Full Open Valve & Seat for F-1600 Triplex Mud Pump

HNA offers 5different styles of valves & seats to fit your drilling needs, suiting toalmost all popular mud pumps in the world.

The Stem Guided valveand seat and the Wing Guided valve and full open seat offers many advantagesfor today's higher pressures and faster drilling operations.

Stem-guidedvalve &Tri-arm seat features greaterfluid flow than four-arm seats, as well as it features an extra wide metal tometal seal on the valve flange. The serrated upper surface on the valve gives alonger non-breathing seal between valve body and insert while the rigid seatcross-arms give greater strength and positive sealing.
The strong, thick, valve knock off nut holds the insert tightly reducing flexand breathing which lessens the chance of foreign matter getting between valveand insert.

Tri-wingguided valve & Full open seat

Three-wing guidedvalves and full open seats features greater fluid flow than four-wing valves,the unibody forged valve features greater strength than traditional welded-wingvalve. Innovative unibody valve design eliminates snap rings, plates or keepersproviding reduced maintenance by snap-on valve inserts and easy installation.

HNA makes two stylesof Four-wing guided valves and full open seats which feature greater fluid flowthrough the full open seat. The full open seat provides easier valvemaintenance and seat pulling, in valve-over- valve fluid ends.

Innovative unibody Four-wingguided valve designeliminates snap rings, plates or keepers providing reduced maintenance bysnap-on valve inserts and easy installation. This combination will handle lostcirculation material better than most conventional style valves and seats whilethe seating angle greatly improves flow characteristics and the heavy-duty loadbearing capacity greatly improves service life.

The unibodyforged Four-wing guided valve & Full open seat features greaterstrength than traditional welded-wing valve. Innovative unibody valve designeliminates snap rings, plates or keepers providing reduced maintenance bysnap-on valve inserts and easy installation.
