Precision Well Control kelly, safety, top drive and internal blowout preventer valves are the preferred solution for drilling and workover companies to control flow in wellbore tubulars.
The patented EZ-FLOW CARTRIDGE takes the quality of our standard service valves to a new level. This valve’s unique floating ball and spring-loaded seat design forces pressure and flow through the seat, not around its exterior. This eliminates unreliable single direction seat seals, erosion and fouling/binding frequently seen in competitive designs. The floating vented ball and double floating seats guarantee differential pressure by acting only across the downstream side of the ball & seat to minimize the load, prevent distortion of the ball and protect seat support arms. Combining these features with a proprietary stem bearing reduces the torque required to operate the valve by 50% compared to other designs.
