Product Description

Valves and Seats are a critical component of the mud pump hydraulic end, engineered to withstand high-frequency operation and severe impact loads. Forged as a single piece from premium 20CrMnTi alloy steel, it undergoes advanced heat treatment with a carburization depth exceeding 1.8 mm, achieving a working surface hardness of HRC60 or higher for exceptional strength and toughness. Its PU, NBR, or HNBR sealing elements deliver outstanding wear resistance, ensuring over 300 hours of effective service and long-term reliable performance in harsh drilling conditions.
