PMV Modular Rotary Valve

PMV Modular Rotary Valve

PMV Modular Rotary Valve

A superior, long-lived modular rotary valve for metering and airlock applications handling powders or small granules.  It offers unmatched durability compared to competing solutions and is engineered and built for the most difficult applications in a plant.  

The modular design of the PMV simplifies maintenance and makes rebuilding practical and cost-effective. 

Typical Applications

  • Silo discharge
  • DSI systems
  • Pneumatic conveying systems
  • Ash handling
  • Pulverized coal/pet coke handling
  • Additives and blending
  • Dust collector or process baghouse
  • Cement
  • Lime, trona, gypsum
  • Co-generation / powerhouse
  • Activated carbon
  • Metallurgical coal
  • Calcium carbonate
  • Diatomaceous earth

Key Advantage

  • Dramatically longer life than traditional cast-iron rotary valves.  2-4x the usable life of commodity cast iron rotary valves, depending on application and material.
  • Predictable reliability avoids unscheduled downtime.  Outage-to-outage durability so that maintenance or replacement can be scheduled in a non-emergency manner
  • Compact design is a “universal replacement” for valves from others.   Small footprint minimizes or eliminates retrofitting effort and expense
  • Industry-best rotor-to-barrel clearance to minimize blowby (leakage) in pneumatic conveying applications or under vacuum
  • Modular design makes field repairs a reality. Saving money and reducing the investment in spares
  • Components and designs for applications up to 1200° F
  • Compliant with NFPA 69 and 85 standards

The PMV Does It Better

Handles highly abrasive applications with ease, where commodity valves wear out too quickly; increasing cost of ownership, threatening unplanned downtime, and/or disrupting your process.

Especially suited to pneumatic conveying systems, including DSI systems for pollution control, where conveying rates decline or fluctuate due to excessive or increasing blowby that robs the system of motive air or fluidizes the material above the valve.
