Its versatile size range (1/2''-12'') and dual pressure ratings (150LB/300LB) ensure compatibility with diverse pipeline systems, while its robust component materials guarantee long-term operation even under harsh conditions. Whether you need to control high-pressure fluids or maintain leak-tight performance, this globe valve is a cost-effective solution that minimizes downtime and enhances system safety.
Core Advantages & Technical Highlights
Multi-Standard Compliance: Adheres to API 6D/600/603 (design), ASME B16.10 (face-to-face), ASME B16.5 (flange), and API 598 (testing) standards, ensuring seamless integration with global industrial systems and meeting strict quality benchmarks.
Diverse Material Options: Body available in ASTM A216 WCB (carbon steel), ASTM A351 CF8 (304 stainless steel), and ASTM A351 CF8M (316 stainless steel); stem options include 2Cr13, SS304, SS316, and carbon steel—catering to different fluid types (e.g., corrosive chemicals, high-temperature oils).
Leak-Tight Sealing: Features seats made of 13Cr, CF8, or CF8M paired with graphite gaskets, providing excellent sealing performance to prevent fluid leakage and ensure system efficiency.
Precise Flow Control: Globe valve design enables linear flow regulation, making it easy to adjust flow rates with accuracy—critical for processes that require stable fluid pressure or flow volume.
Durable Operation: Disc made of ASTM A216 WCB and hand wheel of ASTM A47 offer high impact resistance and wear resistance, reducing maintenance frequency and extending the valve’s service life.

FAQ
1. What’s the difference between API 6D, API 600, and API 603 design standards for this valve?
API 6D focuses on pipeline valves (e.g., for oil/gas transmission), API 600 covers bolted bonnet steel globe valves for general industrial use, and API 603 specifies small-bore carbon steel and alloy steel globe valves. All three standards ensure quality, but you can select based on your industry (e.g., API 6D for long-distance pipelines, API 600 for chemical plants).
2. Which body material should I choose for corrosive fluid applications?
For corrosive fluids (e.g., acids, saltwater), select ASTM A351 CF8 (SS304) or ASTM A351 CF8M (SS316)—both are stainless steel materials with strong corrosion resistance. ASTM A216 WCB (carbon steel) is better for non-corrosive fluids like water or oil.
3. Can this valve be used for high-temperature applications?
Yes. ASTM A216 WCB (body) can withstand up to 427°C (800°F), while CF8/CF8M can handle up to 816°C (1500°F). For temperatures above 427°C, we recommend pairing with SS304/SS316 stems to ensure thermal stability.
4. Is the graphite gasket replaceable, and how often should it be changed?
Yes, the graphite gasket is replaceable. Replacement frequency depends on usage: for regular industrial use (8-12 hours/day), replace every 1-2 years; for high-pressure/high-temperature applications, inspect quarterly and replace if signs of wear (e.g., leaks) appear.
5. Does this valve comply with ASME B16.5 flanges of all pressure classes?
It complies with ASME B16.5 flanges matching its pressure ratings: 150LB valves work with ASME B16.5 150LB flanges, and 300LB valves match ASME B16.5 300LB flanges. Ensure flange pressure class aligns with the valve’s rating for safe installation.
6. What is API 598 testing, and why is it important?
API 598 includes hydrostatic (water pressure) and pneumatic (air/gas pressure) tests to check for leaks, plus visual and dimensional inspections. It ensures the valve meets leak-tight requirements and structural integrity, preventing safety hazards and operational losses.
Can this globe valve be automated (e.g., with an electric or pneumatic actuator)?
Yes. The valve’s hand wheel is removable, and we offer customization for electric, pneumatic, or hydraulic actuators. Contact our team with your actuator type and control requirements to get a modified product.
8. What is the maximum flow rate this valve can handle?
Flow rate depends on size and pressure: a 12'' 300LB valve can handle up to ~500 GPM (gallons per minute) for water, while a 1/2'' 150LB valve handles ~5 GPM. For precise flow rate calculations, provide our team with fluid type, temperature, and pressure, and we’ll generate a detailed report.
