API 600 STANDARD · CLASS 150–2500 · NPS 1"–40"
The API 600 Flanged Gate Valve is a heavy-duty, full-bore
isolation valve manufactured to API 600 standards for critical
oil, gas, and refinery pipeline applications. Pressure-rated
from Class 150 to Class 2500 per ASME B16.34, it delivers
zero-leakage shutoff performance under extreme pressure
and temperature conditions up to 538°C, making it the
industry standard choice for upstream, midstream, and
downstream petroleum pipeline systems worldwide.

For Class 900 and above, the pressure seal bonnet design isstandard, where system pressure energizes the bonnetgasket seal, providing superior leak-tightness under highpressure cyclic conditions. Renewable Stellite-overlaid seatsare accessible without removing the valve from line,significantly reducing maintenance costs and downtime incritical pipeline service

Những câu hỏi thường xuyên
What is an API 600 flanged gate valve, and where is it used?
API 600 is the American Petroleum Institute standard for bolted-bonnet steel gate valves used in petroleum, natural gas, and petrochemical pipelines. Gate valves are designed for full-bore isolation — they provide unrestricted flow when fully open and tight shut-off when closed, with minimal pressure drop across the valve. They are not suitable for throttling. API 600 gate valves are the industry standard for refineries, upstream oil and gas, LNG terminals, power plants, and offshore platforms where reliable full-bore isolation under high pressure and temperature is required.
How do I select the right pressure class for my pipeline — Class 150 through Class 2500?
Pressure class selection is based on your pipeline's maximum allowable operating pressure (MAOP) and temperature. As a general guide: Class 150 suits low-pressure systems up to ~19.6 bar; Class 300 covers medium-pressure lines up to ~51 bar; Class 600 handles high-pressure service up to ~102 bar; Class 900 up to ~153 bar; Class 1500 up to ~255 bar; and Class 2500 covers extreme-pressure service up to ~425 bar at ambient temperature. Always verify against the ASME B16.34 pressure-temperature rating tables for your exact body material and operating temperature, as ratings decrease as temperature rises. Bautu's engineers can assist with class selection based on your process datasheet.
What sizes and lead times are available, and what custom options does Bautu offer?
Bautu manufactures API 600 gate valves from NPS 1" to NPS 40" across all pressure classes. Standard sizes in Class 150 and Class 300 are delivered in 5–7 weeks; large bore sizes (NPS 24" and above) or higher pressure classes (Class 900–2500) typically require 8–12 weeks. Custom configurations include WCB, LCB, WC6, WC9, and CF8M body materials, OS&Y (outside screw and yoke) or non-rising stem designs, gear operator or electric actuator packages, and full third-party inspection (API monogram, SGS, BV, TÜV).
