Descrizione di prodotto
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
