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, en]suring over 300 hours of effective service and long-term reliable performance in harsh drilling conditions.

Features:

1) Material of body and seat: 20CrMnTi/20CrMoCi
2) Valve insert material: NBR, CPU, TPU
3) Structure: full open style, three web style, four web style
4) Depth of Carburized Layer: 1.80~2.22mm
5) Hardness: HRC60-65
6) Temperature tolerance property: -60ºC~100ºC
7) high strength, high toughness, high precision sizes.

Classification
