How Flowserve makes money
It earns revenue by selling custom-engineered and pre-configured pumps, valves, seals and actuators through direct sales, distributors and sales representatives. It also earns recurring aftermarket revenue from replacement parts, repairs, diagnostics, retrofits and maintenance services on its installed equipment.
What Flowserve does
Flowserve is a Texas-based industrial manufacturer, with roots going back to 1790, that supplies flow management equipment. It reports in two segments. The Flowserve Pumps Division (FPD) sells custom engineered and pre-configured pumps, pump systems, mechanical seals (including gas-lubricated seals for pipelines) and auxiliary systems. The Flow Control Division (FCD) sells isolation and control valves, valve automation, actuators, positioners and switches under brands such as Valtek, Argus, Worcester, Limitorque and Durco. Both segments also sell services, including installation, commissioning, spare parts, repairs, advanced diagnostics, re-rates, upgrades, retrofits and field machining. These services tie revenue to the installed base of equipment. Its main customers are in oil and gas, power generation, chemicals and water management, plus general industries such as pharmaceuticals, mining, food and beverage, steel, and pulp and paper. It sells in the Americas, Europe, the Middle East, Africa and Asia Pacific.

What is Flowserve worth?
On an owner-earnings DCF, Flowserve's most-likely value is about $65 versus a recent price near $72 (10% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$37) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.
Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
