Product Description
API 600 Cast Steel Wedge Gate Valve
Our API 600 Series Cast Steel Gate Valves are designed for superior flow control in heavy-duty industrial piping systems. Available in standard ASTM A216 WCB and enhanced WCB+STL (Stellite 6 Overlay) configurations, these valves offer high-performance sealing and durability across Class 150 to Class 200 pressure ratings. The Outside Screw and Yoke (OS&Y) design ensures the stem threads remain external to the media, preventing corrosion and extending service life.
Configuration Options: WCB vs. WCB+STL
To meet diverse operational demands, we provide two specialized trim and seating configurations:
| Feature | Standard WCB Configuration | Premium WCB + STL Configuration |
|---|---|---|
| Body/Bonnet Material | ASTM A216 WCB (Cast Carbon Steel) | ASTM A216 WCB (Cast Carbon Steel) |
| Seating Surface | Integrated Carbon Steel or 13Cr | Stellite No. 6 (Cobalt-Based Alloy) |
| Hardness & Durability | Standard industrial wear resistance | Superior hardness (HRC 37-45); Erosion resistant |
| Temperature Range | -29°C to 425°C | Optimized for high-temp & abrasive media |
| Best For | General oil, gas, and water utility | High-cycle apps, steam, and corrosive fluids |
Technical Parameters & Compliance
- Design & Manufacture: Fully compliant with API 600 and ASME B16.34
- Pressure Rating: Specifically engineered for Class 150 and Class 200 (PN20 - PN32) service
- Face-to-Face Dimensions: According to ASME B16.10
- Flange End Dimensions: According to ASME B16.5
- Inspection & Testing: 100% tested per API 598 (Shell, Backseat, and Closure leakage tests)
- Wall Thickness: Heavy-duty API 600 wall thickness for extra safety margin and corrosion allowance
Advanced Engineering Features
- Flexible Wedge Design: The wedge is precision-ground to a slight taper, allowing it to adapt to seat deformations caused by pipe stress or thermal expansion, ensuring a bubble-tight shutoff
- Stellite-Faced Seats (STL Model): By applying a Stellite #6 overlay on the seat rings and wedge faces, we provide a metal-to-metal seal that resists "galling" and maintains integrity under high-velocity flow
- Bolted Bonnet (BB): Features a high-tensile strength bolt-and-nut assembly with a controlled-compression gasket for zero-leakage at the bonnet joint
- Integral Backseat: Allows for the replacement of stem packing while the valve is in the fully open position under pressure
Application & Industries
- Oil & Gas: Upstream production and downstream refining
- Power Plants: High-pressure steam and cooling water cycles
- Chemical Processing: Handling non-corrosive and mildly abrasive hydrocarbons
- Infrastructure: Municipal water treatment and high-pressure fire protection systems
