Full Open Valve Seat

Best-all full-open valve is the best performing valve available for the tough conditions seen in today's drilling environment. The single-piece, solid-body construction of this valve provides the strength and rigidity needed for high-pressure drilling operations in the 5,000- to 7,500-psi range. Both the valve and the seat are manufactured from heat treated, forged-alloy steel.

The fully open seat design enables removal of suction valve seats without first removing the discharge valve seats for easy access on valve-over-valve-style fluid ends. This process can result in significant time and labor savings when only a suction-valve seat requires replacement.

The full open seat does not have the support webs that are common on other valve styles, and the result is a uniform distribution of pressure across the entire diameter of the fluid-cylinder valve taper, which reduces the chance of seat washout and prolongs the life of the module.

The snap-on, polyurethane insert on the standard valve is field replaceable. For the most demanding high-pressure conditions, a non-replaceable bonded insert upgrade is available that better resists extrusion and minimizes any chance for lost-circulation material or other debris to breach the seal cavity. All standard inserts are available in polyurethane and are good for 180°F drilling temperatures. We also offer a special, high-temperature compound for drilling-mud temperatures to 220°F.

100% interchangeable with Mission, Southwest, Premium and other brands.
