Features of Globe Valves

The globe valve holds a significant position in industrial piping systems. Its diverse characteristics enable it to adapt to numerous complex working conditions and application requirements. Deeply understanding the various features of the globe valve is crucial for optimizing the design of piping systems, ensuring precise fluid control, and guaranteeing the long-term stable operation of the systems

1. Structure and Design
Globe valves have a globular body. The disc, attached to a stem, moves relative to the seat. Inlet & outlet ports at different levels enable precise flow control.
The bonnet houses the stem & packing gland. Different bonnet designs like bolted, screwed, or welded are available for various needs.
2. Flow Control Capability
The linear motion of the disc offers fine-tuned flow rate adjustments. Ideal for precise control in chemical dosing & heating/cooling systems.
Can handle a wide range of flow rates, though less efficient in high-flow vs some valves, but good at low-flow control.
3. Sealing Performance
The disc-seat interaction seals the valve. Materials like metal or soft ones affect sealing. Soft-seated valves are good for leak-free needs.
Regular maintenance of the packing gland & inspection/replacement of disc/seat are needed for long-term sealing.
4. Pressure Handling Capacity
Globe valves can handle various pressures. High-pressure ones have thicker walls & stronger materials.
Suitable for high-pressure industries like oil and gas due to reliable pressure handling.
5. Resistance to Wear and Corrosion
Corrosion-resistant alloys or coated materials are used for corrosive fluids.
Hard materials or surface treatments on disc/seat increase durability against wear.
In conclusion, globe valves' features make them reliable for many piping systems & industrial applications.
