If your plant runs hot acetic acid, formic acid, urea synthesis, or any of the aggressive services where stainless steels and even nickel alloys corrode away, you already know two things about zirconium valves: nothing else lasts like them, and buying them new is painful — mill-run lead times stretch months, and pricing reflects one of the most expensive corrosion-resistant metals in commercial use.
That’s why surplus matters. We currently have 24 zirconium valves in stock across 7 configurations — Ladish B550 ball and check valves plus a pneumatically actuated Setpoint unit, every one with its wetted parts in UNS R60702 commercially pure zirconium, tagged, traceable, and ready to ship with a 6-month warranty. Prices start at $1,599 — a fraction of new-mill cost.
Why Zirconium?
Zirconium occupies a niche at the top of the corrosion-resistance ladder. In hot organic acids — acetic and formic acid service above the temperatures where 316 stainless pits and crevice-corrodes — and in urea-plant carbamate service and many hot mineral-acid environments, R60702 zirconium survives conditions that consume stainless steels, duplex grades, and many nickel alloys. That performance is why acetic-acid producers, urea plants, and specialty chemical processors specify zirconium valves despite the metal’s cost: the valve outlives generations of cheaper-alloy replacements and eliminates the unplanned outages that go with them.
As with any exotic-alloy component, verify material compatibility against your specific process chemistry, concentration, and temperature before installation — we’re happy to share the full nameplate and tag data from any valve to support your materials review.

The Workhorse: Fifteen Matched 1″ Class 300 Ball Valves
The deepest pool in the inventory is the 1″ Class 300 Ladish P235-V630-DR02-E10N — fifteen matched valves. For a maintenance planner, a matched surplus pool this size is the real prize: standardize a line’s instrument-isolation and sampling valves on one part number, install from stock, and keep identical spares on the shelf for turnarounds — all for less than a single new zirconium valve typically costs after the mill queue.
Ball Valves: API 607 Fire-Safe, B16.34/608 Construction
The Ladish ball valves in this inventory are API 607 fire-safe designs built to ASME B16.34 and API 608, with R60702 zirconium bodies, stems, and balls, glass-filled PTFE seats, RF/PTFE seals, and graphite gaskets. Body stampings carry the heat number, and the Ladish modification tags (with figure numbers and fastener specs) are still wired to the valves — the traceability your QA department will ask about is physically on the hardware.
The Check Valve: All-Metal to 700 °F
The single most capable piece in the inventory is the 3″ Class 300 Ladish B550 check valve (EHE D pattern): body, obturator, and seat all in R60702, rated 589 PSI at 700 °F — no soft parts to limit temperature — built to B16.34/594 with a graphite gasket. It weighs 145 lbs of solid zirconium. If a hot-service check valve failure has been holding a line hostage, this is the one-in-stock solution.
Automated Service: the Actuated Setpoint 2″
For automated duty there’s a Setpoint 2″ Class 300 ball valve in ZR702 zirconium (ASTM B493) with its pneumatic actuator already mounted — an unusually cheap entry into actuated zirconium at $1,599.99, given that the actuator alone would cost a meaningful fraction of that new.
Zr702 vs. Zr705 — and Why These Are R60702
ASTM B550 covers zirconium bar and forgings in two commercial grades. R60702 (Zr702) is commercially pure zirconium; R60705 (Zr705) adds 2–3% niobium for roughly half again the strength at the cost of some corrosion margin and weldability. Valve bodies are overwhelmingly produced in 702, and every Ladish and Setpoint valve on this page is R60702 body and trim. For pressure-boundary duty at Class 150/300 ratings, 702’s lower strength is already accounted for in the B16.34 rating tables — you give up nothing by not having 705 in a valve.
Where Zirconium Beats Hastelloy and Titanium
Zirconium is not a general-purpose upgrade; it is a specialist with a narrow, valuable window:
- Hot concentrated acetic and formic acid — the classic service. Zirconium is essentially inert across all concentrations to boiling, where stainless pits and titanium suffers in anhydrous conditions.
- Sulfuric acid to ~70% at boiling — corrosion rates a fraction of Hastelloy’s. Above ~70% concentration the oxide film breaks down; do not use it there.
- Hydrochloric acid, all concentrations, boiling — one of very few metals that survives reducing HCl, where titanium fails quickly. Watch for ferric or cupric ion contamination, which attacks zirconium.
- Alkalis to 50% at boiling — handles hot NaOH where titanium is limited.
- Do not specify zirconium for hydrofluoric acid (any concentration), wet chlorine, aqua regia, or ferric-chloride-bearing streams. That is Hastelloy or tantalum territory — see our Hastelloy C-22/C-276 inventory.
The economics follow the metallurgy: a new zirconium ball valve is a 20-plus-week mill-order item priced like an exotic, because it is one. Pickling lines, acetic/terephthalic acid plants, and specialty chemical producers spare these valves aggressively — which is exactly why a tested surplus pool with matched units matters.
What We Verify on a Surplus Zirconium Valve
- Alloy confirmation — body and closure markings against B550/B16.34 (R60702, class, size, heat) and XRF verification on request.
- Seat integrity — full open/close cycling and bubble-tight seat check on ball valves; free swing and reseat on checks.
- Stem and packing — smooth quarter-turn travel, no packing weep, live-load hardware present where fitted.
- Fire-safe hardware — API 607 tag data intact on the fire-safe Ladish units; graphite secondary seals undisturbed.
- Bore and sealing faces — flange faces unmarred, bore free of mechanical damage; zirconium’s protective oxide means clean surplus bodies do not degrade in storage.
Zirconium Valve FAQ
What does “Ladish B550” mean on the nameplate?
Ladish is the valve maker (Ladish Valves, Houston); B550 is the ASTM material specification for the zirconium body forging. Together they identify a pressure-rated valve whose wetted parts are R60702 zirconium, not a coated or lined substitute.
Are these lined or solid zirconium?
Solid. Body, ball, and stem are wrought/cast zirconium per B550/B752 — there is no liner to breach and no substrate to protect, which is why surplus units with clean bores are functionally equivalent to new metal.
Can I install a Class 300 valve in a Class 150 line?
Yes — flange drilling differs, so confirm your mating flanges, but a higher class in the same size is a common way to buy margin from surplus stock when the price difference is small.
How does surplus pricing compare to new?
New zirconium valves in these sizes routinely run several times our listed prices with mill lead times measured in months. Surplus from a tested, matched pool ships in days. If you need a quantity for a project or want spares matched to units already installed, contact us — the fifteen matched 1″ Class 300 units above are the deepest single pool of surplus R60702 valves we have seen offered anywhere.
Why Buy Surplus Zirconium From Us
