They feature greater fluid flow through 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 services life.
