What are isolation valves & how do they work?
Unlike check valves (which prevent fluid backflow), the core function of isolation valves is to physically block the flow path to achieve segmented isolation of the system, thereby ensuring safety and controllability during equipment maintenance, overhaul or emergency shutdown.
What is an isolation gate valve?
Isolation Gate Valve: specifically refers to the isolation valve type with a gate structure. ISO : International standard for the classification of valve leakage rates (e.g. Class VI is a high sealing level). API 600: American Petroleum Institute design and manufacturing standard for steel gate valves.
How to choose a safe isolation valve?
Summary: The selection of isolation valves must be based on safe isolation, and the media, pressure, operating logic and cost must be considered comprehensively, and industry standards (such as API 600, ISO ) must be strictly followed.
What is the difference between stop valve and ball valve?
The stop valve is installed according to the flow direction (the valve seat side is the inlet), and the ball valve and gate valve can be installed in both directions. The valve stem of a horizontal pipeline is vertically upward, and the valve stem of a vertical pipeline is inclined ≤45° (for easy operation). Common Mistakes :
