Carbon steel nickel-plated joint through-hole precision CNC machined knurled valve connection component

Valve Body / Valve Block / Valve Seat

1. Core User Requirements

• Smooth operation, no external leakage, no internal leakage
• No cracking under high pressure, no deformation at high temperature
• Resistant to medium corrosion, no contamination
• Long service life, low failure rate

2. Key Customization Specifications
   (1) Flow Path Design

• Flow path surface finish: Ra0.8 ~ Ra0.2
• No dead zones, no burrs, prevents jamming by impurities
• Low flow resistance, stable flow rate

• Working pressure → Design pressure → Burst pressure
• Standard: Burst pressure ≥ 3–4 × working pressure
• Temperature range: -40℃ ~ 150℃ (general); special materials for higher temperatures

• Seal groove dimensions: depth, width, roughness
• Mounting surface flatness and parallelism
• Bolt hole positional tolerance: prevents uneven compression and leakage

• Compatible with fluid media, no rust, no precipitation, no chemical reaction
• Fatigue resistance and stress corrosion resistance

3. Typical Applications

• Pneumatic valves: solenoid valves, throttle valves, directional valves, pressure relief valves
• Hydraulic valves: relief valves, check valves, servo valve blocks
• Water / gas valves: water heaters, wall-hung boilers, sanitary ware
• Medical / analytical instruments: micro valves, diaphragm valves, chromatography valves

4. Professional Material Selection

• General water / air service: brass, bronze
• High-pressure hydraulic systems: carbon steel, forged steel, alloy steel
• Acid-alkali / chemical / seawater environments: 316L, duplex stainless steel, Hastelloy
• Food, pharmaceutical & ultra-clean applications: electrolytically polished 316L
