Characteristics of valve manufacturing process..
Valves are important opening and closing and regulating components of pressure pipelines, and their operating conditions vary greatly. However, the test and inspection conditions for valve manufacturing can usually only be carried out under conditions close to normal temperature, using gas or water as the medium for testing.

Types, structural features and differences of wedge gate valves..
The gate of the wedge gate valve is wedge-shaped, which can be seen from the force analysis of the wedge gate. The downward thrust of the valve stem decomposes the positive pressure on the valve seat sealing surface, which has an auxiliary sealing effect on low-pressure media. It avoids the situation where the sealing effect of low-pressure media is poor in the flat gate valve. At high pressure, the medium pressure is relied on to push the gate to press on the outlet valve seat to maintain the seal.

Differences between castings and forgings..
Castings: Various parts with complex shapes can be manufactured, including curves, thin walls, and uneven structures, and their shapes and sizes are mainly determined by the mold.Forgings: Although complex shapes can also be manufactured, their shape and size flexibility is slightly inferior to castings. Forgings focus more on improving the internal organization and properties of metals through the forging process.

Valve with pressure maintenance precautions..
Valve maintenance under pressure is a simple, dangerous and low technical task. In addition to being serious, careful and calm, the valve pressure maintenance should also have a strict scientific attitude. In particular, the sealing work of explosive, highly toxic, high temperature, high pressure, radioactive and other media should be strictly carried out in accordance with the scheduled plan and relevant safety regulations

Classification and related standards for globe valves..
The globe valve refers to the valve that the closing part (valve disc) moves along the axis of the seat, and the globe valve is mainly used for cutting off the pipeline. Because the seal is reliable, the opening and closing stroke is short, the pressure on the valve stem directly presses the sealing surface, and there is almost no friction on the sealing surface when sealing, so the vacuum valve is often used as a stop valve. Generally, there is only one sealing pair, good manufacturing process, and the seat and valve disc are also easy to repair and replace. Due to the limitation of the shape

Gate valve design standard..
Gate valves are available in a variety of materials and pressure grades, ranging in size from the palm-sized NPS ½ inch to the truck-sized NPS 144 inch. Gate valves are constructed of castings, forgings or weld-made components, in which the casting design dominates.
