Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Hydraulic valves rose 3.2% over the last 12 months, but all of its main inputs rose faster: copper and brass mill shapes +30.0%, steel mill products +27.6%. That cost pressure may still pass through to prices.

Since 2016, this index has followed the hot rolled steel price index about 3 months later and moved only a small fraction as far as it over a year.
Over the 12 months to Sep 2026, the hot rolled steel price index rose 15.0% and this index rose 3.2%.
A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Fluid Power Valves (BLS series WPU114302), published by BLS. Base Period: the index value published for September 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
Used in equipment-service and machine-build contracts that buy valves. A valve is machined metal plus assembly and test, so a clause tied to a raw metal series can follow the wrong cost.
Divide the current value of BLS series WPU114302 (Fluid Power Valves) by its value at contract signing, then apply that ratio to the fluid power valves part of the price. A usable clause also names an averaging window, a rule for revised values and missing months, and a cap.
Escalake tracks US PPI — Fluid Power Valves, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
