Product Overview:

Globe valve, also known as shut-off valve, belongs to the forced sealing type valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the frictional force between the valve stem and the packing, as well as the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open it, so the diameter of the valve stem should be larger, otherwise the valve stem bending fault may occur. There are three types of connections: flange connection, threaded connection, and welded connection.

Titanium is a highly chemically active metal. However, it exhibits particularly excellent corrosion resistance to many corrosive media. The reason is that titanium has a good affinity for oxygen, which easily reacts with oxygen to form a strong and dense pure oxide film on its surface. In many harsh corrosive media, this oxide film is very stable and difficult to dissolve. Even if it is damaged, as long as there is sufficient oxygen, it can repair itself and quickly regenerate.

Nickel is a hard, ductile, and ferromagnetic metal that is highly polished and corrosion-resistant.

The working principle of the hose valve (clamp valve) is to squeeze the internal hose through manual, electric, pneumatic, or hydraulic driving methods to achieve the function of switching and adjusting. Its characteristic advantage is that the fully permeable elastic hose has no gaps or dead corners, avoiding turbulence and wear inside the hose; When fully closed, it ensures bidirectional zero leakage closure, and the rubber hose and pipeline system are self-contained. Each opening and closing operation can be self-cleaning without blockage or dirt production. The production process of rubber hoses is divided into two types: compression molding and pure handmade. The materials used include natural rubber (black rubber), LAD special rubber (LNT), EPDM, nitrile rubber, etc. Rubber formula hoses with different properties can be customized for different working conditions, including non-standard, reduced diameter, variable diameter, through diameter, and thickened hoses.
