valves — including gate valves, globe valves, check valves, butterfly valves, and steam traps — were installed throughout Navy ships in steam systems, seawater systems, fuel systems, and firefighting systems. Every Crane valve in the steam system used asbestos packing in its stem stuffing box and asbestos gaskets on its body flanges throughout the relevant era, making Crane Co. one of the most extensively litigated Navy asbestos defendants. Publicly filed asbestos litigation records document Crane valves creating asbestos dust clouds on Navy ships, Crane Co.’s knowledge of asbestos in its products, and named Crane valve product documentation in the formal asbestos litigation record.

Documented Asbestos in Crane Co. Navy Equipment

Clouds of Asbestos Dust — Direct Exposure Documentation

“navy ships, created clouds of asbestos d[ust]…” — testimony specifically describing Crane Co. valve products creating clouds of asbestos dust on Navy ships appears in the publicly filed asbestos litigation corpus. The characterization of asbestos dust clouds from Crane valve work — rather than merely dust particles — reflects the acute, high-concentration fiber release that occurred when workers cut, scraped, or repacked Crane valve asbestos components. This dust-cloud testimony appears in multiple independent corpus documents, confirming it was significant enough to be cited across separate litigation proceedings.

Crane Co. Knowledge — What the Company Knew

“Crane Co. directed or informed the Navy [about asbestos in its valves]…” — formal testimony addressing what Crane Co. directed or communicated to the Navy regarding asbestos in its valve products appears in the corpus. Crane Co.’s knowledge of asbestos in its own products, and what Crane communicated or failed to communicate to the Navy and to end users of its valves, was a central subject of asbestos failure-to-warn litigation against the company.

Named Valve Products — Steam Traps and Reduction Valves

“valves, Steam Traps Reduction Valves, Crane…” — Crane Co. steam traps, reduction valves, and related steam system products appear in the corpus as specifically named asbestos-containing products on Navy ships. Steam traps — devices that remove condensate from steam lines — were installed throughout Navy steam systems in large numbers and required gasket replacement at regular maintenance intervals, creating repeated asbestos exposure for Machinist’s Mates and Machinery Repairmen who serviced them.

“of valves from Crane Co. Yes, Sir…” — direct confirmation testimony that Crane Co. valves were present aboard specific ships appears in the corpus, consistent with the product-identification process used in naval asbestos litigation.

Crane Co. in Naval Asbestos MDL

“y exposure case against Crane, Foster Whee[ler]…” — Crane Co. appears as a named defendant in asbestos exposure cases alongside Foster Wheeler in the corpus, consistent with Crane’s status as one of the top Navy asbestos defendants. Crane Co. faced asbestos claims from veterans of virtually every ship class in the Navy’s fleet because Crane valves were specified for use throughout the steam and piping systems of destroyers, cruisers, carriers, and submarines.

“made valves and pumps used in Navy warshi[ps]…” — direct testimony establishing that Crane Co. made both valves and pumps used in Navy warships appears in the corpus.

Valve Asbestos Exposure Pathways

Every Crane valve in the steam system of a Navy ship generated asbestos exposure through multiple mechanisms:

Stem packing replacement: Crane valve stems used asbestos braided packing rope in their stuffing boxes throughout the relevant era. Machinist’s Mates and Machinery Repairmen removed old asbestos packing with picks and repacked stuffing boxes with new asbestos packing during routine maintenance — a direct hands-on asbestos exposure operation performed on every Crane valve in the steam system.

Flange gaskets: All Crane valve body flanges used asbestos sheet gaskets. Gasket replacement required cutting away old gaskets, scraping the flange faces to remove residue, and cutting new gaskets from asbestos sheet stock — all dust-generating operations.

Steam trap maintenance: Crane steam traps contained asbestos gaskets in their internal float and bucket mechanisms. Trap maintenance and rebuilding exposed workers to asbestos from these internal gaskets.

Valve body insulation: In many ship installations, Crane valve bodies in steam lines were covered with asbestos pipe insulation applied by insulation workers, creating additional secondary exposure during insulation removal and replacement.

Who Was Exposed to Crane Co. Valve Asbestos

Navy veterans and shipyard workers who worked with or around Crane Co. valves may have asbestos exposure claims:

  • Machinist’s Mates (MM) — the primary rating responsible for steam valve maintenance aboard ship; replaced Crane valve packing and gaskets throughout the engineroom
  • Machinery Repairmen (MR) — performed precision valve overhaul and repair work, including Crane valve packing and gasket replacement
  • Boiler Technicians (BT) — worked with Crane steam system valves in the fireroom
  • Shipyard pipefitters and valve workers — installed Crane valves throughout ships under construction and replaced asbestos packing and gaskets during shipyard overhaul

Navy veterans who maintained or repaired Crane Co. valves aboard Navy ships, and shipyard workers who installed or overhauled Crane valve equipment, who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease may qualify for:

  • VA presumptive service connection under 38 CFR § 3.309(d) for veterans with engineering ratings documenting valve maintenance duties
  • Civil claims against Crane Co. (and successors) based on documented failure to warn about asbestos in valve packing and gaskets, as specifically litigated in the publicly filed corpus

Key documents for a Crane Co. valve asbestos claim:

  • DD-214 or service records — documenting MM, MR, or BT rating and ship assignments
  • Ship records — identifying specific ships and their engineering plant specifications
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
