The DrillmaxPro® float valve line includes 5 sizes of Models F, G, and GC, which are rated for a maximum differential pressure of 10,000 PSI. These valves are suitable for sustained temperatures of up to 400°F and H2S sour gas applications.
Float valves for drill pipes can be installed in one or multiple tool joint locations in the drill string, and are designed to prevent the backflow of drilling mud or other media, protecting the drill bit and other tools from damage caused by well cuttings.
Additionally, float valves for drill pipes contribute to safety on the rig by assisting in well pressure control.
Drillmax manufactures a complete line of float valves for drill pipes, also known as “blue valves,” designed for optimal performance and reliability. The blue float valve prevents drilling fluids, cuttings, and metal debris from flowing back up the drill string. When properly installed in the drill string, these blue valves provide enhanced blowout prevention.
Drillmax float valves for drill pipes (DP) are available for standard service, H2S service up to 300°F (HNBR/HSN), and H2S service up to 400°F (Viton).
Drillmax gate valves are designed to meet the rigorous requirements of today’s oilfield applications. The seats are designed for a full, tight seal after each closing cycle. Once closed, the line pressure forces the gate against the downstream port, sealing it against the rubber seat.
Drillmax also manufactures 7500 PSI gate valves modified from a 5000 PSI DM design. Both the 5000 PSI and 7500 PSI gate valves meet and/or exceed the high-pressure demands of deep well drilling.
Drillmax shear relief valves are known for their reliability and efficiency, and are typically installed on the discharge end of the mud pump. When the pressure exceeds the preset limit, the pin shears, allowing the excess pressure to escape and be redirected, preventing costly repairs. Different pin diameters are used to set the desired shear pressure. Once the issue is corrected, a new pin can be inserted to reactivate the valve.
Available in 2-inch and 3-inch connection sizes.
Shear relief valves are available for maximum shear pressures of 1000, 2750, 5000, and 7500 PSI.
They help prevent costly repairs due to overpressure events.
Shear pins are color-coded for easy selection of the correct shear pressure.
