6" Class 900 API 600 LCB Gate Valve, Butt Weld OS&Y for Low-Temperature Service

This 6-inch Class 900 LCB gate valve (ASTM A352 LCB body) is API 600 compliant, designed for high-pressure, low-temperature industrial applications. It features a bolted bonnet, OS&Y handwheel operation, and butt-weld ends for secure, leak-tight isolation in oil & gas, petrochemical, and cryogenic pipelines.

• Gate Valve
• API Gate Valve
• LCB Gate Valve

This heavy-duty gate valve is designed and manufactured to meet API 600 and ASME B16.34 standards, engineered for reliable isolation in high-pressure, low-temperature industrial applications.

Key Specifications:

• Design Standard: API 600 / ASME B16.34
• Size: 6" (NPS 6)
• Pressure Rating: 900 LB (Class 900)
• Body Material: ASTM A352 LCB (Low-Temperature Carbon Steel)
• End Connection: Butt-Weld (BW)
• Bonnet Type: Bolted Bonnet
• Operation: Handwheel Operated (Outside Screw & Yoke / OS&Y)
• Testing Standard: API 598

Features & Benefits:

1. Low-Temperature Compatibility: The LCB cast steel body provides excellent toughness at sub-zero temperatures, making it ideal for cryogenic and low-temperature service in oil & gas, petrochemical, and LNG facilities.
2. Robust Construction: The bolted bonnet design ensures a secure, pressure-tight seal while allowing for easy maintenance of internal components.
3. Visual Position Indication: The OS&Y (Outside Screw and Yoke) design exposes the rising stem, allowing operators to visually confirm the valve’s open or closed status at a glance.
4. Full Bore Flow: The full-port design minimizes pressure drop and turbulence, enabling efficient pigging operations and unobstructed flow.
5. Durable Sealing: Precision-machined gate and seat surfaces ensure bi-directional bubble-tight shutoff, preventing media leakage in demanding process conditions.

Applications:Ideal for use in pipelines carrying natural gas, crude oil, liquefied gases, and other low-temperature fluids in refineries, chemical plants, power stations, and offshore platforms.
