There are API No.6 and API No.7, which are suitable for F- 1300 and F- 1600 pumps respectively. Generally speaking, mud pumps need six sets of valve assemblies, which are divided into three inlets and three outlets. Some fracturing trucks are equipped with valve assemblies, but they are small in size, commonly known as No.5 in the market. The quality of valve components produced by many manufacturers is uneven. , theirs is 20CrMnTi forging carburizing quenching?
