SUMMARY

In steam line connections, the common practice is to use globe valves for throttling applications due to their superior flow control capabilities. Gate valves are typically specified when the valve is normally open and only closed for maintenance, as they are more cost-effective. Throttling with a gate valve leads to rapid wear and leakage, making globe valves the preferred choice for controlling flow in steam lines.

PREREQUISITES
  • Understanding of valve types: globe valves and gate valves
  • Knowledge of steam line applications and maintenance practices
  • Familiarity with flow control mechanisms in piping systems
  • Basic principles of valve operation and wear characteristics
NEXT STEPS
  • Research the specifications and applications of globe valves in steam systems
  • Learn about the maintenance practices for gate valves and their limitations
  • Explore the impact of valve selection on steam line efficiency
  • Investigate alternative valve types for specific steam line applications
USEFUL FOR

Engineers, maintenance personnel, and professionals involved in steam system design and operation will benefit from this discussion, particularly those focused on valve selection and flow control strategies.

hi guys...can anyone tell me that whether v use only globe valve in steamline connections in common practice?
 
Engineering news on Phys.org
If the valve is normally open, and closed only to isolate the line for maintenance then a gate valve would be specified (lower cost). If the valve is throttled to control flow a globe valve is specified. Throttling a gate valve offers poor flow control and quickly wrecks the discs so the valve will leak by when closed.
