precision machined valve stem company


CNC Valve OEMs

Here at MMS, our specialty is in the manufacturing and rebuilding of control valve components. For the last 40 years we’ve set the industry standard in producing congruent OEM valve trim parts such as plugs, stems, cages, seats, bonnets and guide bushings for virtually every control valve manufacturer in all shapes and sizes. We can reverse-engineer any valve part, new or used, with our hi-tech CMM equipment. MMS stocks a wide range of mill-certified metals and alloys such as multiple varieties of stainless steel, Inconel®, Hastelloy® and tungsten-carbide. Our machine shop capabilities range from state-of-the-art CNC machining to precision grinding to hard surfacing and coatings such as Stellite® overlay, Ion-Nitride, heat-treating and HVOF. MMS can apply hard-surfacing on all critical areas such as seated and wear locations in order to extend the user-life of your valves. This hard surface provides protection against cavitations, flashing / erosion, vibration / noise, turbulence, corrosion and abrasion that can so often occur. MMS also prides itself on providing emergency services and exceptionally fast delivery on all new parts & repairs, especially during forced outages. If you have a valve question or need support, please call one of our sales reps for immediate assistance.

What is CNC Machining?

Computer Numeric Control or CNC machining is a manufacturing process in which computer software is programmed to dictate the movement of factory tools and machinery. Being CNC qualified means the broaching process is completed on CNC lathes and CNC mills instead of transferring parts to a separate key seater or broaching machine or vending your parts out. CNC Machining enables you to make your part completely in one operation and location. This eliminates human error and produces perfectly precise results.
