API Globe Valve
API globe valve is a forced sealing valve, usually used as an isolation valve for the medium, and its opening and closing parts (valve discs) move up and down along the center line of the valve seat channel. Since the flow area of the valve seat is proportional to the opening and closing stroke of the opening and closing parts, our valves can properly adjust the flow for your application, but when you have special requirements for flow characteristics, you should carefully consider whether the globe valve itself can be used as a control valve.
If you have any questions, please contact our sales manager immediately, because we are a professional globe valve manufacturer and exporter.
Description
American globe valves mainly include API, ASME and ASTM standards.
ASTM is a material standard, not a standard for the valve itself.
TOT globe valves designed, manufactured, produced and tested completely in accordance with API standards are called API globe valves.

Product Advantages
– Small fluid resistance, its resistance coefficient is equal to that of the pipe section of the same length.
– Simple structure, small size and light weight.
– Tight and reliable, the sealing surface material of the globe valve is currently widely plastic, with good sealing performance, and has been widely used in vacuum systems.
– Easy to operate, quick opening and closing, from full open to full closed, only need to rotate 90°, which is convenient for remote control.
– Easy maintenance and simple structure, the sealing ring is generally movable, and it is convenient to disassemble and replace.
– When fully open or fully closed, the sealing surface of the valve body and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when passing through.
– Wide range of applications, the diameter ranges from a few millimeters to several meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, the inlet and outlet should all present spherical surfaces, thereby cutting off the flow.
– Widely used in petrochemical, electric power, metallurgy, medicine, real estate, municipal engineering and other industries.
API Globe Valve Standard
The API Globe Valve produced by TOT Valve is manufactured in full accordance with API standards, including design, length and flange connection dimensions. We strictly inspect and test them according to the pressure and temperature under ANSI B16.34 standards to ensure that you get almost the same service life in different application environments.
| Design Spec | Face to Face | Flange Dimension | Welding Connection | Pressure-Temp | Inspection & Test |
| ANSIB16.34 BS1873 | ANSIB16.10 | ANSI B16.5 | ANSIB16.25 | ANSIB16.34 | API598 |
API Globe Valve Pressure Test
TOT applies pressure to the Globe Valve in one direction according to the API standard, and the pressure is applied below the valve disc for pressure testing. The following is our summary of the pressure test results for your reference to ensure that you avoid unnecessary losses due to excessive pressure during your application.
