   OEE offers 4 different styles of valves & seats to fit your drilling needs, suiting to almost all popular mud pumps in the world. The Stem Guided valve and seat and the Wing Guided valve and full open seat offer many advantages for today's higher pressures and faster drilling operations. Three-wing guided valve & Full open seat Three-wing guided valves and full open seats features greater fluid flow than four-wing valves, the unibody forged valve features greater strength than traditional welded-wing valve. Innovative unibody valve design eliminates snap rings, plates or keepers providing. Four-wing guided valve & Full open seat OEE offers two style of Four-wing guided valves and full open seats which feature greater fluid flow through the full open seat. The full open seat provides easier valve maintenance and seat pulling, in valve-over- valve fluid ends.

The chrome-plated liners have hardening characteristics of 58 to 62 Rockwell C hardness. Material is 45# forged steel, tensile strength is larger than 450MPA, elongation is larger than 17%, hardness is HRC180-200. The bore is plated by chrome, thickness is 0.15-0.18mm, hardness is HRC 58-60.4)Hardened liners: Hardened liners offer economy in a liner that is made for normal to mildly corrosive mud conditions. These liners are hardened and heat treated under strict quality control to a minimum of 60 RC hardness and a depth of 125 inches. Each liner is honed to a mirror-like finish for smooth and even wear during the life of the liner and is machined to close tolerances to assure easy installation and long life.

To get better fiber texture, we use electric stove for second forging, or deoxidation treatment. It is forged from three directions and the forging ratio is not less than 4.0:1.0. It can not have crack, impurity, looseness, overburns, etc. And weld is not allowed. It should be confirming to the stipulation of JB/TQ252-81, and should be checked by gradeⅢ After quenching the rough module will be rough processed, then the hull hardness is HB285-330.
