MPI (Motion Industries, Inc.) is a large distributor of industrial maintenance, repair, and operations (MRO) supplies, not a manufacturer of valves themselves. They don't produce valves; instead, they distribute a vast array of valves from numerous reputable manufacturers. Therefore, the answer isn't a simple list of "MPI valves," but rather a description of the types of valves available through their extensive network.
To understand what types of valves you can source through MPI, you need to consider the breadth of their product offerings. They cater to various industries, meaning their valve selection is incredibly diverse.
Types of Valves Available Through MPI's Distribution Network
MPI's vast catalog likely includes valves categorized by:
1. Valve Type:
- Ball Valves: Simple on/off control, known for their durability and quick operation. Available in various materials (brass, stainless steel, PVC) and sizes.
- Butterfly Valves: Compact design suitable for large-diameter pipelines, offering good flow control. Often used in throttling applications.
- Gate Valves: Used for fully open or fully closed positions, offering minimal flow restriction when open. Ideal for large-diameter pipelines and infrequent operation.
- Globe Valves: Provide more precise flow control than gate valves, suitable for throttling and on/off applications. Offer good shut-off capabilities.
- Check Valves: Prevent backflow in pipelines, ensuring unidirectional flow. Various types exist, including swing check valves, ball check valves, and lift check valves.
- Control Valves: Used for precise regulation of fluid flow, often incorporating pneumatic or electric actuators. These are critical in process control systems.
- Safety Relief Valves: Designed to protect systems from overpressure by automatically relieving excess pressure. Essential for safety in many industrial settings.
- Diaphragm Valves: Feature a flexible diaphragm separating the fluid from the valve mechanism, suitable for corrosive or viscous fluids.
2. Valve Material:
The material used depends heavily on the application and the fluid being handled. MPI likely stocks valves made from:
- Stainless Steel: Offers corrosion resistance and high strength, ideal for many industrial applications.
- Brass: A cost-effective option for less demanding applications, providing good corrosion resistance in some environments.
- PVC/CPVC: Suitable for chemical handling and corrosive fluids, but with limitations on temperature and pressure.
- Cast Iron: Durable and cost-effective for some applications, but susceptible to corrosion.
- Ductile Iron: A stronger and more corrosion-resistant alternative to cast iron.
3. Valve Actuation:
How the valve is operated also varies widely:
- Manual: Hand-operated valves, suitable for infrequent operation and smaller systems.
- Pneumatic: Operated by compressed air, providing automated control for larger systems.
- Electric: Operated by electric motors, often integrated into control systems for precise and remote operation.
- Hydraulic: Operated by hydraulic pressure, offering high force for large valves or high-pressure applications.
How to Find Specific Valves Through MPI
To find specific valves, you'll need to contact MPI directly or search their online catalog using specific keywords related to the valve type, material, size, and application. Be as specific as possible in your search to narrow down the results.
This comprehensive overview should give you a good understanding of the broad range of valves available through MPI's distribution network. Remember, they are a distributor, not a manufacturer, so their offerings reflect the diversity of the valve industry itself.
