The Stainless Steel Gate Valve Class 800 with hard faced seats is a heavy-duty forged stainless steel isolation valve designed for high-pressure small-bore industrial and process applications. Manufactured from ASTM A182 F316L stainless steel, it provides excellent corrosion resistance and dependable performance in demanding services.
Gate valves are generally used for on/off isolation service, where the valve is operated in either the fully open or fully closed position. When fully open, the gate design provides a low-restriction flow path, making it suitable for applications where minimal pressure drop is preferred.
This valve features hard faced seats for improved wear resistance, a stainless steel stem, and graphite gaskets and packing for high-integrity sealing. It is designed and manufactured in accordance with API 602 and is available with NPT threaded ends to ASME B1.20.1 or socket weld ends to ASME B16.11.
A gate valve is designed for full shut-off and isolation rather than flow regulation. When fully open, the gate is completely out of the flow path, providing minimal pressure drop and unobstructed flow, making it ideal for high-pressure pipelines and critical process systems.
Hard-faced seats provide exceptional wear and abrasion resistance, ensuring a tight seal even in high-pressure, high-temperature, and aggressive service conditions. This extends valve life and reduces maintenance in demanding industrial applications.
ASTM A182 F316L stainless steel offers excellent corrosion resistance, strength, and durability. It withstands pitting, chemical attack, and high temperatures, making it ideal for oil & gas, petrochemical, power generation, and other industrial systems.
This valve comes with NPT threaded ends to ASME B1.20.1 and socket weld ends to ASME B16.11. These options provide flexible installation in compact or welded pipeline systems, ensuring secure, leak-tight connections in a variety of configurations.
The combination of hard-faced seats, stainless steel stem, and graphite gaskets ensures tight sealing and smooth operation under extreme pressures and temperatures. This allows reliable, long-term performance in critical industrial and utility systems.
