    Description

    The Supreme Valve and Seat is designed to meet all the demanding drilling conditions in use today. The proven design allows its use in pump maximum pressures and strokes; in water, oil or synthetic based muds. The Supreme valve is available with a standard polyurethane insert or a White Lightning insert . Both the standard polyurethane insert and the White Lightning insert are highly resistant to tear, abrasion, extrusion and are compatible with most of the chemistry in the drilling industry today.

    The valve body and seat are precision machined to exacting tolerances from high strength alloy steel and heat treated to provide a very high surface hardness. The valve body is equipped with a removable knock-on nut so that the insert can be changed if pressures are below 2500 psi. National Oilwell Varco does not recommend the changing of their Mission inserts at operating pressures over the 2500 psi threshold since historical data suggests it is not cost effective.

    The design of the Supreme valve and seat offers maximum flow characteristics. The four-web design of the seat offers additional bearing area so the valve weight can be held to a minimum. The steep bevel angle of the seat allows quick flushing of solid matter and additional metal-to-metal strike area plus a generous sealing area.
