Description

API 603 Stainless Steel Valves – Corrosion-Resistant & Lightweight Solutions

Key Structural Features
✅ API 603/ASME B16.34 Design:
Precision Investment Casting: Stainless steel (CF8/CF8M), alloy steel, or duplex steel bodies for high-purity chemical, food, and cryogenic applications.
Lightweight & Cost-Effective: 30% lighter than API 600 valves, reducing installation and lifecycle costs.

✅ Zero-Leakage Sealing:
Integral Seat & Flexible Wedge: Self-aligning design ensures bubble-tight closure (API 598 Class VI).
PTFE Gasket & Packing: FDA-compliant for food-grade media, resistant to acids and solvents.

✅ Cryogenic & High-Temperature Ready:
Extended Bonnet: Optional design for LNG, liquid nitrogen, or ethylene service (-196°C).
Temperature Range: -196°C to +425°C (standard), higher grades available.

✅ Versatile Valve Types:
Gate, Globe, Check Valves: ASME B16.34 wall thickness for PN16~PN40 (Class 150~300) systems.
Compact & Hygienic: Smooth internal surfaces meet 3A/SMS sanitary standards for food/pharma.

Technical Specifications
Size Range: 1/2″~24″ (DN15~DN600).
Pressure Rating: Class 150~300 (PN16~PN40).

Body Materials:
Stainless Steel: CF8 (304), CF8M (316), CF3M (316L).
Alloy Steel: WC6, WC9 for high-temperature steam.
Duplex Steel: CD4MCu, UNS S31803 for chloride/sour environments.
End Connections: Flanged (RF/RTJ), threaded, or socket weld.
Testing: API 598 hydrostatic/pneumatic tests, PMI verification.

Industry Applications
Chemical & Pharma: Sulfuric acid transfer, reactor feed lines.
Food & Beverage: Dairy processing, CIP/SIP systems.
LNG & Cryogenics: Liquid nitrogen, oxygen, or argon control.
Pulp & Paper: Bleach plant, black liquor systems.
