Four-wing valves&full open seats :
DL offers two types of four-wing guided valves and full open seats features greater fluid flow through the fuu-open seat.The full open seat provides easier valve maintainance and seat pulling,in valve-over-valve fluid ends. Innovative unibody valve design eliminates snap rings,plates or keepers providing reduced maintainance by snap-on inserts and easy installation.This combination will handle lost circulation material better than most conventional style valves&seats while the seating angle greatly improves flow characteristica and the heavyduty load bearing capacity greatly improves service life.
