Best-all four-web, center-guided valve has been one of the most popular valve styles in the oil field. It is the preloaded polyurethane insert secured with a threaded retainer plate with knock-off lugs for easy disassembly. This design enables drillers to change valve inserts quickly and minimizes downtime. The valve is best suited for low- to medium-pressure drilling operations because of the two-piece assembly of the valve body.
The center-guided design enables the valve flange to be supported under pressure loads by the top of the center-support webs in addition to the seating taper on the inside of the valve seat. This allows for a large bearing area for the valve that minimizes stress and promotes a long service life.
Our standard valve is offered with polyurethane inserts rated for 170° to 180°F (77° to 82°C) drilling-mud temperatures. We also offer a special high-temperature urethane compound as an option for high-temperature drilling conditions to 220°F (104°C) and higher.
100% interchangeable with Mission, Southwest, Bake SPD and other brands.
