A high-pressure float valve for positioning downhole within a well to control fluid flow includes a valve cage having a pair of side seal grooves each for receiving an exterior elastomeric seal therein and a plurality of cutouts provided on the top end of the valve cage. The valve cage can undergo nitride heat treatment and the internal components are made from 1018 hot rolled steel. The dimensions of a Model 5RF plunger-type valve and Model 5RG flapper-type float valve can be modified to meet the high pressure of a 10 ksi rating.

A reciprocating plunger pump fluid end having increased material thicknesses in typical high stress concentration areas includes locating valves in spherically segmented shaped suction and discharge bores adjacent to chamfered transition areas to provide for reduced stress concentrations, resistance to fatigue failure and erosion and ease of access for maintenance. Among other features the housing includes a valve retainer assembly integrally mounted inside the housing which includes a profile to reduce stresses in the bores and facilitate access for replacement of internal components.

A field portable pipe-mounted pipe cutting system with integral controls. The system includes a torch carriage assembly having a torch for cutting a cylindrical pipe. A saddle and cap ring assembly is secured to the pipe. A ring gear engages the saddle and cap ring. At least one drive gear engages the ring gear. A drive gear step motor rotates the drive gear. A motion control module controls movement of the step drive motor. The lead screw assembly moves the torch carriage assembly longitudinally parallel to an axis of the pipe. A lead screw step drive motor drives the lead screw assembly and a motion control module controls movement of the lead screw step drive motor.
