Full Open Valve for Mud Pump

Our full-open valve is the top performing valve available for the extreme conditions seen in today’s drilling environment. The single-piece, solid-body construction of this valve provides the strength and rigidity needed for high-pressure drilling operations in the 5,000- to 7,500-psi range. Both the valve and the seat are manufactured from heat- treated, forged-alloy steel. The fully open seat design enables removal of suction- valve seats without first removing the discharge valve seats for easy access on valve-over-valve-style fluid ends. This process can result in significant time and labor savings when only a suction-valve seat requires replacement. The seat does not have the three or four internal support webs that are common on other valve styles, and the result is a uniform distribution of pressure across the entire diameter of the fluid-cylinder valve taper, which reduces the chance of seat washout and prolongs the life of the module. The slip on or snap-on, urethane insert on the standard valve is field replaceable. For the most demanding high-pressure conditions, a non- replaceable bonded insert upgrade is available that resists extrusion and minimizes any chance for lost-circulation material or other debris to breach the seal cavity. All standard inserts are available in urethane and are good for 170° to180°F drilling temperatures. We have available a special, high-temperature compound for drilling-mud temperatures to 200°F and higher.
