1. Key Points for Commissioning Plunger Valves into Operation. When a new plunger valve is put into operation, the nuts on the valve cover should be retightened one by one. This operation must be completed within 1 hour after the valve reaches its operating temperature, and the valve should be in the closed position during…
A plug valve is a common shut-off valve. As a crucial component in industrial applications, it has long been known for their unique structure and versatile uses. The metal seated lift plug valve features dual-directional sealing on both valve seats, making it insensitive to flow direction. During closure, the handwheel and stem apply pressure to the…
Ⅰ.Classification of plug valves. A plug valve opens and closes by rotating a plug around the axis inside the valve body’s central cavity. In pipelines, it is primarily used to cut off, distribute, and change the flow direction of media. An important characteristic of plug valves is their easy adaptation to multi-channel structures, allowing a…
A plug valve is a rotary valve with a closing part or a plunger shaped structure. It realizes opening or closing by rotating 90 degrees to make the passage on the plug communicate with or separate from the passage on the valve body. The shape of its plug can be cylindrical or conical. In a…
