Features, Advantages and Benefits
The threaded retainer plate with knock-off lugs enables fast insert change-out.
The large bearing area on the valve promotes a long service life.
Various insert materials are available to meet standard and high-temperature drilling conditions.
Carbon-steel valve springs are standard, with a long-life, stainless-steel upgrade available.
The key feature of the four-web, center-guided valve 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 200°F (93°C) and higher.
