1. Product Overview
A globe valve is a linear-motion valve designed for precise flow regulation, shutoff, or throttling in pipelines. Its disc moves perpendicularly to the seat, ensuring reliable sealing and control. Widely used in steam, water, oil, gas, and corrosive media systems.
2. Key Design Features
- Structure: Spherical body with a baffle separating two halves, vertical disc movement.
- Sealing: Metal-to-metal or soft-seated (PTFE/graphite) for zero leakage.
- Operation: Manual (handwheel), pneumatic, electric, or hydraulic actuation.
- Flow Direction: Typically designed for low-flow resistance with flow-under-the-seat configuration.
