API600 150LB RF Cast Steel WCB Wedged Gate Valve: Industrial-Grade Fluid Control Excellence
Designed to meet the rigorous demands of heavy-duty industrial applications, the API600 150LB RF Cast Steel WCB Wedged Gate Valve stands as a benchmark for reliability, durability, and performance. Compliant with API 600 (BS EN 12516-1) standards—globally recognized for gate valve design and manufacturing—it ensures consistent operation in critical fluid handling systems.
Key Features & Technical Specifications:
1. Full API 600 Compliance: This valve is not just "designed to" but is fully manufactured to meet API 600 standards. This guarantees specific requirements for materials, design, testing, and documentation, ensuring unparalleled quality and safety for severe service applications.
2. Superior Body Material (ASTM A216 WCB): The valve body and bonnet are constructed from ASTM A216 Grade WCB Carbon Steel. This material offers excellent mechanical strength, pressure integrity, and resistance to erosion and high temperatures (up to ~800°F / 427°C), making it ideal for a wide range of hydrocarbons, steam, water, and other non-corrosive services.
3. Pressure Class & End Connection:
Pressure Rating: 150LB (Class 150): Suitable for a broad range of medium-pressure applications.
End Connection: Raised Face (RF) Flanges: Standard ASME B16.5 RF flanges ensure a secure, leak-proof connection to your piping system. The serrated finish on the Raised Face provides an excellent seal with standard gaskets.
4. Advanced Wedge Design (Flexible Wedge): The heart of this valve's sealing performance is its flexible wedge design. The wedge features a precision-machined groove around its perimeter, allowing it to flex slightly under system pressure. This self-adjusting capability compensates for thermal expansion, pipeline stress, and seat wear, guaranteeing a bubble-tight seal throughout its operational life and preventing seat binding.
5. Bolted Bonnet Construction: Provides a strong, pressure-boundary seal between the body and bonnet. This design allows for easier field maintenance, inspection, and internal part replacement compared to pressure-seal bonnets used in higher-class valves.
6. Stem & Operational Efficiency:
Rising Stem (OS&Y - Outside Screw & Yoke): The stem rises as the valve is opened, providing a clear visual indicator of the valve position (open or closed).
The threads are located outside the flow path, protecting them from corrosion and erosion, ensuring smooth, low-torque operation over the valve's lifetime.
7. Rigorous Testing: Every valve undergoes 100% individual testing, including:
Shell Test: Hydrostatic testing of the pressure-containing body.
Seat Test: Hydrostatic testing for both upstream and downstream sealing to ensure zero leakage.
Additional tests like nitrogen testing or fire testing are performed as required.
