Fluid End Accessories Valves & Seats

Dawopu manufactures a full range of drilling rig mud pump valves and seats for every drilling and well-servicing application as part of our full line of Osprey® mud pump system solutions. All of our valves and seats can be used in water, water base, oil base and synthetic base mud applications. Dawopu offers additional valves and seats not listed below, including drilling valves, frac valves and well service valves. Dawopu’s QC standards for the dimensional and material specs are extremely rigid in comparison to other manufacturers. Contact your Dawopu representative to learn more.

Full Open

The full open style performs well in extreme conditions such as high-solids and high-pressure applications. This valve is based on the roughneck design and is fully interchangeable with other major manufacturers. The improvement to the original design is based on minor dimensional changes on the valve insert groove to accommodate a better fit between the valve and the valve insert.

Full Open High Temp.

The valve insert material is rated for high-temperature applications and should be used at temperatures above 180°F, up to a maximum of 240°F. It distinguishes itself from other manufactured high-temp valves by maintaining critical properties for abrasion resistance and
tear resistance.

Full Open Extra High Temp.

The valve insert material is rated for high-temperature applications and should be used at temperatures above 300°F. It distinguishes itself from other manufactured high-temp valves by maintaining critical properties for abrasion resistance and tear resistance.

4-Web Center Guided

A well-proven design that allows for easy replacement of the valve insert in the field. The valve is designed for use in low-solids applications and pressures up to 6,000 psi. This valve does interchange with other major manufacturers. The 4-web valve and seat are based on an existing design known as the mud king or supreme style valve.

4-Web Center Guided High Temp.

Designed for use in low-solids applications, and pressures up to 6,000 psi. Designed for easy replacement of the valve insert in the field with a split plate/retainer system. This style has over 50 years of proven field service. It does include an option for a rubber insert which allows for high-temperature applications up to 240°F.

Double Angle 3-Web Center Guided

The double-angle o-ring has proven to be the most well-designed valve and seat on the market today. The valve is designed with a tough one-piece body and a “double angle” 55° seal contact surface, which maintains cylinder priming during shutdown. The configuration gives maximum containment of the insert with minimal material. This style performs well in extreme service conditions such as high-pressure and high-solids applications. This design utilizes a snap-on insert.

Replaceable 3-Web Center Guided

This style performs well in lower-pressure applications, up to 5,000 psi. The center-guided design with a single stem at both the bottom and top of the valve allows for an excellent alignment when opening and closing during operation.
