Drillmax® Shear Relief Valves

Drillmax® Shear Relief Valves

Drillmax Shear Relief valves are known for their dependability and effectiveness and are usually installed on the discharge end of the mud pump. When pressure exceeds the preset limit, the pin is sheared allowing the excess pressure to escape and be re-directed, preventing costly repairs. Different pin diameters are used to set the desired shear pressure. Once the problem is corrected, a new pin can be inserted to reactivate the valve.
