SELF-CLEANING ROTARY VALVES

PMDS Rotary Valve

#
Documents
REQUIREMENTS
Metering and airlock application for handling very large volumes of limestone and other raw materials. Typically used with a VRM (vertical roller mill).
PRECISION SOLUTIONS
  • Extreme-duty PMCA rotary feeders in sizes from 150 to 1000 TPH.
  • Constructed of Tri-Braze abrasion-resistant steel.
  • Hot-air design for raw material applications.
  • Transitions for slide-out/slide-in replacement of competitive feeders.
KEY DIFFERENTIATORS
  • Two years of operation between rebuilds
  • Reduced false air induction
  • Low or no recurring maintenance

WOOD, ORGANIC AND ALTERNATIVE FUEL FEEDERS

PMV Rotary Valve

#
REQUIREMENTS
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.
PRECISION SOLUTIONS
  • Hardened stainless steel knife slices large pieces.
  • Meters material of all shapes & sizes.
  • Super-tight clearances to avoid false air introduction.
  • Perfect for organic material!
KEY DIFFERENTIATORS
  • Abrasion resistant.
  • Rebuildable.
  • Low or no recurring maintenance.

MINERAL METERING VALVES

PMR Rotary Valve

#
REQUIREMENTS
Functionally, the PMR is both a metering device and an airlock. PMR valves are built for long, continuous operation with provisions for eventual rebuilding.
PRECISION SOLUTIONS
  • Meter abrasive minerals and powdery materials.
  • Built with specialty 500-Brinell abrasion-resistant alloys
  • High-Temp!
  • Save energy!
KEY DIFFERENTIATORS
  • Minimial rotor-to-barrel clearances limits blowby.
  • Optional Tri-Braze barrels can double the cycle between rebuilds.
  • Modular- Wear item replacement.

DUST COLLECTION VALVES

PMSE Side-Entry Rotary Valve

#
REQUIREMENTS
A long-lived offset or side-entry rotary valve designed to minimize shearing and breakage in the handling of delicate, formed, molded, granular, or pelletized materials. Functionally, PMSE valves are both a metering device and an airlock.
PRECISION SOLUTIONS
  • Tight tolerances-Minimizes blowby!
  • Keeps the trapped air from escaping!
  • Precisely meters the material!
  • Easily handle a variety of material types and sizes.
KEY DIFFERENTIATORS
  • Pneumatic line injectors.
  • Extremely durable. Built with 500 Brinell wear parts.
  • Rebuildable! No throw away components here!

FLY & BOTTOM ASH FEEDERS

PMRD Rotary Feeders

#
REQUIREMENTS
A durable high-capacity rotary feeder for handling dry powders, granular materials, small rocks, or other abrasive materials with relatively uniform material size and low moisture content. Offers an attractive capacity-for-cost ratio compared to tight-tolerance rotary valves. Functionally, both a metering device and an airlock.
PRECISION SOLUTIONS
  • Combined durability & functionality.
  • A metering device AND airlock.
  • Able to easily process massive amounts of fly and bottom ash.
  • Maximum throughput.
KEY DIFFERENTIATORS
  • Rounded rotor pockets
  • Ion-nitride treated to provide exceptional durability and abrasion-resistance.
  • Low or no recurring maintenance
