Material Composition:
- SS316: C≤0.08%, Cr 16–18%, Ni 10–14%, Mo 2–3% - enhanced pitting and crevice corrosion resistance
- SS316L: C≤0.03% low carbon variant, superior weldability and intergranular corrosion resistance for welded assemblies
Manufacturing & Quality Control
Production Workflow: Wax pattern injection → ceramic shell building → vacuum investment casting → 5-axis CNC machining → pickling/passivation (ASTM A380) → CMM dimensional inspection → hydrostatic pressure testing at 1.5× nominal pressure.
Key Features & Benefits
Engineering Advantages:
|
Corrosion Resistance: |
SS316/316L molybdenum content provides resistance to chlorides, acids, and industrial chemicals |
|
Pressure Integrity: |
Wall thickness designed per ASME B16.34; hydrostatic tested to ensure zero leakage at rated pressure |
|
Flow Efficiency: |
CNC-finished internal passages minimize turbulence and pressure drop |
|
Customization: |
OEM/ODM supported, custom bore diameters, port angles, actuator mounting pads per customer drawings |
Operational Benefits:
- Extends valve assembly service life in chemical processing and marine environments
- Reduces system downtime through reliable sealing surface geometry (Ra ≤3.2 μm on seat areas)
- Compatible with global standard actuators and valve trim components

FAQ
|
Q1: |
Can you produce customized Valve Body according to our drawings? |
|
A1: |
Yes, we support full OEM and ODM services. Our engineering team reviews your drawings for manufacturability (DFM analysis) and produces custom sizes, materials, and flow channel structures (L-type or T-type) to your exact specifications. |
|
Q2: |
What stainless steel materials can you provide? |
|
A2: |
We offer SS304, SS316, SS316L, and other custom stainless steel grades. SS316 and SS316L are recommended for corrosive environments due to their molybdenum content, while SS304 provides cost-effective performance for general industrial applications. |
|
Q3: |
What connection types do you support? |
|
A3: |
We manufacture valve bodies with threaded (BSP, NPT, BSPT, Metric), flanged (ANSI, DIN, JIS), and welded (BW, SW) connections. Mixed connection types on different ports can also be customized. |
