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 ...

The opening and closing part of the bellows seal globe valve is a plug-shaped disc, the sealing surface is flat or conical, and the disc moves linearly along the center line of the fluid. The movement form of the valve stem includes a lifting rod type and a lifting rotating rod type. The bellows seal globe valve is only suitable for full opening and full closing, and adjustment and throttling are ...

The working principle of the forged steel ball valve is to make the valve unblocked or blocked by rotating the valve stem. The ball valve is easy to switch, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easy to be eroded by the medium, and...

Soft seal gate valve is a common industrial valve. The opening and closing part of soft seal gate valve is a wedge. The direction of movement of the wedge is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. When manufacturing soft seal gate valves in batch, the following performance tests should be carried o...

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...

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 ...

The flat gate valve is characterized by small flow resistance. Since the wedge slides on two valve seat surfaces, the flat gate valve is also suitable for fluids with suspended particles. Double block discharge function: When the valve is opened or closed, the medium from upstream and downstream will not leak from the valve cavity, which is convenient for the cavity discharge and leak detection. F...
