API 602/ASME B16.34 Forged Globe Valve – High-Pressure Precision & Durability
Key Structural Features
✅ Full Forged Construction (ASTM A105/A182 F22/F316L):
API 602/ASME B16.34 Compliant: Robust carbon/alloy steel body for Class 1500~4500 steam, oil, and gas systems (up to +593°C).
Port Options: Full port (minimal pressure drop) or standard port (flow control).
Flow Patterns: T-pattern (straight flow) or Y-pattern (low turbulence).
✅ Zero-Leakage Sealing:
Integral Weld-Overlay Seat: Metal-to-metal contact ensures ISO 5208 Class VI bubble-tight shutoff.
Swivel Disc Design: Forged steel disc with tapered/plug seating for precise alignment.
✅ Durable Bonnet Configurations:
Bolted Bonnet: Spiral wound gasket (ASME B16.20) for controlled compression.
Threaded & Seal-Welded Bonnet: Eliminates gasket replacement in high-pressure systems.
✅ Self-Aligning Stem Seals:
Integral Backseat: Stem and bonnet backseat prevent blowout under extreme pressure.
Two-Piece Gland Flange: Uneven tightening resistance, parallel alignment for zero stem wear.
✅ Low-Maintenance Design:
Removable Gland Bolts: Stainless steel stud/eyebolt assembly for easy servicing.
Corrosion-Resistant Yoke Sleeve: Forged stainless steel with high wear resistance.
Open-Spoke Handwheel: Forged carbon steel for high torque and ergonomic operation.
