ANSI API Globe Valve
ANSI API globe valves are linear motion control valves designed for precise flow regulation and reliable shut-off in industrial piping systems. Manufactured in accordance with ANSI and API standards, they are suitable for high-pressure, high-temperature, and critical service applications.
Overview
ANSI API globe valves are widely used for throttling and flow control applications. Their design allows accurate regulation of fluid flow and provides reliable shut-off, making them ideal for services where frequent operation and control are required.
Design & Operation
- Linear motion valve with a disc moving perpendicular to the seat
- Requires lower operating torque compared to gate valves
- BY-pass valves can be installed to reduce differential pressure during opening and closing
- Provides good sealing performance and controlled flow characteristics
Materials & Construction
- Available in carbon steel and stainless steel constructions
- Seat can be hard-faced with Stellite to extend service life and reduce wear
- Robust body design suitable for demanding industrial conditions
Pressure & Temperature Ratings
- Pressure classes: Class 150 to Class 2500 (LBS)
- Operating temperature range: approximately -25 °C to +425 °C
End Connections
- Flanged connections according to ANSI or DIN standards
- Threaded connections
- Welded end connections
Types of ANSI API Globe Valves
- Straight pattern globe valves
- Y-pattern globe valves
- Angle (90°) globe valves
- Stop check globe valves
- Globe control valves
- Positive and adjustable chokes to API 6A
- Extended bonnet globe valves for cryogenic services
