Stem-guided Valves & Three-arm Seats

Stem-guided Valves & Three-arm Seats
Stem-guided valve & Three-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 non-breathing seal
between valve body 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.


Stem-guided Valves & Cross-arm Seats
The Rubber of Stem-guide Valve is fixed on valve by Valve Nut and our Cross-arm Seat is high-hardness, impact-resistant.
KWOM’s Stem-guide Valves & Cross-arm Seats include: API-4#、5#、6#、7#、8#、9#, which are fit for high pressure
jetting drilling.


Three-wing Valves & Full-open Seats
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 reduced maintenance by snap-on valve inserts and easy installation.


Four-Wing Valves & Full Open Seats
KWOM 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.
Innovative unibody 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.
