01
Melting & Pouring
- Induction melting for clean, repeatable heats
- Chemistry verified before every tap
- Pouring temperature controlled ladle by ladle
Infrastructure
In-House Valve Casting Foundry
From the first melt to the finished casting, the metal inside every FLOEC valve is made and checked under our own roof.
- Induction melting
- Heat-wise traceability
- Carbon to super duplex grades
Core Capabilities
Foundry Capabilities
Casting quality decides how a valve body holds pressure for decades. Running our own foundry means every stage — melting, moulding, heat treatment, testing and finishing — is planned around the needs of the valves we build.
02
Moulding & Core Making
- Green sand and no-bake moulding
- Cores for complex internal flow passages
- Sand reclaimed and reconditioned for reuse
03
Heat Treatment
- Normalising, annealing and tempering by grade
- Solution annealing for stainless and duplex
- Furnace temperature records kept for each batch
04
Testing & Inspection
- Spectro chemical analysis of every heat
- Mechanical, hardness and microstructure checks
- RT, UT, MT and PT as the specification requires
05
Heat-Wise Traceability
- Heat number identified on every casting
- Test results linked through to the finished valve
- Records retained digitally for audits
06
Fettling & Finishing
- Gating removal, grinding and shot blasting
- Dimensional check before release to machining
- Visual inspection and dispatch clearance
Process Flow
From Pattern to Finished Casting
- 01Pattern
Patterns and core boxes prepared for each valve size and class.
- 02Moulding
Moulds and cores formed to hold tight dimensional tolerances.
- 03Melting
Metal melted and its chemistry confirmed before tapping.
- 04Pouring
Controlled pouring and cooling to sound, defect-free castings.
- 05Heat Treatment
Heat treatment matched to the material grade.
- 06Fettling
Castings cleaned, ground, blasted and checked.
- 07Inspection
Testing and NDT before release to machining.

Why It Matters
Why an In-House Foundry?
Shorter lead times
No waiting on outside foundries — castings move straight from our pour to our machine shop.
Quality from the first pour
Chemistry, heat treatment and soundness are controlled by the same team that answers for the finished valve.
Special grades on demand
Duplex, super duplex and high-alloy castings developed for project specifications without third-party delays.
One point of accountability
From melt to dispatch, every step is ours — one supplier, one set of records, one responsible team.
