Globe Valve is widely used in various industrial and civil pipeline systems. It has excellent cut-off performance, good adjustment ability and tight sealing. It is very suitable for systems with strict control requirements on flow, pressure and temperature.
1. The core function of the stop valve
1. Cut off the flow of the medium (open/close control)
2. Regulate the flow of fluid (can be used as a regulating valve)
3. Ensure the safe operation of the system (prevent backflow or leakage through tight closing performance)
2: Key points for installation and use
1. The installation direction must be correct: There is usually a flow arrow on the valve body, and it should be installed in the direction of the arrow (the medium should enter from below the valve seat)
2. Appropriate opening method: The stop valve is suitable for full opening or full closing, and can also be used for adjustment, but it is not suitable for long-term operation in a slightly open state
3. It is recommended to install it on a horizontal pipeline with the valve stem vertically upward for easy maintenance
4. Check the packing seal regularly to prevent valve stem leakage
5. Pay attention to the influence of thermal expansion under high temperature conditions, and a bellows sealing structure can be used
3: Advantages of the stop valve in the pipeline system
● Large closing torque and reliable sealing
● Applicable to high temperature and high pressure environments
● The adjustment function is better than that of gate valves or ball valves
● Compact structure and easy installation
● Excellent performance in occasions where frequent opening and closing are required
