Six Valve Families, One Casting Source
Every body and bonnet starts in our own foundry, so pattern changes, special alloys and non-standard face-to-face dimensions stay under our control.
Gate Valves
API 600 bolted bonnet, rising stem, flexible or solid wedge. WCB, LCB and CF8M bodies with 13Cr or full stainless trim.
DN50 - DN1200Class 150 - 2500
Butterfly Valves
Wafer, lug and double flanged. Concentric resilient seat or triple offset metal seat for steam and hot oil service.
DN50 - DN1200PN10 - PN40
Check Valves
Swing, dual plate and piston types. Bolted or pressure seal bonnet, optional counterweight and damper for surge lines.
DN15 - DN1000Class 150 - 2500
Globe Valves
T-pattern and Y-pattern for throttling and shut-off. Plug or parabolic disc, stellited seats for high temperature drops.
DN15 - DN400Class 150 - 2500
Control Valves
Pneumatic globe control valves with positioner, sized to your Cv and noise limits. Stainless steel valves for corrosive media.
DN25 - DN300Class 150 - 600
From Our Own Foundry to Your Flange
Most valve suppliers buy castings. We pour them. Owning the foundry removes the longest lead time and the biggest quality risk in valve manufacturing.
-
Step 1
Casting
Patterns, molding and pouring in-house. Spectrometer check on every heat before it leaves the ladle.
-
Step 2
Machining
Flanges, seats and stem bores machined on CNC centers. Face-to-face held to ASME B16.10.
-
Step 3
Assembly
Lapped seats, live-loaded packing on request, torque-controlled bolting in a dust-managed bay.
-
Step 4
Testing
API 598 shell and seat tests, then coating, marking and export packing with full documentation.
Every Valve Tested at 1.5x Rated Pressure
No sampling plans, no skipped serial numbers. Each valve holds shell pressure at 1.5 times its rating and seat pressure at 1.1 times before it gets a nameplate.
- EN 10204 3.1 material certificates traceable to the heat
- Hydro test report and dimensional report shipped with every order
- RT / UT / MT on pressure-retaining castings for Class 900 and above
- SGS, BV or your own inspector welcome at final inspection

Frequently Asked Questions
The questions buyers ask before the first purchase order, answered straight.
What is your minimum order quantity?
For standard specifications there is no minimum, one valve ships fine. For special alloys or non-standard face-to-face dimensions we quote a minimum casting batch, usually 4 to 10 bodies depending on pattern size.
Can you manufacture to our drawings or a sample?
Yes. We build new patterns in 3 to 5 weeks from your drawings, sample valve or even a worn valve you send us. Reverse engineering includes material analysis so the replacement matches or upgrades the original.
Which certificates come with the valves?
Every order ships with EN 10204 3.1 material certificates, API 598 hydro test reports and a dimensional report. CE marking under PED 2014/68/EU, fire safe API 607 and ISO 15848 certificates are available where the design is covered.
What are your typical lead times?
Stocked standard valves ship in 1 to 2 weeks. Production orders run 6 to 10 weeks including casting, and 12 to 14 weeks for pressure seal or Class 2500 designs. We confirm the schedule line by line with the quote.
Do you accept third party inspection?
Yes, SGS, BV, TUV or your own engineer. We send the inspection and test plan in advance, hold points included, and schedule the final test so witnesses see shell, seat and functional tests in one visit.
Send Your Valve List
Attach your MTO, datasheet or just the line list. A valve engineer, not a sales bot, replies within one working day with prices and lead times.
