PMV Modular Rotary Valve

Experience what a revolution in design can do for your operation.  The modular design of our rotary valve makes service and repair a snap.  The materials and workmanship provide the tight tolerance and long-lasting durability that you need from a metering or airlock device.

PMR Rotary Feeder

PMR Rotary Feeder

The PMR rotary feeder combines a stationary tool-steel knife and a rotor with helical vanes to provide a shearing action for cutting off oversized materials in a feedstock, minimizing jamming or interruption of the feed. Functionally, the PMR is both a metering device and an airlock. PMR feeders are built for long, continuous operation with provisions for eventual rebuilding.

PMDS Self-Cleaning Rotary Valve

A Self-Cleaning Rotary Valve? Absolutely!
Material build-up in the pockets of rotary valve can be a real problem. Throughput can be reduced or become inconsistent. You’ve got to stop production and clean it out. The Precision PMDS Self-Cleaning rotary valve is a reliable, trouble-free solution to this problem.

PMRD Rotary Valve

PMRD Rotary Feeder

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.

PMCA Rotary Feeders

Feeding raw materials and clinker in a cement manufacturing plant is a demanding job.  Huge volumes of abrasive materials and 24/7 operation for months at a time add up to a real challenge for rotary feeders.  Precision’s PMCA family of feeders were specifically designed for these tough conditions.

Fuel Handling Screw Conveyors

Fuel bin and transport screws for moving mixed, wood-based fuels from storage to the boiler or kiln. Designed for holding up to abrasive, poor-quality fuels, Precision’s fuel handling screws are built for extreme-duty and to run from outage-to-outage with no downtime.

Ash Handling Screw Conveyors

screw conveyor ash handling multiple

Extreme-duty, abrasion-resistant screw conveyors for moving fly ash and bottom ash away from boilers. Fly ash at 250° F and bottom ash at 600-700° F require materials and designs that tolerate continuous exposure to elevated temperatures.

PMSE Side Entry Valve

PMSE side-entry rotary valve

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.

PMX Rotary Valve

PMX Rotary Valve

A high-capacity rotary feeder for introducing cement raw materials, principally quarried limestone, into a vertical roller mill (VRM) or another type of raw mill. U

Micro-Valve

The Precision Micro-Valve’s innovative design was developed to handle small to medium applications. It is ideal for metering a precise amount of an additive to an in-process application.

PMA Rubber-Tipped Airlock

PMA Rubber-Tipped Airlock 01

Precision PMA rubber-tipped airlocks are a heavy-duty, fully fabricated airlock intended for use with mild to moderately abrasive materials where a tight airlock seal is required. 

Let our applications specialists help you with your extreme-duty bulk material handling needs.
