Inside Bautu's Manufacturing Facility
Where Every Valve ls Designed, Cast, Machined, and Tested Under one Roof
A walk through our 50,000 m² integrated plant: design center, foundry, CNc workshop, assembly & testing, OC-every step under our own control.
— 01 ● Plant layout
A 50,000m’ Plant Built as One Continuous Workshop
Unlike traditional valve suppliers who split production across multiple sites or subcontractors, our facility runs as a single
connected workflow, Here is how the 50.000m? breaks down – and why that matters for your project.
Foundry
8.000 m²
CNC Machining
15.000 m²
Heat Treatment & Assembly
10.000 m²
QC & Pressure Testing
4.000 m²
Warehouse Shipping
8.000 m²
Engineering Office
3.000 m²
Outdoor Storage
2.000 m²
All zones connected by internal logistics – castings travel from foundry to OC without leaving our gates
— 02 ● Foundry
From Molten Metal to Finished Casting - All Under Our Roof
HEAT TREATMENT IN PROGRESS
Stainless steel valve castings emerging from our heat-treatment furnace
Our 8,000m² foundry is the foundation of BAUTU’s 30. year heritage.
🔩 We specialize in stainless steel casting and valve manufacturing-one material, perfected over three decades.
Most Chinese valve suppliers outsource their castinas to small workshops-invisible, uncontrolled,inconsistent quality. We do the opposite. From the first pour of molten metal to every finished valve body, every step happens inside our own plant.

Not Just Manufacturing -We Design Valves Too
At BAUTU, every valve is designed in our engineers’ computers before it is manufactured on our shop foor Our engineering team uses SolidWorks 3D modeling software, combined with decades of valve design experience, to provide:
📐 Standard product 3D drawings – API/ DIN /ASME catalogues on file
✏️ Customer drawing review & optimization – engineer-to engineer dialogue
🔧 OEM custom valve design – from concept to production
🗒️ Specialized service selection support – high temperature,corrosive, sour service
SolidWorks
Industry-standard 3D modeling
OEM Ready

FACTORY WALKTHROUGH
"One Continuous Take-See Our Integrated Production Line"
From foundry pour to CNC machining to pressure testing – no cuts, no staging

— 05 ● Quality Control
From Casting to Shipment - Every Valve Passes Three Stages
🔬
STAGE 1
Casting Inspection
After castings leave the foundry, experienced inspectors visually check & sample-measure each piece.
📐
STAGE 2
Machining Inspection
After CNC machining, sealing surfaces & mating dimensions are checked per piece
💧
STAGE 3
Assembly & Pressure Test
100% hydrostatic test – shell, seat & sealing performance verified before shipment
— 06 ● Team & Capacity
The People Behind Every Valve
300+
Engineers, technicians & workers
Inside our 50,000m² plant, more than 300 engineers, technicians and front-line workers – senior craftsmen mentor newer staff, and experience is passed down on every single valve.
They aren’t a data point. They are the real makers of every BAUTU valve.
