Mud pump valve assembly is the key component of the hydraulic end of the mud pump. The valve assembly consists of valve body, valve rubber, valve nut, guide frame, gland, clamp spring, steel ball, etc. (i.e. valve assembly with valve seat removed).
Four-rib valve body is made of high-quality forged steel with high strength and hardness. The rubber is fixed on the valve body by the valve nut. The valve seat has high strength and impact resistance, and is suitable for high-pressure jet drilling. Compared with four ribs, the three-rib valve body seat has larger displacement, and can provide directly assembled valve body and valve rubber with long service life. The rubber is made of polyurethane material, and the effective service time is more than 300 hours, which greatly improves the overall service life of the valve assembly.
