ASTM A890 6A globe valve is a type of valve constructed from super duplex stainless steel (ASTM A890 6A) designed for flow regulation in pipelines, offering excellent corrosion resistance and strength. These valves are typically used for applications requiring precise flow control and are suitable for various industries due to the material’s durability and resistance to harsh environments.
-
Material:ASTM A890 6A, a super duplex stainless steel, provides superior corrosion resistance and strength compared to other materials.
-
Function:Globe valves are designed for both stopping/starting and regulating fluid flow in pipelines.
-
Design:They feature a movable plug or disc element that moves linearly against a stationary ring seat within a spherical body.
-
Applications:Suitable for a wide range of industries including oil and gas, chemical processing, and other applications where corrosion resistance and reliable flow control are essential.
- The ASTM A890 6A material is also designated as CD3MWCuN or Grade 6A, and is equivalent to the wrought super duplex stainless steel S32760.
- These valves can be found in various sizes, pressure ratings, and end connections, including flanged, welded, or threaded.
- They may be operated manually or with actuators (pneumatic or electric) for automated control.
- Leakage classes for these valves can meet standards like ANSI B16.104, Class IV or Class VI.
- Flow characteristics can be customized as equal percentage or linear, depending on the application requirements.
