Valve Assembly as the core component of the hydraulic end of the mud pump, its importance is self-evident. It is directly involved in the high-pressure mud circulation process in drilling operations and is the key to ensuring efficient and stable operation of mud pumps. The valve assembly consists of valve body, valve rubber, valve nut, guide frame, gland, spring, steel ball and other precision components (not including the seat), which work together to withstand high frequency impact and wear.

The main role of the Valve Assembly is to control the flow of mud, through its precise opening and closing action, to achieve effective mud circulation and pressure regulation during drilling. Its working frequency is high and the impact is large, so its quality directly determines the service life of the liquid cylinder and even the entire mud pump. As one of the main parts in the hydraulic end system of drilling mud pump, the valve assembly is one of the most consumable parts in drilling work, and its stability and durability are crucial to ensure the safety and efficiency of drilling operations.

The valve body and valve seat are made of high quality bonded steel 20CrMnTi material, after carburizing and quenching treatment, the surface hardness is as high as HRC60 or more, and the cone is precision grinding to ensure high roughness requirements and accurate geometry, thus improving the sealing performance and wear resistance of the valve assembly. At the same time, the valve body is made of high-quality forged steel with high strength and hardness, which can withstand the extreme conditions of high-pressure jet drilling.

In summary, Valve Assembly, with its excellent performance and high durability, plays an irreplaceable role in the hydraulic end system of drilling mud pump, and is an important component to ensure the smooth progress of drilling operations.
