Installed in the hydraulic end valve box of the mud pump, it controls the closure of the inlet and outlet valves, consisting of a valve body and a valve seat. The main materials are made of alloy steel (20CrMnTi, 20CrNiMo) that is higher than the standards of the petroleum industry, and are forged as a whole. The heat treatment method used ensures that the product has high strength and toughness, with a working surface hardness of HRC58 or above, and is processed and manufactured according to strict process regulations to ensure high smoothness and accurate dimensions.

    Valve rubber, also known as valve rubber, is the main component in the hydraulic end system of drilling mud pumps. It is a critical part of the valve body's service life and one of the most commonly used vulnerable parts in mud pumps. Valve rubber is a vulcanized rubber product. The material of ordinary valve rubber is nitrile rubber, but polyurethane rubber can also be used to increase the working temperature range of the rubber. Our company has developed valve rubber with a formula, which can effectively improve wear resistance, extend service life, and improve the efficiency of mud pumps compared to ordinary valve rubber.
