ANSI High-Pressure Globe Valve
ANSI High-Pressure Globe Valve
Product Overview
The ANSI High-Pressure Globe Valve is a robust flow control and isolation valve designed in accordance with ANSI and ASME standards for high-pressure service conditions. With a linear motion disc and streamlined flow path, this valve provides accurate throttling capability and reliable shut-off performance. It is widely applied in systems where precise flow regulation, pressure control, and operational safety are critical.
Design & Construction
The globe valve adopts a pressure-seal or bolted bonnet structure to ensure tight body-to-bonnet sealing under elevated pressure and temperature. The disc moves perpendicular to the seat, allowing fine adjustment of flow rate while minimizing vibration and seat wear.
Key design features include:
Linear motion disc for precise flow control
Pressure-seal bonnet or bolted bonnet design
Hardened seating surfaces for extended service life
Anti-blowout stem and backseat design
Optional fire-safe construction
