Products Details

API Flanged Globe Valve is a valve designed and manufactured according to the American Petroleum Institute (API) standard, which is widely used in petroleum, chemical, pharmaceutical, fertilizer, power and other industries to control the flow of fluids. Here are some details about American standard flanged globe valves:

Design and manufacturing standards: American standard flanged globe valves are usually designed and manufactured in accordance with API 600, API 603 and ASME B16.34 standards to ensure their reasonable structure, reliable sealing and excellent performance.

Material: The body material includes WCB, CF8, CF8M, etc., and the disc material is A105, F304, F316, etc., to adapt to different working conditions and media.

Connection mode: This valve adopts flange connection mode, and the flange size complies with ANSI B16.5 standard.

Nominal diameter and pressure: The nominal diameter of American standard flanged globe valves ranges from 2 inches to 20 inches, and nominal pressure classes include 150LB, 300LB, 600LB, etc.

Applicable media and temperature: suitable for water, oil, steam, acid and alkali corrosive media and other media, working temperature range from -40℃ to 425℃.

Sealing performance: the sealing surface of the valve disc and seat is made of iron-based alloy surfacing or Stelli cobalt-based cemented carbide surfacing, with wear resistance, high temperature resistance, corrosion resistance and abrasion resistance, thus extending the service life.

Valve stem design: The valve stem has been tempered and surface nitriding treatment, with good corrosion resistance and abrasion resistance.

Drive mode: American standard flanged globe valves are usually equipped with a manual drive mode, but other drives can be configured according to demand.

Structural features: The disc is plug shaped, the sealing surface can be flat or conical, and it moves in a straight line along the center line of the seat, suitable for cutting off or regulating the flow.

Fluid resistance: Due to its straight-through flow shape, the fluid resistance is small and equal to the length of the pipe.

Operation convenience: Easy to operate, from full open to full close only need to rotate 90°, easy to remote control.

Maintainability: simple structure, sealing ring can be disassembled and replaced, easy maintenance.

Sealing surface protection: When fully open or fully closed, the sealing surface is isolated from the medium to reduce erosion.

Scope of application: Suitable for small caliber to large caliber, from low pressure to high pressure applications.
