Zirconium Valves In Stock: Ladish B550 Ball & Check Valves (R60702) — A Surplus Buyer’s Guide
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.
What We Stock — Every Configuration
All specifications below are taken from the valves’ Ladish material tags and body stampings; MOP figures are the maximum operating pressures stated on each listing.

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.
Why Buy Surplus Zirconium From Us
- 24 valves across 7 configurations, in stock now — no mill lead time, no minimum-order negotiation. Orders typically ship within 3 business days.
- Tagged and traceable — heat numbers stamped on the bodies, original Ladish material and modification tags attached; we’ll photograph any tag on request before you buy.
- A 6-month warranty on every valve.
- A fraction of new pricing — from $1,599.99, versus new zirconium valve quotes that routinely run several times that with months of lead time.
Whether you’re standardizing sampling valves on a hot-acid line, holding critical spares for a urea-plant turnaround, or replacing one corroded valve without waiting a quarter for the mill, chances are the configuration you need is on our shelf.
