CNLD valve is a robust flange-end gate valve designed and manufactured in strict compliance with the API 600 standard for “Steel Gate Valves.” It is engineered for reliable, long-term service in demanding industrial applications where shut-off integrity is critical.
Key Design & Construction Features:
Design Standard: API 600
Valve Type: Gate Valve (Rising Stem, Outside Screw & Yoke – OS&Y)
End Connection: Flanged (RF or RTJ as per order specification). Dimensions conform to ASME B16.5 or relevant standards.
Pressure Class: Standard offerings include Class 150, 300, 600, and higher as required.
Trim Material – Critical Component: The valve features a C95800 (Aluminum Bronze) disc.
C95800 Alloy is a high-strength nickel-aluminum bronze known for its excellent corrosion resistance, particularly in seawater, brackish water, and various chemical services.
It offers superior galling resistance and good bearing properties, making it an ideal choice for the valve’s sealing component (the disc) which is in repeated contact with the seat surfaces.
This trim is especially recommended for handling corrosive fluids, including saltwater, hydrocarbons with traces of H2S and CO2, and other challenging media.
