Globe Valve Presentation
Transcript of Globe Valve Presentation
What is a globe valve: is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. When a globe valve is manually operated, the stem is turned by a handwheel.
The body is the main pressure containing structure of the valve and the most but easily identified as it forms the mass of the valve. Bonnet
The bonnet provides a leakproof closure for the valve body. The threaded section of the stem goes through a hole with matching threads in the bonnet
Plug or disc (disk)
The closure member of the valve. Plugs are connected to the stem which is slid or screwed up or down to throttle the flow. Stem
The stem serves as a connector from the actuator to the inside of the valve and transmits this actuation force. Stems are either smooth for actuator controlled valves or threaded for manual valves. Seat ring
The seat ring provides a stable, uniform and replaceable shut off surface. How it Operates??:
*Manually ( Handwheel)
*Actuator If you dont have a clue, what does it mean dont worry! Please
