Product description

This custom stainless steel valve housing is manufactured by composite turning and milling. The square flange plate, multi-step outer shoulder and tiered inner bore are processed in sequence to ensure perfect concentricity between all inner and outer circular features.

Chenrong Precision is capable of composite machining for complex stainless steel valve bodies. The square flange with four mounting holes enables stable bolt-on installation. Tiered inner cavities are designed for sealing assembly of valve cores and seals. Bright polishing optimizes surface smoothness for fluid flow and sealing performance. We can adjust flange size, step dimensions, inner cavity depth and hole layout according to your drawings.

Product Features

• Composite CNC turning & milling for integrated square flange and stepped shaft body
• Multi-tier concentric inner bore for valve core and sealing fitting
• Square flange with 4 precision mounting holes for stable assembly
• Bright polished surface, smooth inner cavity for fluid transmission
• High pressure resistance and long-term anti-corrosion performance

Product Advantage

Our workshop has combined turn-mill CNC machines to complete this complex part in fewer clamping times, reducing cumulative tolerance error. Every finished part will undergo concentricity and dimensional inspection. We provide drawing review and machining optimization suggestions before production, supporting prototype validation and continuous mass supply for industrial fluid equipment manufacturers.

Application

• ✅ Fluid control valve housing for industrial liquid and gas pipelines
• ✅ Hydraulic pressure regulating component for power control systems
• ✅ Process pipeline fitting for chemical and water treatment equipment
• ✅ Pressure chamber shell for precision pressure testing instruments

FAQ

• Q1: What pressure rating can this stainless steel valve housing withstand?

         A1: It depends on wall thickness and material. 316L version can work steadily under medium pressure; we can adjust wall thickness for higher pressure requirements.

• Q2: Can we customize sealing grooves inside the cavity?

         A2: Yes, we can machine O-ring grooves of different sizes on inner steps to meet your sealing requirements.

• Q3: What is the difference between brushed finish and bright polishing?

         A3: Bright polishing delivers smoother surface for better sealing; brushed finish hides minor machining marks and reduces fingerprint retention.

• Q4: Can you modify the size of the square flange?

         A4: All dimensions including flange width, hole pitch, step diameter and cavity depth are fully customizable.

• Q5: What is your QC process for stainless steel valve parts?

         A5: We inspect raw material first, then check key dimensions and concentricity after machining, surface inspection and passivation treatment before packing.
