Stainless steel gate valve is a device used to control the direction, pressure and flow of fluid in the fluid system. The material of stainless steel gate valve is an alloy composed of iron, chromium, carbon and many different elements. Iron is the main component element, and chromium is the main alloying element. Generally speaking, the chromium content must account for at least 11% to be called ...

Working principle of globe valves Assuming there is a water supply pipeline with a cover, water is injected from the bottom of the pipeline and discharged towards the direction of the pipe mouth, and the cover of the outlet pipe mouth is equivalent to the closing part of the globe valve. If you lift the pipe cover up with your hand, the water will be discharged outward. If you cover the pipe cover...

(1) Selection principle of valves for water supply pipelines 1. When the diameter of the pipeline is less than 50mm, a globe valve should be used; When the pipeline diameter is greater than 50mm, gate or butterfly valves should be used; 2. When it is necessary to adjust the flow and water pressure, regulating valves and globe valves should be used; 3. For parts with low water flow resistance (such...
