Product Selection Differences for Hand Operated Hard Seated Globe Pattern Valves

When selecting hand-operated hard-seated globe pattern valves, there are several key differences to consider:

1. Material: Consider the material of the valve body and the seating surface. Hard-seated valves are typically made of metals like stainless steel, bronze, or alloy steel for durability and resistance to wear.

2. Pressure and Temperature Ratings: Check the pressure and temperature ratings of the valves to ensure they meet the requirements of your application. Hard-seated valves are suitable for high-pressure and high-temperature applications.

3. Size and End Connections: Consider the size of the valve required for your system and ensure it has the appropriate end connections (flanged, threaded, etc.) for easy installation.

4. Flow Characteristics: Globe valves offer good throttling capability compared to other valve types. Consider the flow characteristics of the valve and how it will affect your system performance.

5. Actuation Type: Since you are considering hand-operated valves, ensure that the handwheel or lever mechanism is easy to operate and provides precise control over the flow.

6. Sealing Mechanism: Hard-seated globe valves have a metal-to-metal seal between the disc and seat. Ensure the sealing mechanism is designed to provide tight shutoff and long-term reliability.

7. Maintenance Requirements: Consider the maintenance requirements of the valve, including ease of disassembly and replacement of components like the seat and packing.

8. Manufacturer Reputation: Choose valves from reputable manufacturers known for quality products and reliable performance.

Considering these factors will help you select the most suitable hand-operated hard-seated globe pattern valve for your specific application needs.
