national mud pump valve & valve seats

OEE Offers 5 Different Styles Of Valves & Seats As Per API 7K Standard To Fit Your Drilling Needs, Suiting To Almost All Popular Mud Pumps In The World. Valves & Seats apply in standard environment with the longest service life of more than 600 hours. The rubber of Stem-guided Valve is fixed on valve by Valve Nut. And our Cross-arm Seat is high-hardness, impact-resistant. OEE’s stem-guided Valve & Seat includes: API-4#, 5#, 6#, 7#, 8#, 9#, which are fit for high pressure jetting drilling.The material of cross-arm seat is 20CrMnMo/20CrMnTi forging steel, carburizing and quenching, thickness is 1.5mm-1.8mm,hardness is HRC 58-62, and hardness of the core is HRC27-33 The 55 angle and screw thread of the valve have.

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.

Stem-guided valve &Tri-arm seat

Features: Greater fluid flow than four-arm seats, as well as it features an extra wide metal to metal seal on the valve flange, The serrated upper surface on the valve gives a longer on-breathing seal between valve bodies and insert while the rigid seat cross-arms give greater strength and positive sealing. The strong, thick, valve knock off nut holds the insert tightly reducing flex and breathing which lessens the chance of foreign matter getting between valve and insert

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 styles 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.

Innovative unibody Four-wing guided valve & Full open seat valve design eliminates snap rings, plates or keepers providing reduced maintenance by snap-on valve inserts and easy installation. This combination will handle lost circulation material better than most conventional style valves and seats while the seating angle greatly improves flow characteristics and the heavy-duty load bearing capacity greatly improves service life.

The unibody forged Four-wing guided valve & Full open seat features greater strength than traditional welded-wing valve. Innovative unibody valve design eliminates snap rings, plates or keepers providing reduced maintenance by snap-on valve inserts and easy installation.
