Repair work on wider seats of parallel slide gate valves and wedges as well as check valves and disks.
Portable machines for grinding flanged pipe ends with metallic lenticular gaskets 140° as per BASF- and DIN 2696 standard
High-speed precision grinding machines for the machining of a build-up weld, sealing surfaces, conical surfaces and bores in valves, cylinders, pump housings and flanges
Portable machines for high-speed grinding of hard sealing surfaces (≥ 35HRC) in high-pressure gate valves and wedges and check valves and disks of various design.
Stationary grinding and lapping equipment
Convert drill press or radial arm drill into a precision valve repair center onsite.
Stationary surface lapping machines, particularly suitable for the lapping of valve disks, axial face seals, and wedges.
Stationary ball lapping machine, suitable for finishing the ball and metallic sealing seats of a ball valve so that they fit together perfectly. The machine produces an exact surface shape between the lapped workpieces.
Grinding table for face grinding wedges, valve disks and other machine components
Grinding and lapping machine with eccentricity for the machining of sealing surfaces/nozzles in safety valves.
Stationary grinding and lapping machine for the machining of sealing surfaces in shut-off valves, wedges, safety valves, etc.
Choke and Control Valves:
Right-angle choke valves
Provide flow management for all service types, including severe service such as high erosion, high pressure, and high temperature.
Inline control valves
Process control systems that deal with high temperatures, high pressure differentials, cavitation, and other severe service conditions.
A range of actuators
To deliver accurate and reliable control of choke and control valves along with meeting the specific requirements of project.
Subsea choke valves and actuation
Subsea choke valves and actuation are relied on to lower costs and optimize production for the life of offshore fields around the world.
Specialty trims to meet all application requirements
In addition to the standard 4-port trim of Master Flo choke valves, we offer a number of other styles to meet low-noise, high capacity, high pressure, well cleanup choke, and other requirements.
