The opening and closing part of the gate valve is the wedge, and the movement direction of the wedge is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and is not suitable for adjustment and throttling. Most gate valves are forcibly sealed, that is, when the valve is closed, the wedge must be forced against the valve seat by external force to ...

Fully welded ball valves are mainly used to cut off, distribute and change the flow direction in the pipeline. The valve relies on the pressure in the pipeline and the spring preload to ensure that the valve is completely sealed. Functions of Fully Welded Ball Valve: 1. The valve is composed of fully welded valve body and carbon-reinforced flon gasket, which can operate for a long life under the c...

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 ...
